Installing the transducer

NOTICE!
Interference in function
Improper installation can compromise the function of the
transducer and result in increased wear.
f The flange surface of the transducer must make full
contact with the mounting surface.
The bore must be perfectly sealed (O-ring/flat seal).
f
►
Make a screw plug hole with thread (possibly with
countersink for the O-ring) acc. to Fig. 4-3 or Fig. 4-4.
►
Screw the transducer with fastening screw thread into
the screw plug hole (max. torque 100 Nm).
►
Install the magnet (accessories).
►
From 500 mm nominal length: Also screw the outer rod
onto the end (only possible with 10.2 mm) or support it.
Suitable nuts for the fastening screw thread are
available as accessories (see page 19).
4.3.1 Installation recommendation for hydraulic
cylinders
If you seal the hole with a flat seal, the max. operating
pressure will be reduced in accordance with the larger
pressurized surface.
If installing horizontally in a hydraulic cylinder (nominal
lengths > 500 mm), we recommend affixing a sliding
element to protect the rod end from wear.
Dimensioning of the detailed solutions is the
responsibility of the cylinder manufacturer.
The sliding element material must be suitable for the load
case, medium used, and application temperatures. E.g.
Torlon, Teflon or bronze are all possible materials.

The sliding element can be screwed on or bonded.
►
Secure the screws so they cannot be loosened or lost.
►
Select a suitable adhesive.

There must be a gap between the sliding element and
piston bore that is sufficiently large for the hydraulic oil to
flow through.
Options for fixing the magnet:
– Screws
– Threaded ring
– Press fitting
– Notches (center punching)
If installed in a hydraulic cylinder, the magnet
may not scrape against the outer rod.
The hole in the spacer ring must ensure optimum guidance
of the outer rod by the sliding element.
