3 REMOTE SENSOR
When an installation requires that the electromagnetic sensor is separated from the
control unit, the union between these two elements must be made by means of an
interconnection cable.
Normally, these cables are supplied by Tecfluid S.A., already prepared for their direct
connection to the sensor and the converter.
Important: The interconnection cable between the sensor and the converter must always
be a single piece, without any kind of joint.
In the event of having to repair a broken cable at one of its ends, it should be cut at the
breakage point and reworked for the connection at that point.
3.1 Preparing the cable
The ends of the cable should be prepared as shown in the drawing on next page. Special
care should be taken to avoid possible short circuits between the shields. The point at
which the shields are cut refers to the aluminium shields.
Electronics side
At the electronic unit’s end, the ends of the cables should be striped at about 5 mm and
then tined. Pair 1 (Red & Black) is for the excitation coils and Pair 2 (White & Black) is for
the electrodes.
Sensor side
Pass the sensor side end through the cable gland of the sensor connector and then
connect the cables of this end to the IDC connectors as shown in the following drawing.
(the unión between terminals 2 and 4 in Pair 2 must be taken into account).
