RECHNER SENSORS KFI-5-1...ETW Serie Bedienungsanleitung Seite 20

Mounting probe with temperature buffer
It is mandatory to have a galvanic connection between the blue (GND) wire and the earthed con-
tainer (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.

Measuring area (M) non-active range 1 (IB1) non-active range 2 (IB2) non-active
range 3 (IB3) area temperature buffer (TP)
Do not mount the measuring range in the area of the container with changes in
the cross section, like the bottom cone of the container
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.
