TY - JOUR AU - Ishigami, Tamio AB - This paper describes a practical calibration method considering the base strain of vibration pickups. Generally the base strain occurs at a connecting surface to be fastened each other and is an important factor influencing the sensitivity of the pickups. The authors have experimentally examined whether the sensitivity about one of the pickups to be calibrated is different or not between both measuring arrangements, that is, comparison calibration and actual vibration test. According to the experiment, the sensitivity in the arrangement of actual vibration test is higher by 4 % than that of comparison calibration even if it depends on base strain. A primary calibration by a laser interferometer system is also performed with high accuracy in this paper. The experimental results show some difference of the sensitivity between different arrangement methods of the pickups.
