Thermowells are tubular fittings used to protect temperature sensors installed in industrial processes. A thermowell consists of a tube closed at one end and mounted in the process stream. We currently produce several varieties that house both RTD’s and our Temperature Sensing Capillary Probes.

Clear PVC thermowells are available for unobtrusive sensing of fluid temperatures. These thermowells protrude out of the cavity being monitored rather than inward. Typical installation is for a temperature sensing RTD in a pool or spa where an inward protruding sensor may be damaged or broken. Clear PVC thermowell has a unique design that allows for sensing probe to be positioned out of the fluid stream to prevent damege or breakage of the sensor and thermowell. Material can be sensed 360° around the RTD or probe either stagnantly of by circulating monitored fluid around the sensing chamber. Three through hole sizes include seal, PVC nut and retaining grommet.
