2.2.6 The Measuring Point

Preferred measuring location is the place where the shock impulse signals can
be received with the least loss. In the case of machinery with rotating masses,
the bearing or the bearing enclosure are the ideal measuring locations.
Four rules for the selection of a measuring point
1. Material Transition
Every additional material transition dampens and/or reflects the signal to be
measured. The signal path should have one material transition maximum,
between bearing and bearing enclosure.
Fig. 2.2.6-1: One material transition
Note
Signal losses due to addition material transitions can be significant (i.e.,
partition lines).
