System
The sensor element is used for all transducers and is made out of a co-extruded, high elastic
plastic.
Due to the hose shaped special profile the internal conductive layers are held at a distance.
However, due to the material used with these specific advantages the conductivity is limited.
The result is that the transducer is operated in combination with a SSZ-controller.
The conductive layers of the sensor element which are depicted in a dark colour in picture 1
can be regarded as non-isolated resistor.
These resistors are provided with connecting wires at the beginning and at the end of the
sensor element. The connecting wires are lead to the controller by either 4-wire or 2-wire
cables.
The „inlet“ of the sensor element which has been depicted as two opposite resistors in
picture 2, is connected to the sensor output 3 and 4 of the controller.

The „output“ is connected to the sensor inputs 5 and 6. Please ensure that the cables are
connected correctly as 3 and 5 or 4 and 6 respectively form a signal path.
Parallel connecting of the transducers is not permitted!
