<p>A vibration pick-up with a pressure sleeve is mounted by a mounting element extending through a central opening of the pressure sleeve. The pressure sleeve is clamped with an abutment surface on a component which causes vibrations. A threaded ring with a spring or a welded spring provided on the pressure sleeve holds a seismic mass under the pressure of the spring, and a detection element formed for example as a piezo-ceramic disk is arranged. The pressure sleeve has extensions with depressions which, in combination with a flanged insertion disk, form a seal labyrinth.</p> |
