Electrode relay for conduct.level switches NE-104,-304

KOBOLD electrode relays of model NE- are used with conductive level switches NES, NEH, NEW and LNK for level monitoring and control of conductive liquids. An electrode relay NE-104 is required for single point signalling. It posses additionally a bi-stable interval relay which lock and is therefore suitable for pump control.

With relay NE-304 and a level conductive switch with  two signal and one ground electrodes, two level limits could be detected. The relay outputs could be configured as a Min. / Max. control or as a single limit switch.

The relay NE-204 is used together with the conductive level limit switch NEW for water contaminating liquids. It should be used for tanks and vessels for storage of non-flammable, water contaminating liquids.
