Thermopockets (316 Grade)

Stainless steel thermopockets of various sizes, designed for use with industrial style temperature probes
to provide protection for the sheathing from corrosive media, and to facilitate probe replacement
without disturbing the process

What is a Thermowell?

Some temperature sensors can be directly inserted into the process they measure, however, with industrial style temperature sensors, the process is a lot harsher in nature with the potential to cause damage and affect performance. This is when a protection tube called a thermowell is used. This thermowell design consists of a pre-fabricated and welded stainless steel hollow tapered tube which is closed at one end. The diameter of the tube is designed to accept a specific sized probe. The closed end of the tube is inserted into the process and secured in place with a 1/2" BSP threaded A/F hex fitting. This is called the process connection. The temperature sensor, RTD or probe is inserted into the tube and secured in place with a threaded compression fitting. This design enables the sensor to be easily and quickly inserted and removed from the pocket without having to disturb or drain the surrounding media.
