NIVOCONT K level switches, based on the conductivity principle, can be applied to liquids with conductivity higher than 10-5 S/cm.
For detecting the level, probes are immersed into the tank. These probes (and the tank wall if conductive) serve as contacts of an electric circuit.
Probes can be of single or multiple rod versions. A maximum of 4 probe rods can fit in the multiple probe socket with an additional reference probe if tank wall is not conductive.
The probe length should be in accordance with the level to be detected. When the liquid level reaches the probe, it will create a short-circuit and the output relay will be activated. The device senses the conductivity difference between the probes and the reference probe. The KLP separators should be used at every 0.5 m to provide suitable distance between the probes.
