Frequency response
The frequency response of the sensor is determined by its mechanical construction. The seismic mass and the
rigidity of the inner structure is crucial here, as is its construction.
The sensitivity is linear in other areas of the frequency response. The frequency response only increases signifi-
cantly when near the resonant frequency. Since misinterpretations can occur in proximity to the resonant frequen-
cy, the resonant frequency must be correspondingly high.
