Pyrometers
The measurement and control of temperature in Industrial processes are important from the point of energy management, productivity and product quality. Many temperatures measuring tasks can be attempted with contact-type sensors like Thermocouples and Resistance Temperature Detectors. However, if the measurement needs a fast response, no adverse effects on temperatures and materials, measurement of moving objects, objects which are difficult to access, electricity conducting objects, Small objects or aggressive materials like corrosive and molten metals Infrared non-contact Pyrometer is the right solution.

Infrared Non-contact pyrometers measure object surface temperature without physical contact. However, how is it possible to measure temperatures without physical contact? Every object whose temperature is above absolute zero (-273.15 °C) emits radiation. This emission is heat radiation and is dependent upon temperature. Infrared radiation transports energy. This radiated energy is used to help determine the temperature of a body being measured. Pyrometry, being part of a highly specialised field of measuring techniques, has developed a certain mysterious aura about it. In fact, Tempsens pyrometers are easy to operate in industrial applications so long as the basic principles are known and observed.
Due to its accuracy, speed, economy and specific advantages, pyrometry is well accepted in Industrial and R&D applications.

FAQ
Frequently Asked Questions
Find answers to frequently asked questions related to Pyrometers.
A Pyrometer is a non-contacting device that intercepts and measures thermal radiations, without making any contact with the radiating body and the process is known as Pyrometry. This device is useful for determining the temperature of an object’s surface.
Pyrometer strictly works on the principle of black body radiation. Here emissivity of the target plays an important role, as it governs how bright the target appears to the pyrometer. Due to its high accuracy, speed, economy and specific advantages, it is widely being used as a standard procedure in many industrial applications.
Working:
- An optical system gathers the visible and infrared energy from an object and focuses it to the detector.
- The detector receives the photon energy from the optical system and converts it to an electric signal to drive a temperature display or control unit.
- Temperature Range:
Basic requirement to choose a pyrometer is to know the temperature range of the application. - Spectral range:
The material of the measured object demands the correct selection of spectral range of pyrometer. - Field of View (D: S ratio):
The larger the measuring distance/spot size (D:S) ratio, the higher the optical resolution. The spot size has to be as big as the measured object to achieve a correct temperature measurement. - Sighting:
For easy focusing of pyrometers to measure object, different sighting system are available i.e. aiming and View finder. - Records of the data:
Data logging and companion software for data storage, retrieval and analysis. - Calibration of Pyrometer:
A Pyrometer should be calibrated at desired temperature ranges.
- Ability to monitor temperature in situations where the object is inaccessible or moving.
- Where the object may be contaminated or damaged by a contact sensor.
- Where contact is not possible due to extremely high temperatures, or where the object is electrically active.
- An Infrared Thermometer can be mounted remotely from the hot target, enabling it to operate for long periods with minimal maintenance.
- Lightweight, User Friendly and Compact.
- Very fast response time in tune of msec.
Pyrometers have wide range of diverse applications in various industries:
- Glass Industries
- Steel Industry
- Cement Industries
- Power Industries
- Non-Ferrous Industries
