Where Are Thermowells Located?

‌Thermowells are commonly installed in pipes or vessels in industrial processes to protect temperature sensors from corrosive media, fluid pressure, and velocity. ‌

Thermowells are cylindrical pressure-tight fittings used to protect temperature sensors such as thermocouples, thermistors, and bimetallic thermometers that are inserted into pipes or vessels in industrial applications. They act as a barrier between the sensing element and the process media, protecting the sensing element from corrosive process media, extending the life of the sensor, and allowing the sensor to be replaced without draining the system, eliminating the possibility of contamination‌.
