Level Monitor for conductive liquids, 4 Levels, 6 Programs, sensitivity adjustable, Housing Design V6 for circuit-breaker box
The NS level monitor is an electronic device for monitoring levels of conductive liquids. The monitoring of the levels is effected vis electrodes, which are dipped or set free according to liquid level. All conductive liquids can be monitored, preferrably, however, water, also of different degree of hardness.
To adapt the relay to the conductivity of the liquid and to the capacitance of (long) cables, the switching limit can be adjusted app. 5 kΩ ... 250 kΩ. Thus it also is possible to tell between the liquid and foam over the liquid.
The NS unit protects aggregates and plants against dry running, overflow, leakage damages and unnecessary loss of liquids. It controls and monitors levels of liquids in waste-water, pools, fish farms and whereever a certain level should be maintained or dosed.
Depending on the application and the set program, it controls the level between 2 or 3 electrodes by means of opening or closing dose or drain of a container. The top and the lowest electrode protect from overflow or running dry.
An electrolytic corrosion of the electrodes as well as detonating gas production is excluded due to a AC current measuring path.
The universal supply voltage AC/DC 24-240 V allows to connect the relay to any common mains.The isolation between electronics (= electrodes) and supply voltage avoids malfunctions caused by potential spreading, also at DC-supplys.
