Product Description
Ordering Key
VTI 4
Level sensor for measuring
the level of conductive li-
quids, i.e. max./min. control
of charging for 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. The teflon hous-
ing makes the sensor excel-
lent for use in rough environ-
ments.

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.
