RTS Wall and Bead Sensors

The room temperature sensor provide precision room temperature sensing in a discreet button form factor for all popular DDC systems.

This temperature probe is suitable for a variety or high temperature applications such as floor heating, solar heating systems and domestic hot water heaters to name a few. The sensor element is housed in a stainless steel probe which is 6mm diameter x 50mm [2in] long. The cable is 4.5 meter long and is a high temperature material that is tough and highly durable.The probe is available with custom thermistors  and Pt elements, nearly all the popular ranges are available with very small minimum order quantity.

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 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.
