0.250″ (6.35mm) spring-loaded sanitary sensor for thermowell applications. Available as an RTD or thermocouple.

The S65 spring-loaded sensor is designed to be used with the SWE sanitary elbow thermowell or the SWT standard sanitary thermowell. The hygienic ferrule extension connection provides a quick and easy way to remove the sensor for calibration and process verification while eliminating the NPT threads normally used with a thermowell.
