Tempsens laboratory and industrial ovens operate at ambient temperature conditions and up to an overheating model 500°C for specific applications.

Industrial furnaces are primarily engineered to perform heat treatment, materials processing and quality control testing.

Industrial heating furnace systems provide temperature capabilities in the range of 500°C to 3000°C depending on the specific high temperature furnace application requirements.

Power usage ranges considerably depending on industrial furnace size, temperature requirements, and insulation performance, usually between 10kW and 500kW for most common industrial heating applications.

With the exception of the benchtop Deben Fugaku, most Tempsens furnaces provide gas purging with inert gases such as argon, nitrogen, and hydrogen for specific processing needs.

Basic safety features include over-temperature protection, door interlocks, emergency shutdowns, and exhaust systems for hazardous vapor management.

Tempsens laboratory furnaces have capabilities from 500 degrees Celsius to 3000 degrees Celsius, whereas most standard models will operate between 500 degrees Celsius to 1800 degrees Celsius based on application requirements.

calibrate sensors

, and inspect door seals. These simple steps ensure top performance and extend furnace life.

Typical applications for laboratories in the UAE are for materials testing, ceramic processing, pharmaceutical analysis, semiconductor manufacturing, heat treatment or analysis in various sectors of research and industry.

Consideration on maximum temperature for your furnace, sample size, atmosphere (if any) control, heating rate, uniformity specifications, and safety certification related to your application.

General comfort heating is between 20-24°C (68-75°F). Tempsens systems offer exact temperature control with a tolerance of ±0.5°C.

The main types of heating systems include underfloor radiant heating, cable systems, mats, and snow melting applications especially suited to specific environments.

The most comfortable heating system depends on the use and applications of the user depending on what they require. Every product has its own speciality.

Our furnace heaters cover all temperature ranges from ambient to 1600°C. Standard heaters are rated to 1100°C. Silicon carbide and molybdenum disilicide elements are used for the most demanding high temperature applications of up to 1600°C.

Your selection is dictated by operating temperature, atmospheric conditions, power requirements and furnace geometry. Tempsens' technical team can fully consult with you to recommend the best thermal furnace solution based on your industrial requirements for the Gulf.

Regular visual inspection of heating elements and electrical connections are important. The maintenance schedule is specific to the electric furnace heater type, and Gulf operating conditions, and is supported by Tempsens' maintenance manuals.

Industrial electric heaters utilize electrical power for heat generation, providing accurate control, reduced maintenance, and zero emissions. Gas heaters involve combustion and are commonly appropriate for larger-scale or open spaces but need ventilation and increased safety measures.

Industrial heating elements are used to heat liquids, gases, solids, or surfaces in a variety of industries, including oil and gas, chemical, pharmaceutical, power, and food processing. Applications include tank heating, pipeline tracking, furnace operations, and drying systems

Yes, Tempsens can develop unique industrial heating elements to fulfill special process needs, temperature ranges, mounting requirements, and environmental exposures — with the highest performance and safety.

Choose according to process temperature, medium (liquid/gas), environment (hazardous/safe), kind of heater (immersion, duct, circulation), wattage, and material compatibility. Taking professional help from industrial heaters manufacturers such as Tempsens assures the perfect fit.

Heat flux is also called thermal flux, heat flow density, or the rate of heat transfer per unit area, within thermal engineering use.

Heat flux measurement is fundamental to process optimization, safety monitoring, energy efficiency assessment, and thermal system design for both industrial and research applications across the Gulf region.

Cooling options: Water cooling is recommended for measurements above 5 W/cm² lasting more than 5 minutes, or when sensor body temperature may exceed 200°C.

To measure heat flux, a custom sensor is placed onto the surface to measure differences in temperature and calculate output following this formula: Heat Flux (W/cm²) = Sensor Output (mV) X Sensitivity Factor (W/cm²/mV).

Our sensors provide ±3% to ±5% accuracy depending on the model, with repeatability of 2%.

All sensors provide 10mV linear output at full scale range with infinite resolution, requiring no external power supply.

Standard sensors measure total heat flux (radiation + convection). Radiometer versions with windows measure radiation only.

It depends on usage conditions. We recommend annual calibration for critical applications or after exposure to extreme conditions.

