Precon Encapsulated Thermistor and RTD Sensors ST-R*, ST-R*R Series

Precon Encapsulated Thermistor and RTD Sensors

 

The Precon ST-R, ST-R_R Series Encapsulated Sensors from PreCon provide precise remote temperature sensing for building automation systems and mechanical equipment room instrumentation. The active sensing element is a highly stable precision thermistor material or platinum RTD. The sensor is encapsulated with a low mass, high conductivity compound for good heat transfer characteristics. It is enclosed in a tough, miniature cylinder, 0.17" in (0.43 cm) diameter, which is small enough to be installed in most HVAC thermostat enclosures.
