Abstract

National Institute of Metrology (Thailand), NIMT has two primary accelerometer calibration systems, old and new systems, using methods according to ISO16063-11. The differences between both systems are the calibration methods and the moving direction of exciter. This paper presents the comparison for charge sensitivity of standard accelerometer between two systems in order to investigate the effects of calibration methods and moving direction of exciter on the calibration results, to confirm the capability of the new system and to provide a link between two systems. Also the comparison results at the frequency range of 40 to 5,000 Hz are illustrated.
