Series Description

The Precon ST-L* Series Thermistor and RTD Ring Lug Sensors provide precision equipment temperature sensing for building automation systems. The active sensing element is made of a highly stable, precision thermistor material or platinum RTD. The ring lug design allows the sensor to be mounted to a bolt or stud to monitor equipment temperature. A common use is to monitor motor winding temperature by mounting to the motor housing. It comes in sizes to accommodate 1/4 in , 5/16 in and 3/8 in studs or bolts.
