The stainless steel housings of the Water-Level
Sensor 20-3 and 20-4 also take on the function of
the common electrode. The minimum and maximum
electrodes are in the housing. The permanently set
level difference is 20 mm. In addition the 20-4 has a
dry-run protection electrode.
It can be retrofitted with a dry run protection elec-
trode. The electrodes can be adjusted according to
the level differences via the cable length. They give
switch on and switch off commands to regulate the
water level or to protect the pump technology (Sup-
plemental electrode 2000-1).
