Mounting
It is mandatory to have a galvanic connection between the blue (GND) wire and the earthed container
(or additional electrode)! With non-metal containers the connection to the BE electrode is made by
means of a direct cable connection to the blue wire of the cable.
The probe can also be installed up-side down.

range 3 (IB3)
The measuring range must not be mounted in the area of the container where
there is a change in the cross section; for example the cone.
The probe can be mounted in the centre of the container or just off to one side. For a measurement to be independent of the
filling cone, we recommend that the probe be mounted at ¼ of the diameter. The minimum distance between the end of the
measuring range and the container’s lid is 50 mm.
Connect the BE direct to the
blue wire of the cable.
