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

Fig. 4-4: Mounting hole 3/4"-16UNF per SAE J475 O-ring 15.3x2.4
Magnet: Various magnets are available for the BTL7
transducer (see Accessories on page 20).
