EXAMPLE OF MOUNTING WITHOUT EASY MOUNT

4.1.

Mounting with a rubber foot (F5950)

This mounting allows the sensor to be put straight on a levelled

ground.

The rubber allows to absorb the shocks and the slights

irregularities of the state of the ground surface.

4.2.

Mounting with a solid steel base (A5950)

This combination gives an easy solution for the installation when

the anti-rotation and counter force parts are incorporated to the

structure. The A5950 base has the necessary solidity to support the

head of the sensor and allows it to move freely (in the case of great

dilatation, for example).