All sensors include manufacturer calibration certificates. ISO standard calibrations are available upon request.

Silicone oils or alcohols based on the temperature range — we include recommendations and compatible fluids with each unit. 

RTDs, and thermocouples can be calibrated in the liquid bath temperature calibrator.

Tempsens provides benchtop and portable liquid bath calibrator models with applications in the field and lab.

Constant agitation, profound immersion, and thermal equilibrium guarantee consistent and stable temperature areas for accurate calibration.

Tempsens optical fiber temperature sensor technology is based on the detection of change in the properties of light, these include fluorescent decay time or the shift in wavelengths due to temperature changes. Optical signals are converted to accurate temperature measurements.

Testing optical sensor systems includes calibrating the fiber optic temperature sensors against references, checking signal integrity on the optical sensor, and conducting environmental validation to ensure operational temperatures are measured effectively amidst any electromagnetic interference.

• Black body calibration is the comparison of the device to NIST traceable references using accurate temperature sensors and following established metrology practices.

• Detection of black body radiation uses calibrated infrared sensors, thermal imagers, or pyrometers that measure the fundamental electromagnetic spectrum of the heat coming from the heated cavity.

• A black body is used to measure and calibrate non-contact temperature devices, including pyrometers, thermal imagers, and IR thermometers by providing a uniform radiation source.

Thermowells protect the sensor from process conditions, allow for hot replacement, lower maintenance costs, and reduce uncertainty in measurement while maintaining the integrity of system pressure.

Selecting the right

The basic parts of a thermowell are: stem body, tip shape, process connection (threaded, welded, or flanged), and protective tube which holds the temperature sensor in place.

Installing a thermowell includes finding the appropriate types of thermowell based on your process conditions, the appropriate insertion length, or depth before performing the work to ensure the process connection is secure, and then inserting the thermowell sensor assembly.

Thermowell frequency is defined as the wake frequency calculations completed in the design in order to limit the possibility of failure due to vibration to assure the long-term operational safety of the design and goal of product compliance.

• Metallic tubes are fabricated or machined from SS, Inconel, or Monel and offer strong protection in high-velocity or high-pressure fluid systems.

• Threaded, flanged, socket weld, and Van Stone are popular, with varying advantages in installation, maintenance, and strength.

• Fabricated thermowells consist of several pieces that are welded together, ideal for low to moderate process conditions, and provide economical protection.

• Barstock thermowells are machine-turned from solid metal bars, offering exceptional mechanical strength and toughness for high-stress applications.

• Van Stone thermowells are made from a single bar with a slip-on flange, with a leak-free seal without having to weld the flange.

• Typical tip profiles are straight, tapered, stepped, and helical—each one suited to optimize response time, strength, and flow resistance.

• Thermowells are composed of a stem (shank), tip (sensing end), and process connection. They’re built to house sensors while withstanding process conditions.

• Shank construction is the shape of the stem (straight, stepped, or tapered), which influences strength and response time of the sensor.

• Types of Flange are raised face (RF), flat face (FF), and ring-type joint (RTJ), depending on pressure rating and sealing surface.

• Welding types are full penetration welds, fillet welds, and socket welds, each of which is qualified for strength and leak-tight performance.

• WPS specifies the way welding is done; PQR checks it through testing. Both ensure welds are safe and of quality.

• Special coatings such as PTFE, ceramic, or carbide resist corrosion, scaling, and abrasion in tough environments.

• Normal tests involve hydrostatic pressure tests, dye penetrant examination, radiography, material testing, and dimensional inspection.

• This checks chemical composition and mechanical properties to guarantee ASTM or ASME conformity.

• It verifies all important dimensions such as insertion length, bore, and flange alignment according to drawing specifications.

• This test places high fluid pressure on the thermowell to verify its seal and structural strength.

• DPI is a non-destructive inspection that identifies surface cracks or welding flaws by using a fluorescent or visible dye.

• Radiographic examination employs X-rays or gamma radiation to identify internal flaws or discontinuities in welds and wall thickness.

• Frequency limits, as specified by ASME PTC 19.3 TW-2010, forestall resonance and vibration-induced failure due to flow-induced turbulence.
  

• Stress on the thermowell is minimized at low velocity, enabling longer insert lengths or weaker profiles.
  

