Thermometer thermowells are made of thermally conductive material and serve to separate the thermometer from the process. Standard thermowells are made of 304 stainless steel. Other materials are available on request. The use of a thermowell is recommended when a thermometer is to be used in a pressurized system to protect the thermometer against aggressive process media and to allow for replacement of the thermometer without system shutdown. Thermowells have a 1/2” BSP male thermometer connection to accommodate TNS, TNF and DTM series thermometers with union nut fitting styles. Process connections are NPT thread or weld-stub.
