Through wall level switches GPLS-25 are intended for liquid (conductive and non-
conductive) level detection on glass or plastic gauge-pipes, tubes and tanks. The
sensor is equipped with high frequency technology,which allows reliable operation
even for sensing of the adherent electrically conductive medium. The sensitivity and
modes (O - normally open or C - normally closed) of the switches can be easily set by
placing magnetic pen on sensitive spot. Output performance - transistor output with
open collector (PNP) or two wire electronic switch (S). This connection is done by
means of two wires directly into a circuit with relay or to binary input of control system.

Prismatic (refracted) electrode, shape-adapted to be attached
to the gauging pipe or other tube. The fixing of the sensor onto a
pipe is provided by plastic straps.
Plannar electrode, suitable for installation on flat surfaces (e.g.
plastic or glass tanks). The sensor can be fixed with plastic straps
or by double sided adhesive layer.
