Installing the transducer

NOTICE

Interference in function

Improper installation can compromise the function of the
transducer and result in increased wear.

►

The mounting surface of the transducer must make
full contact with the supporting surface.

►

The bore must be perfectly sealed (O-ring/flat seal).

►

For secure fastening, tighten the transducer with

cylinder screws (ISO 4762, M6 × 16 - A2-70) at all

6 mounting holes.

►

All screws must be tightened with 3.5 Nm.

►

Install the magnet (accessories).

►

From 500 mm nominal length: support the rod and

tighten it at the end if necessary (only possible with a

diameter of 10.2 mm).

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 slide element

to protect the rod end from wear.

Dimensioning of the detailed solutions is the

responsibility of the cylinder manufacturer.

The slide element material must be suitable for the

appropriate load case, medium used, and application

temperatures. E.g. Torlon, Teflon or bronze are all possible

materials.

Example 1, transducer installed with slide element

The slide element can be screwed on or bonded.

►

Secure the screws so they cannot be loosened or lost.

►

Select a suitable adhesive.

Flow gap

Fig. 4-5: Detailed view and top view of slide element

There must be a gap between the slide 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

should not make contact with the rod.

The hole in the spacer ring must ensure optimum guidance

of the rod by the slide element.

Fixing of magnet

An example of how to install the transducer with a

supporting rod is shown in Fig. 4-7 on page 12.
