RTS Wall and Bead Sensors

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.

This sensor is used to measure water temperature of heated or chilled water and other liquids in mechanical systems. The sensor is called an immersion type where the sensor is mounted in a brass or stainless steel thermowell which allows the probe to be removed from the pipe without draining the system and protects the probe.There are four thermistor based models, and one RTD version to provide compatibility with the majority of DDC systems.
