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).

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.
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 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 according to Fig. 4-3 and
Fig. 4-4.

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