• Calibration method using transfer function was developed for comparison calibration of vibration pickups in a back to back configuration. The sensitivity of a uniaxial vibration pickup calibrated by this method agreed satisfactorily with that calibrated by a conventional sinusoidal excitation method. In the comparison calibration, best result can be obtained when reference and unknown pickups are mounted in the back to back configuration with sensing axes parallel with the direction of motion. A mounting adaptor is necessary to mount a multiaxial vibration pickup on the reference pickup back to back. However, precision of the calibration decreases, when rocking motion of the adaptor is excited, or the adaptor deforms. Influence of the rocking motion and resonance due to the deformation has to be minimized for the precise calibration. In this paper, two methods in which a reference vibration is estimated from vibrations measured at several points of the mounting adaptor are proposed for the calibration of the multiaxial vibration pickup.