• Select the thermowell material according to the temperature range and the environment (corrosive, oxidizing etc.) in which it is to be used.
  • These wells can be made from different materials like SS304, SS316, HRS446, Inconel, Monel, Ceramic, etc.
• According to the construction of Thermowell (Steeped Shank, Straight Shank, Tapered Shank)
  • Steeped Shank- Provide faster response time and lower drag force.
  • Straight Shank- Extremely strong, but response time is slower and drag force on the fluid flow is high.
  • Tapered Shank- Provide good response time and strength.
• Thermowell Insertion Length
  • For best temperature measurement accuracy, the “U” dimension should be long enough to permit the entire temperature-sensitive part of the measuring instrument to project into the medium being measured.
    Liquid temperature measurement: One inch or greater.
    Gas temperature measurement:- three inches or greater.
• Resistance to vibration.
  • Fluid flowing past the well forms a turbulent wake (the Von Karman Trail), which has a definite frequency based on the diameter of the well and the velocity of the fluid.
  • The thermowell must have sufficient stiffness so that the wake frequency will never equal the natural frequency of the thermowell itself. If the natural frequency of the well were to coincide with the wake frequency, the well would vibrate to destruction and break off.
• To avoid the Thermowell failures caused by excessive pressure, drag forces, high temperature, corrosion, vibrations, it is recommended to run thermowell calculations based on your applications:
  • Maximum or operating temperature
  • Maximum or operating pressure
  • Fluid(gas or liquid) velocity
  • Fluid Density.

• Accessories comprise compression fittings, bushings, thermocouple connectors, gaskets, and support collars for installation and sealing.

LV (Low Voltage) cables operate at voltages of 1.1kV and below, and are generally used to wire buildings and supply electricity. MV (Medium Voltage) cables operate at voltages between 1kV and 35kV, and are typically used in distribution systems of electric utilities. HV (High Voltage) cables operate at voltages greater than 35kV, and are used for the transmission of electricity over long distances; they require specific insulation and design for improved performance under varying degrees of electrical stress.

A low-voltage power cable is composed of copper or tin plated copper (from 0.50 mm² to 300 mm²) as electrolytic grade conductors, core insulation made from either PVC, XLPE, or LSZH materials, a screen of either aluminium foil or mesh braid coverings used on the shielded variants, both the inner & outer sheaths protect the core from environmental damage; also available G.I. armour (metal-woven covering) for additional mechanical and impact resistance for difficult installations.

The various types that Tempsens uses include PVC (Polyvinyl Chloride) for standard installations, XLPE (Cross-Linked Polyethylene) to withstand higher heat exposure (up to 90°C), HR PVC (Heat Resistant PVC), LSZH (Low Smoke and Zero Halogen) polymers for fire safety, FR PVC and FRLS PVC, which are flame retardant, along with PE (Polyethylene) or XLPO are used for some extreme applications that comply with IS & IEC Standards.

When High Temperature Cables are used in the UAE they usually operate in an ambient temperature range of -40C to +90C but the conductor operating temperature can be as high as 1200C. Because of this very high operating temperature they will be used in not only very high ambient temperatures but also the extreme temperatures that are associated with the industrial processing of products from desert sand.

PTFE, FEP, silicone, and fiberglass-insulated cables are the best options for high-temperature applications in refineries, petrochemical plants, and floating facilities by using oil, chemicals, and flame-resistant materials for high-temperature applications above 260° Celsius.

The conductor materials for high temperature cables are selected from among annealed bare copper, tinned copper, silver plated copper, nickel plated copper, pure nickel, and NPC 27% alloy based on the temperature and performance of the application.

Operating temperature, voltage grade, conductor size, environmental factors, chemical exposure, degree of flexibility required and relevant standards must all be taken into consideration when selecting a high temperature cable. Refer to the manufacturer’s specifications for assistance in making the best selection.

Heat resistant cables should be chosen based on maximum operating temperature, voltage requirement, conductor size based on current load and environmental exposure (chemicals).

A heat-resistant cable can endure continuous high-temperature service (between 200°C - 800°C) whereas Fire Resistant Cables keep circuit integrity during a fire at "normal" temperatures.

