We are the leading manufacturer, exporter and supplier of RTD Thermocouples – Thermowells.
Thermowells are tubular fittings used to protect temperature sensor installed in industrial processes. A thermowell consists of a tube closed at one end and mounted in the process stream. A temperature sensor such as a thermometer, thermocouple or resistance temperature detector is inserted in the open end of the tube, which is usually in the open air outside the process piping or vessel and any thermal insulation. The process fluid transfers heat to the thermowell wall, which in turn transfers heat to the
sensor. Since more mass is present, the sensor’s response to process temperature changes is delayed. If the sensor fails, it can be easily replaced without draining the vessel or piping. To be representative of the average temperature of fluid, the thermowell must extend a few per cent of the inside diameter of the process pipe or vessel
