RTS Wall and Bead Sensors

This Probe Temperature Sensor comes standard with a 15mm Stainless Steel Temperature Sensor. This sensor is a 10K Thermistor, with an industry standard Type 2 curve.Connected to the end of the Sensor is 2 UL2468 26/2CAWG 105°C Black Wires with tinned ends.

This sensor is used to measure the outside air temperature to allow the DDC system to coordinate the mechanical systems with actual building load conditions, enabling such strategies as free cooling, optimum start/stop, and supply temperature reset. The housing is made from PVC and stainless steel fittings which shield the probe from direct sunlight. There are three thermistor based models, and one RTD version to provide compatibility with the majority of DDC systems.

The temperature sensor is designed to measure outdoor air temperature in typical HVAC applications. Mounting is quick and easy using two screws and no electrical box. The thermistor is a well sealed stainless steel probe which is then inserted into a hard rubber PVC radiation shield. The cable is two meters long which allows terminating inside the building in an electrical enclosure or with flying leads. The cable can exit directly behind the probe and into the building through a hole, or it can exit vertically and run down the wall. A foam backing seals the hole in the wall if there is one and also serves to thermally insulate the probe from the wall. The probe is filled with thermal grease for quick response.
