This dew point sensor was developed in conjunction with an alre dew point monitor (e.g. WFRRN) or cooling ceiling controller (e.g. (KTRRB, KTRRU, KTRRUu, KTRVB, KTFRx) specifically to detect and report the dew point. When installed correctly, it prevents condensate dripping from the cooled parts of the cooling circuit. Use: Pipes transporting cold water, plaster cooling ceiling with capillary tube system. Installation/fastening is done using clips on the cooling ceiling capillary tube or with cable ties on the pipe. Sensor cable can be extended up to 50 m with 2 x 0.5 mm².
