Pressure and temperature gauges represent some of the most elementary parameters governing oil and gas operations they affect well performance, equipment function, fluid characteristics, separation performance, and overall plant reliability. Accurate measurements of these parameters are crucial throughout upstream production, midstream transport, and downstream processing. Tempsens designs and manufactures pressure gauges and temperature gauges for the specific conditions found in oil and gas investment projects. Our instruments meet internationally accepted pressure gauge standards EN 837, EN 13190, IS 3624 and IS 13211 그리고 ASME B40.100—and are produced to operate under conditions involving vibration fatigue cycles, corrosive fluids produced by thermal cycling and variation and extreme duty cycles.
Function of Pressure and Temperature Gauges in Oil & Gas
Gauges provide instant and on-site indications of essential process values. Their main purposes are:
-Monitoring wellhead conditions.
-Monitoring separator and treater performance.
-Confirming pipeline operational limits.
-Assisting in the control of furnaces, heaters and reactors.
-Facilitate safe operations in storage terminals and utility systems.

Applications Across the Oil & Gas Value Chain
- Gauges for Pressure and Temperature at the Wellhead
The wellhead components depend on gauges to measure:
-tubing pressure
-casing pressure
-annulus behavior
-injecting
- Pipelines and Transmission Systems
Utilizing gauges to monitor pipeline burthen and pressure and temperature changes that drive flow characteristics. Capillary-mounted gauges and SCADA linked devices enable remote monitoring.
- Oil & Gas Processing Units
Separators, treaters, dehydration units, and heat transfer systems use stable pressure and temperature indication to maintain process efficiency.
- Refinery and Petrochemical Plants
Gauges are used on:
-crude heaters
-distillation columns
-reformers
-cracking units
-steam and utility lines
Selecting Pressure Gauges for Oil & Gas
Process fluid characteristics:
– clean → Bourdon tube
– corrosive → diaphragm seal
– particulate → flanged diaphragm
Pressure range:
Gauge should run in center of range somewhere between 50–75%
Environmental exposure:
– High vibrations → glycerin-filled gauges.
Accuracy requirement:
Master gauges for calibrating; industrial gauges used in the field.
Choosing Temperature Gauges for Oil & Gas
온도 범위:
-Bimetal for medium temperature range
-Gas/liquid expansion for high temperature ranges or remote indication
Response time:
– Direct mounted is a faster response than capillary
Thermowell requirement:
A thermowell encloses and protects the sensing element from corrosive media, pressure, and flow.
Ambient conditions: Offshore or outdoors may necessitate corrosion protection.
