Dew point monitor, 24 VAC/VDC, changeover contact
Electronic dew point monitor with standard rail mounting for detecting and reporting the dew point. If the dew point sensor (TPS 1, 2, 3) is installed correctly, it prevents dripping condensation 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 over in the event of condensation. This contact can be used for direct interruption of cooling or for indirect interruption of cooling by signaling to a building management system. If the optimum installation location cannot be clearly defined, it is possible to connect up to 5 dew point sensors to the monitor in parallel. The activated function “Cooling interruption due to dew point triggering” is indicated by a red lamp on the device. The switching point is fixed at approx. 98 % r.H.
