Precon Stainless Steel Flush-Mount Thermistor and RTD Sensors ST-S Series

Precon Stainless Steel Flush-Mount Thermistor and RTD Sensors

 

The Precon Model ST-S Stainless Steel Flush Mount Sensor from PreCon provides precise room temperature sensing for Building Automation Systems, BAS, and HVAC applications. The active sensing element is made of a highly stable precision thermistor material or Platinum RTD. This material is ruggedized to provide moisture/vapor resistance and is bonded to a 430 stainless steel plate. The back is insulated to reduce interior wall temperature influence. This sensor is intended for interior use only.
