Series Description

The Precon Model ST-W Immersion Sensor from PreCon provides precise remote temperature sensing for Building Automation Systems, BAS, and mechanical equipment room instrumentation. The active sensing element is a highly stable precision thermistor material or platinum RTD. The sensing element is sealed with a temperature conductive compound in a 4-7/8 in (12.4 cm) stainless steel tube and brass fitting. A brass thermowell is the standard well provided with each sensor. A Greenfield connector is factory installed for flexible connection. The probe assembly on these immersion sensors are removable for replacement without the draining system.
