TC Ltd for Temperature Measurement & Control

Oil and Gas Industry

ATEX, IECEx or EACEx Approved Temperature Sensors, Instrumentation and Accessories

TC Ltd manufacture and supply a range of ATEX, IECEx or EACEx approved thermocouples and RTD Sensors along with a range of complementary instrumentation, temperature transmitters and accessories specifically designed for use within the Oil and Gas Industry.


There are many processes within the Oil and Gas Industry such asthe extraction, production, refining and distribution of multiple petrochemicals which require a diverse range of temperature sensors.



TC specialise in manufacture a wide range of thermocouple and RTD Pt100 sensors for Oil and Gas applications including down hole, multipoint, flare stack, tank monitoring with the use of a thermowell, tube skin and various other surface temperature sensors all of which can be supplied with ATEX, IECEx or EACEx hazardous area approval.

Accessories include single and multicore thermocouple cables, connectors, compression fittings and temperature transmitters and instrumentation.
