Electrode relay with ATEX
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.
