Overview and Identication
The Immersion Sensor is made for thermowell mounting and temperature measurement in water pipes, water tanks or
cooling tower sump applications. The rigid probe is made of Stainless Steel and made in different lengths for a custom
thermowell t. The unit is available with multiple thermistor’s or RTD’s as shown in the specications. Enclosure mounting styles come in plastic or metal for both NEMA 1 and NEMA 4 applications and are all plenum rated.
