Conductive Sensors
• Excellent resistance to chemicals
• Teflon housing
• 1 to 4 electrodes
• Isolated (teflon) or unisolated electrodes
• Cable connection
• 1 1/2” pipe thread according to ISO 228/1-Gx”
Product Description
Level sensor for measur-
ing the level of conductive
li quids, i.e. max./min. control
of charging for discharging.
The function is deter mined 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 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.