Tempsens cables are designed for continuous use and have a service life of more than 20+ years when installed correctly and within the rated parameters provided by IS 8130.

There are several types of insulation used, and each type will determine how flexible (or stiff) the cable is. For example, Silicone and FEP insulations are very flexible, whereas fiberglass and ceramic fiber insulation provide average flexibility based on the application's needs.

Fire-retardant cables resist initial ignition and slow the spread of flames. Fire-resistant cables are designed to stay functional for limited time periods during a fire event. Fire survival cables are designed to ensure full circuit integrity at temperatures exceeding 750°C for 30-180 minutes, thereby keeping essential emergency safety systems operational throughout and subsequent to varying emergency fire events.

Installation must account for minimum bending radius (6-8 times cable diameter), use of fire resistant/cable retention fixings, adequate segregation away from other cables, fire rated terminations with cable duration rating, and qualified installation per BS 7671 regulation in order not to compromise fire survival integrity.

MI cable is a sheathed Thermocouple Cable, having an outer sheath of metal with Two to Eight Cores where positive and negative thermo elements run around Circular Pattern, embedded in MgO. Mineral Insulated Cables are suitable to high Mechanical, Chemical, and Electrical stability. Due to good Flexibility, Excellent mechanical strength, and pressure resistance, mineral insulated Thermocouples/RTD’s can be installed in complex installations.

Construction:

• One or more wire like conductors (cores) are embedded in a high insulation quality MgO(Magnesium Oxide) and pressed into a metal tube (sheath) made of oxidation and corrosion resistant material. The entire combination is then processed using suitable forming steps to obtain the final dimensions.

Compensating cable is made of alloys which are different from those of thermocouples but have the same output over a limited temperature range. Compensating cable is a connector between thermocouple and measuring instruments, these cables are less precise, but cheaper. They harness quite different relatively low cost alloy conductor materials, whose net thermocouple in question. The combination develops similar output as those of the thermocouple, but the operating temperature range has to be restricted to keep miss-match error acceptably small.

MI Cables cover up the wide area of applications. Important are listed below:

• In Chemical, Petrochemical and fertilizer industries, and as equipment in dairy, food processing, pharmaceutical industries, in hospitals, households as kitchenware, cryogenic vessels and as heat exchanger in air conditioning refrigeration, for machinery in paper, pulp and textile beverage sector.
• Architectural trims, Marine exteriors, chemical processing equipment, food processing equipment, petroleum refining equipment, photographic equipment.
• Nuclear power and reactor construction, chemical apparatus engineering, annealing furnaces, heat exchangers, crude oil industry, grease and soap industry, aircraft exhaust stacks and manifolds, pressure vessels, large mufflers for diesel engines, carburetors, expansion bellows, stack liners, fire walls etc.
• Power technology, recuperates, heat treatment kilns, vortex firing installations, waste incinerators, furnace construction, boilers and blast furnaces, PWR, Space Travel.

Extension cable uses wire of nominally the same conductor as the thermocouple itself, which thus inherently possess similar thermo power characteristics, and with no connection problems. Miss-match error arising from high connecting box temperature is likely to be relatively small. These cable are less costly then thermocouple wire, although not cheap, and are usually produced in a convenient form for carrying over long distance typically as flexible wiring or multi-core cables.They are recommended for best accuracy.

Pyrometers, also known as radiation thermometers, infrared thermometers, or non-contact thermometers, are instruments designed to measure temperature by detecting thermal radiation emitted from an object, without requiring physical contact.

A pyrometer measures infrared (IR) radiation that is emitted from the object being measured without contact, while a contact thermometer measures temperature by making contact with the object being measured.

The spectral range of an infrared thermometer defines the range of wavelengths to which the instrument is sensitive.

Nipples are made up with a flange from the same family on each end of a tube section. (Fittings that are manufactured with different flange families on each end are called hybrid adapters.) Straight nipples are manufactured with the same size flange on each end of straight section of tubing. Reducer nipples have different size flanges (from the same family) on each end.

The three piece unions have to be used in hazardous areas, for the junction between conduits pipes and boxes or various appliances. The unions are made up of three independent pieces that can be screwed up by rotating the same pieces among them.

