Water sensors Rettberg 134065000 and others .
The LWW 20 water sensors monitor the supply of cooling water (for example, for a distillation cooler) through a platinum relay switch at the outlet (10 mm pipe connection) of the device. The switch is connected to the relay via a cable (5 m long). When registering a shortage of cooling water, the relay turns off the heater. In this case, an audible and visual warning signal is given.
