RTS Wall and Bead Sensors

This sensor is used to measure the supply and return temperature in HVAC system. The flange mount design makes it easy to install the sensor in tight quarters. There are several sensor elements to choose from which guarantee compatibility with all popular DDC systems. The probe in the photo is our standard model which is always in stock, it has a 8″ probe and a 120″ cable, and employs either a precision thermistor or platinum film sensor, so field calibration is not required. The 10ft(3m) cable is “Plenum Rated”.

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.

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.
