The sensor can only function correctly, if all rollers of the sensor contact the tube continuously
during the measurement.
Due to the rollers, the gap between sensor element and tube results automatically.
It has to be considered, that a strong magnetic field is generated while measuring. Magnetic steel
must not be present within a distance of 5 cm to the sensor head (guide rollers of the sensor).
The same also meets the rear of the material (inside of tube). It must be free from any metallic
matter (especially support rollers, tapered guidance or mandrels*).
During detection the sensor must continuously contact the tube. Therefore the sensor bracket must
be equipped with rubber mounts, so that the sensor can evenly contact the tube.
As rubber mounts the following can be used (e.g.):
Model: Rubber mounts Type B, (see "technical data", rubber mounts D=30mm, H=25mm).
The rubber mounts are included in the scope of supply.
