Precon Stainless Steel Sheath Thermistor and RTD Sensors ST-R*S, ST-R*SC Series

Precon Stainless Steel Sheath Thermistor and RTD Sensors

 

The Precon ST-R_S, ST-R_SC Series Stainless Steel Sheath 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. Each sensor has a sensing element that is ruggedized and sealed with a thermally conductive compound in a versatile 3" (7.6 cm) long stainless steel tube. The probe is waterproof, and the sensor is ideal for use in refrigeration cases, or as a strap-on sensor for pipes. The thermistor operating range is -30° to 230℉ (-34° to 110℃). The RTD operating range is -68° to 240℉ (-55° to 116℃). The Model ST-R_S Stainless Sheath Sensor is suitable for direct application to pipe surfaces for chilled or hot water measurement. It is also used for freezer cases where moisture protection is important. This rugged strap-on sensor comes with an 8-ft (2.4m), 24-gauge zipcord lead. The Model ST-R_SC Stainless Steel Sheath Sensor comes with a rugged 25-ft (7.6m) cable when ordered with the &#8243C&#8243 option. The 25-ft (7.6m) cable allows for termination away from areas of condensation. It is an ideal choice for freezer case applications.
