Electrode relays and contact protection relays

The electrode relays are used for conductive level detection. levels. The possible applications extend areas where conductive, liquid media are to be detected, controlled to be detected, controlled or regulated. Hereby level detection (overflow / dry run) as well as minimum / maximum as well as minimum / maximum controls can be realised. The contact protection relays are universal measuring transducers, which input signals (resistance values) with "Namur" specification (DIN EN 60947). Namur" specification (DIN EN 60947) into switching signals of floating output contacts.
