Mechanical mounting of vibration acceleration sensors
Vibration acceleration sensors must be mounted on the machine in a way that the vibrations
that are needed for the machine diagnostic are measurable.
Picture 19: Sensor positions with an example of 3 shafts
Generally there are ideal measurement points that can be deduced from the concrete
constructive conditions. Normally these positions are chosen by a mechanical engineer or
machine diagnostician. Picture 19 shows the recommended sensor positions for two vibration
acceleration sensors of a two-stage gear drive.
Depending on the intended sensor positions the vibration acceleration sensor with angled or
straight connection cable has to be preferred.

The permanent mounting of a vibration acceleration sensor can be done by a screw connection
or by a glue connection. For both connection types it is required to have a smooth and flat
surface. There should be no color or rust on the contact surface.
