The two-channel version is especially
cost-effective. When the five relay
version is used to operate two
measuring points, for example, a
maximum and minimum switchpoint can
be allocated to each channel. The alarm
relay signals any abnormal operation.

Double protection against overfill: all

blocking distance of the sensor, this is
promptly indicated by the display, the
signal output and relays.
