Abstract

This paper presents a new system that was developed in the Vibration Laboratory at INMETRO for the calibration of vibration transducers and measuring equipments at low frequencies. The system is based on a long-stroke air bearing shaker and on a data acquisition board. Optionally, a piezoresistive accelerometer or a laser vibrometer can be used as reference transducers. Fully automated calibrations of vibration transducers are carried out in compliance with the international standard ISO 16063-21. Some experimental results obtained with this system will be presented herein.
