Resistance Temperature Detectors (RTDs) with thermowells are typically used in pressurized or harsh industrial process applications that require the benefits of RTD temperature measurement but require additional protection from the working environment.
The thermowells are manufactured from drilled bar stock and can be designed with a variety of lengths and NPT thread or flange sizes. The resistance temperature detector element is spring loaded into the thermowell for positive contact and rapid temperature response.
Cast iron or aluminum screw cover heads are used to terminate these assemblies. The element construction can be built to withstand temperature ranges up to 1200°F. as well as additional features to prevent premature failure due to excessive shock or vibration.
