The RTD sensors listed below are constructed with the CIP sanitary connected cap thermowell, which is then mounted into the process with a clamp and mating sanitary cap. A 3-wire spring loaded RTD element and sheath is then screwed into the back of the thermowell. This construction method allows for easy removal of both the well and/or the sensor assembly. The well and sanitary cap in contact with the process are all ground and polished to a finish that exceeds the 3-A Sanitary Standard 74- . Thermowells are supplied with a surface finish that meets or exceeds 32µin Ra. Surface finishes of 15µin Ra or better are available upon request. The complete assembly provides excellent washdown protection.
