PRIMARY CALIBRATION OF REFERENCE STANDARD BACK-TO-BACK VIBRATION TRANSDUCERS USING MODERN CALIBRATION STANDARD VIBRATION EXCITERS

Following, and in addition to a number of papers, exercises and thorough research concerning the topic of primary calibration of back-to-back vibration transducers in the frequency range >5kHz, this paper aims to raise the question if the conventional method using slotted mass, is mandatory when using modern commercial calibration standard vibration exciters in fully optimized system setup. Detailed description of the exercise and comments, also on phase measurements will be given. Keywords: vibration, calibration, interferometry, dissemination.
