Din rail mounted units for the monitoring and alarming in applications where the presence of water is a problem. Such applications include water contamination of the oil within submersible pumps or water leak detection from pipes within buildings. Working on the conductive probe principle and with an adjustable sensitivity. In a situation healthy condition the output relay is energised, when the presence of water is detected, i.e. in the case of a pump, the seal fails and the oil becomes contaminated the resistance drops. If the resistance falls below the set level as set via the front potentiometer the output relay will de- energise and the red LED will extinguish. A green LED indicates the connection of the auxiliary supply.