Following are the two types of termination style:

• Metallic Plugs and Socket Connections
• Standard & Miniature Thermocouple Connectors

The link between the thermoelectric wires of the thermocouple and those of the extension cable is made by means of non – compensated male and female connectors. The metallic body and casing of these connectors ensure the screening continuity as well as good temperature.

Standard & Miniature connectors are ideal for connecting thermocouple sensors and extension or compensating cable to each other. The pins are polarized to avoid an incorrect connection and the connector body is additionally marked for polarity. These connectors have color coding according to special standard like: ANSI, IEC etc.

Platinum has a near linear and extremely stable resistance-temperature relationship and has low drift over time. Pt100 elements have a consistent accuracy, good repeatability and very good material stability over a wide range of temperatures (-200 °C to 850 °C), which makes them the international standard for reasonable accuracy for industrial temperature measurement.Tempsens Pt100 RTDs are specifically calibrated to perform reliably in the challenging conditions found throughout UAE and Gulf industrial environments.

The selection depends on system design:

• Pt100 is preferred for high-accuracy industrial systems using 3-wire or 4-wire configurations, where cable resistance can be compensated.
• Pt1000 is advantageous in 2-wire circuits, long cable runs, and battery-powered or low-power installations because the higher base resistance reduces the influence of lead resistance and lowers self-heating effects.

Both are accurate; the choice is driven by wiring configuration, allowable uncertainty, and installation constraints. A certified Tempsens professional can assist you in finding the best temperature measuring device or technique for your business’s unique needs through their local application engineering expertise located in the UAE and Gulf Regions.

Resistance temperature detectors determine temperature by taking the change in electrical resistance of platinum elements and correlating that change with temperature change. RTDs are used mainly in industrial processes where accuracy and stability are important which include power plants, chemical processing, pharmaceuticals, and oil refining where precise control of temperature is vital in order to maintain a safe and efficient process.

RTD resistance changes in a predictable manner with temperature according to the equation α = (R100 - R0)/(R0 x ΔT) where the linear resistance-temperature coefficient of platinum remains largely unaffected across a broad range of temperature; and since a resistance temperature element (RTD) detects the change in resistance electronically, the change in resistance is converted three ways into temperature with high accuracy and repeatability.

The calculation of RTD temperature requires the use of the Callendar-Van Dusen equation for platinum (PT) resistance temperature sensors for all temperatures less than 0°C is R(T) = R0[ 1 + AT + BT² + CT³(T-100)]. For temperatures in the 0°C to 850°C range the relationship is R(T) = R0 (1 + AT + BT²). The definitions in the equations include R0 as the resistance at 0°C (for example Pt100 is equal to 100Ω at 0°C), A, B, C are coefficients standardized so that performance of the resistance temperature sensor is met within each application.

The RTD sensor’s operating principle relies on the fact that resistance varies with temperature in a known manner, providing accurate and stable temperature readings.

Think about parameters such as temperature range, precision, environment (vibration, chemicals), response time, and installation type. Select materials and construction based on these.

RTDs are applied to steel, pharmaceuticals, food processing, petro, HVAC, aerospace, power plants, and industrial automation for accurate temperature measurement and control.

The Callendar-Van Dusen equation is used to define RTD resistance:
R(t) = R₀(1 + At + Bt² + C(t – 100)t³), where A, B, C are constants.

Common materials are platinum (most precise), copper, nickel, and nickel-iron alloys—selected on the basis of stability, linearity, and corrosion resistance.

Platinum is highly stable and has a large range; copper is economical but low-resistance; nickel is highly sensitive but non-linear.

Platinum RTDs generally function within the range of –200°C to +850°C, whereas copper and nickel versions possess lower temperature thresholds determined by their design and materials.

IEC 751 specifies tolerances for RTD:
Class A = ±(0.15 + 0.002×t)°C;
Class B = ±(0.3 + 0.005×t)°C;
There are other classes such as 1/3, 1/5 DIN which are for greater precision.

They are high-purity platinum RTDs in accordance with ITS-90 standards and used in metrology laboratories for precise and repeatable measurements.

RTDs are made up of a sensing element (wire or film), insulators, leads, and a protective cover. They can be constructed as thin-film, coil-wound, or mineral insulated.

This form employs platinum wire wound into a helix and placed inside a ceramic tube for support, suitable for precise lab and industrial use.

