Precon All-Purpose Thermistor and RTD Sensors ST-A* Series

Precon All-Purpose Thermistor and RTD Sensors

 

The Precon ST-A Series All Purpose Thermistor and RTD Sensors provide precision remote temperature sensing for building automation systems and mechanical equipment room instrumentation. The active sensing element is made of a highly stable precision thermistor material or platinum RTDs. Each ST-A sensor is a rugged, point-sensitive waterproof sensor featuring a 9" (22.8 cm) 304 stainless steel probe and brass fitting. The brass fitting has a 1/2" NPT male thread. The sensors are supplied with two 1/2" locknuts for easy installation in handy boxes (or other enclosures with 1/2" knockouts).
