The former two types are in essence analog measurements, while the latter is in essence a binary-type measurement, since the sensed quantity is typically the frequency of vibration. Since the resonant-type sensors measure frequency instead of amplitude, they are generally less susceptible to noise and thus typically provide a higher resolution measurement.
According to Guckel., resonant sensors provide as much as one hundred times the resolution of analog sensors. They are also, however, more complex and are typically more difficult to fabricate. The primary form of strain-based measurement is piezoresistive, while the primary means of displacement measurement is capacitive.
