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 (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 BTL 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 Figure 4-3.

Magnet: Various magnets are available for the BTL7
transducer (See Accessories on page 23).
