Thermowells - Winters Instruments

Thermowells are cylindrical fittings used to protect temperature sensors installed in industrial processes. They consist of a tube closed at one end and mounted in the process stream. A temperature sensor such as a thermometer, thermocouple, or an RTD is placed in the open end of the tube, which is likely in the open air outside the process piping or vessel and any thermal insulation. Thermodynamically, the process fluid transfers heat to the thermowell wall, which then transfers heat to the sensor.
