Thermowells / Pockets

Browse our range of thermowell and thermowell pocket sensors for a range of applications and industries.

What is a Thermowell?

A thermowell is used to protect temperature sensors such as thermocouples, thermistors and thermometers against damage from excessive pressure.

A pocket sensor is a cylindrical fitting with a tube closed at one end and mounted on the wall of the piping or vessel.

What are Thermowell Pockets Used For?

A thermowell pocket is a protective enclosure or tube installed in industrial processes to house temperature sensors, such as thermocouples or resistance temperature detectors (RTDs).

Temperature probe pockets provide a barrier between the sensor and the process fluid, ensuring accurate temperature measurement while protecting the sensor from harsh conditions or corrosive substances.

Thermowell Pocket Sensors by Process Parameters

At Process Parameters, we offer custom-built, high-quality thermowell pockets to suit your thermocouple or platinum resistance thermometer with a simple design. Choose your pocket diameter, pocket length and thread type and we’ll do the rest.

Our design of temperature sensor pockets is manufactured with 316 stainless steel and suits other temperature sensors such as dial thermometers, rod thermostats and bimetallic gauges.
