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).
