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: Drywall cooling ceiling (plasterboard) with capillary tube mat applied, metal cooling ceiling with integrated capillary tube system. Installation/attachment is carried out using clips on the cooling ceiling capillary tube. Sensor cable can be extended up to 50 m with 2 x 0.5 mm².
