ICP® BASED REFERENCE ACCELEROMETERS

Mark I. Schiefer, Jeffrey Dosch

Abstract

ICP® based accelerometers have become widely used in the field of vibration measurement as general purpose sensors. Charge mode accelerometers have historically been used as the reference for back to back comparison calibrations. This paper introduces the concept that the use of properly constructed ICP® based accelerometers result in a much simpler, more reliable and easier to use calibration system than charge mode accelerometer based systems. Historical data will be provided which documents the long term stability of selected ICP® reference sensors. This paper is relevant to anyone evaluating or assessing both secondary and primary accelerometer calibration system performance.
