Product Description Ordering Key
Level sensor for measuring
the level of conductive li-
quids, 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 electrodes -
these are cut off to suit the
application.

Mode of Operation
The length of the electrodes
determines the levels which
will be detected and the
amplifier chosen determines
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.
