The temperature-sensing system includes a precision RTD probe; match-calibrated 4 to 20 mA transmitter in a moistureproof enclosure and flexible cable. It can be filled with cryopreservatives, alcohol, water or ethylene-glycol solutions to emulate the material being processed or stored. Large 1.96 x 1.96" (50 x 50 mm) footprint provides extra stability.
