MECHANICAL ACCESSORIES

Thermowells, informally known as sensor pockets, are hollow on the inside so you can insert a temperature probe. Typically, either cable probes or mineral insulated probes are used.

A thermowell is a good choice wherever temperature probes have to be changed during running processes. This is not only important in case of repair, but also when a probe has to be calibrated regularly. The thermowell ensures the tightness of the system, so you can easily remove and replace the temperature probe. This works during the running process and without emptying any circuit. 

At the same time, the thermowell also protects the temperature probe and extends its service life. Because with a thermowell, you achieve greater mechanical stability and pressure resistance. Some of our customers use thermowells to ensure superior sealing – especially when dealing with creeping liquids such as silicone oils. 

Please note that the use of a thermowell increases the response time of the temperature probe. The measuring system is therefore more sluggish than without a thermowell. This is not necessarily a problem but it can be. 

The typical thermowell is made of stainless steel and has a 1/2″ thread. We manufacture thermowells for you in different diameters, lengths and with different process connections (flanged, with feed-through connections, etc.). Get in touch with us now. We will find the right thermowell for your requirements!
