Electronic dew point monitor with standard rail fastening for detecting and reporting the dew point. If the dew point sensor (TPS 1, 2, 3) is installed correctly, it prevents condensate dripping from the cooled parts of the cooling circuit. For this purpose, a dew point sensor located at a suitable point on the cooling circuit is evaluated and a potential-free changeover contact is switched when condensation occurs. This contact can be used to directly interrupt the cooling or to indirectly interrupt the cooling by reporting to a building management system. If the optimal installation location cannot be clearly determined, it is possible to connect up to 5 dew point sensors to the monitor in parallel. The activated cooling interruption due to dew point triggering function is indicated by a red lamp on the device. The switching point is fixed at approx. 98% rH.
