Product Description
Level sensor for measur-
ing the level of conductive
liquids, i.e. max./min. control
of charging or discharging.
The function is determined
by the amplifier relay used.
The sensors are delivered
with standard length elec-
trodes - these are cut off to
suit the application.

Mode of Operation
The length of the elec-
trodes determines the levels
which will be detected and
the amplifier chosen deter-
mines the function (see SV...,
S195/196, S1961, ELA, ELC
or ELD). If the container is
made of a conductive mate-
rial this can be used as com-
mon electrode.
