Preparing for installation

Installation
Two mounting options are provided:
– Mounting in a hole with internal thread (mounting hole).
– Mounting in a through-hole (without internal thread)
using a mounting nut (see Accessories on page 17).
Installation guidelines
a) Installation in non-magnetizable material
We recommend using non-magnetizable material to mount
the BTL and magnet.

b) Installation in magnetizable material
If using magnetizable material, the BTL 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).

Installation instructions
Hydraulic cylinder: If installed in a hydraulic cylinder, the
magnet should not make contact with the rod. Minimum
bore diameter in the support piston:
Rod diameter
10.2 mm

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

Fig. 5-4: Mounting hole 3/4"-16UNF per SAE J475 O-ring 15.3×2.4
Horizontal mounting: For horizontal mounting with
measuring lengths > 500 mm, support the rod and, if
necessary, screw it on at the end.
Magnet: Various magnets are available for the BTL (see
Accessories on page 17).
Bore diameter D2
At least 13 mm
