Magnetizable material
If using magnetizable material, the transducer must be
protected against magnetic interference through suitable
measures (e.g. spacer ring made of non-magnetizable
material, a suitable distance from strong external magnetic
fields).

4.2 Preparing for installation
Installation note: We recommend using non-
magnetizable material to mount the transducer and
magnet.
Horizontal assembly: For horizontal assembly with
nominal lengths > 500 mm, support the rod and tighten it
at the end if necessary (only possible with a diameter of
10.2mm).
Hydraulic cylinder: If installed in a hydraulic cylinder,
ensure that the minimum value for the bore diameter of the
support piston is complied with (seeTab. 4-1).
Fitting bore: The mounting surface of the transducer
housing must make full contact with the supporting
surface. A suitable O-ring must completely seal the bore,
i.e. the countersink for the O-ring must be produced in
accordance with Fig. 4-3.

Magnet: Various magnets are available for the BTL7
transducer (See Accessories on page22).