Platinum wire is wound over a mandrel and glass- or ceramic-covered here, providing improved vibration resistance and moderate accuracy.

RTDs operate on 2, 3, or 4-wire configurations. Additional wires ensure the elimination of lead resistance and ensure greater accuracy in measurements.

Simple configuration in which a single lead is connected to both ends of the element. It’s easy but has the effect of lead resistance being measured, which decreases the accuracy.

It’s the most popular industrial setup; it takes care of lead wire resistance if all leads have the same resistance.

Utilized in applications requiring precision, it totally removes lead resistance effects by sensing voltage along a known current path.

RTD wiring generally adheres to color codes: two red and one white for 3-wire; two red and two white for 4-wire configurations.

These RTDs are housed in compacted MgO within a metal sheath, thereby being vibration-resistant and flexible, and suited for harsh environment use.

Typical errors are lead wire resistance, insulation breakdown, self-heating, mechanical stress, and long-term calibration drift.

Conformity guarantees standardized performance from sensors; increased conformity indicates greater interchangeability without recalibration.

Sensitivity is a measure of how much the resistance varies per degree; greater sensitivity enhances measurement resolution and signal intensity.

High insulation resistance avoids shunting errors and insures the RTD’s readings are correct and not affected by leakage currents.

Current measurement induces minor self-heating. If not relieved, it causes errors. Reduced current or improved heat removal lessens the effect.

It establishes the speed with which the RTD responds to changes in temperature. Reduced time constants allow faster response in dynamic applications.

Repeatability guarantees that the RTD delivers the same output for a given set of circumstances, essential for process control and data logging to be reliable and consistent.

Long-term resistance to drift is represented by stability. Platinum RTDs exhibit excellent stability, particularly in harsh industrial environments.

Suitable packaging facilitates heat transfer, guards the element, and maintains precision and quick response in the desired environment.

These are robust RTD assemblies contained in protective sheaths and used for direct immersion or industrial installations within a thermowell.

Probe assemblies consist of the RTD sensor, sheath, lead wires, and mounting hardware to meet process connection specifications.

Flexible RTDs are thin, flexible sensors applied in curved or irregular surfaces, offering quick response and high accuracy in confined areas.

These RTDs are engineered for custom applications like surface mounts, embedded sensors, or flexible strip form in OEM equipment.

RTDs are employed in environments such as process industries, laboratories, pharmaceuticals, aerospace, energy, and HVAC, where accurate and consistent temperature regulation is necessary.

They offer excellent accuracy, enduring stability, wide temperature range, high repeatability, making them ideal for precise temperature control applications.

RTDs are pricier than thermocouples, respond more slowly, and are less applicable at extremely high temperatures (beyond 850°C).

Base metal thermocouples are extremely popular in steel mills, cement kilns, chemical reactors, refineries, boilers, industrial furnaces and general process heating systems for their mission-critical temperature sensing, control and monitoring functionality.

Yes, thermocouples are regarded as heat sensors in UAE and Gulf industries, especially HVAC, oil and gas applications, as they are reliable and durable products.

Most of the Gulf countries technicians test thermocouples by connecting the two thermocouple wires to a multimeter which measures voltage output from the thermocouple. If you obtain a reliable reading in millivolts, it tells you that the thermocouple is operationally valid in that extreme temperature range relative to your application, and safety for your equipment.

type based on temperature range, environment (oxidizing, reducing), sensor shape, and process compatibility.

Thermocouples offer faster response and wider ranges; RTDs are more stable over time. Thermistors are limited to low temps and require complex electronics.

• Hot junctions in thermocouples are formed using TIG or laser welding to ensure conductivity and stability.

Tempsens thermocouples follow IEC 60584, ASTM E230, and ANSI MC96.1 for EMF output and material consistency.

• Thermocouples (R, S, B) are made with platinum-rhodium for high-temperature measurements where a temperature of more than 1200° is required and up to 1750°C.

• Refractory Metal Thermocouples are manufactured from exotic metals like Tungsten and Rhenium. These metals are expensive, difficult to manufacture, and brittle. These are utilized in high-temperature environments and under reducing or vacuum atmospheres, functioning at temperatures up to 2300°C.
