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 (only possible with a diameter of
10.2 mm and 12.7 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).
Mounting hole: The transducer comes with an M18×1.5
(ISO), M22×1.5 (ISO) or 3/4"-16UNF (SAE) mounting
thread. Depending on the version, a mounting hole must
be made before assembly.

Magnet: Various magnets are available for the BTL7
transducer (see Accessories on page 27).
