Abstract

This paper discusses the calibration of IEPE accelerometers. The use of these low-impedance output transducers is growing fast worldwide and therefore the demand for their calibration is increasing proportionally. Since many secondary calibration laboratories are more experienced with calibrating high impedance charge output accelerometers, we frequently receive questioning about how to properly calibrate the IEPE models. Some experimental results are presented herein and the effects of some sources of error that can be present during a calibration process are discussed.
