Measurement Techniques Aims and scope

Conclusions

  1. 1.

    It is advisable to employ moving coil transducers having a resonant frequency no less than 15 to 25 Hz in the design of middle frequency (7 to 400 Hz) vibration measuring instruments.

  2. 2.

    The correction of the characteristics of such instruments that is necessary in order to operate over the entire frequency range cited can be accomplished both by passive electrical compensation and with positive displacement feedback.

  3. 3.

    Passive electrical compensation is a more universal method of transforming the characteristics but when it is used, it is difficult to make transducers interchangeable. The application of positive displacement feedback is advisable for the construction of multichannel vibration measuring instruments.
