About Thermowells

A thermowell is a pressure-tight assembly that protects a temperature sensor in processing applications where the sensor is not mechanically or chemically compatible with the process environment. Installed directly into the piping systems on process vessels, thermowells allow sensor replacement without the need to interrupt the process flow or drain the process system.
