NivoCONT K series
Contact style level switching for liquids
General
Level switches based on the conductive principle may be applied to liquids having higher conductivity than 2 x 10-5 S/cm.
Probes with length corresponding to required switching levels are immersed in the liquid, which changes conductivity between the probes and either the tank wall or, for multiple probe models, a reference probe. This change in conductivity is sensed and converted into an output signal by the electronics.
Up to four probes plus a reference probe can be used depending on model.
