4.1.3 Vibration measurement
Vibration is measured inside the BCM housing.
Measurement is based on MEMS technology. The BCM
detects acceleration in three axes. The alignment of the
axes is depicted in Fig. 4-3.

Example BCM installation sites for vibration measurement
At positions subject to wear (e. g. due to friction), it is also
recommended to measure the contact temperature as this
is an indication of wear.
To achieve the best results, the BCM should be installed as
close to the machine element to be monitored as possible.
Since direct installation is not always possible, care should
be taken to ensure that the position properly reproduces
the vibrations and that these vibrations are not falsified by
local resonance or amplifications. The use of a cover hood
or a non-rigid installation position may lead to minimized
accuracy.
During monitoring of linear movements, make sure that
one axis of the sensor is aligned in the direction of the
main force.
One of the axes for each rotary system must be aligned
axially, tangentially and radially.
For installation, ISO 20816-1 and ISO 5348-07
are to be observed.
