10.4 Frequency range
Because of their mechanical quality, piezoelectric sensors
have very low damping. The useful frequency range is
limited in the upwards direction by the increasing
resonance rise.

= Amplitude ratio
The following approximate values apply to the amplitude
error or achievable accuracy as a function of frequency:
Accuracy 10 %  f
max
≈ 0,3 · natural frequency
5 %  f
max
≈ 0,2 · natural frequency
1 %  f
max
≈ 0,1 · natural frequency
