Sanitary sensor with integral 0.188″ (4.7625mm) diameter thermowell. Available as an RTD or thermocouple

The S55 offers a small diameter thermowell and probe assembly ideal for obtaining an accurate temperature measurement in small diameter tubes or where immersion length is restricted. This configuration offers the convenience of a removable spring-loaded sensing element and the functionality of a compact package. Use the S55 in applications that require the removal of the sensing element without opening the process system.
