Can low frequency accelerometers and piezovelocity sensors be used for HFD measurements?
Yes. HFD is a trend based measurement technique. Both sensors will provide outputs in the HFD band. In fact, due to the lower resonance of the low frequency sensor, HFD outputs may appear higher than previous readings from 100 mV/g general purpose sensors. Piezovelocity sensors generally provide lower outputs due to the inherent filtering of the velocity signal.
