Abstract
The invention discloses a method for calibrating the sensitivity of multiple sensors. The method comprises the following steps that a plurality of acceleration sensors to be calibrated and a plurality of standard acceleration sensors are fixed above the work surface of a vibrating table and below the work surface of the vibrating table respectively in a back-to-back mode, and the multiple sets of acceleration sensors to be calibrated and the standard acceleration sensors are electrically connected with detection equipment. According to the calibrating method, the acceleration sensors to be calibrated and the standard acceleration sensors are fixed above the work surface and below the work surface respectively in back-to-back and one-to-one correspondence modes, so that when the acceleration sensors to be calibrated are calibrated, the influence of the flatness and the evenness of the work surface is avoided, and the errors of the calibration results of all the acceleration sensors to be calibrated can not happen in the batch calibration process. Accordingly, the calibrating method saves time and labor, and improves working efficiency.
