This document specifies the calibration of vibration transducers with built-in calibration coils in laboratory and in situ. In laboratory, the method described can be applied to calibrate the vibration sensitivity and electrical sensitivity, and to obtain the coefficient of calibration coil. In situ, it can be used to calibrate the electrical sensitivity and vibration sensitivity using electrical instrumentation.
This document specifies the instrumentation and procedure for performing calibrations of vibration transducers with built-in calibration coils in the frequency range typically from 0,1 Hz to 100 Hz.
The expanded uncertainty can be evaluated using the method given in this document
