Abstract:
To improve the performances of sensors,the sensitive components in differential-type are optimally designed with Fe-based amorphous ribbon as the sensitive material and the longitudinal excitation as the driving mode.The pulse excitation circuit,peak-value detector,passive low-pass filter circuit and voltage follower are designed to match up with the structure and the driving mode of the sensitive material.The static and dynamic performances of the accelerometer prototype based on the giant stress-impedance(GSI)effect are experimentally calibrated and analyzed on data.The test results show that in the acceleration field of ±50 g,the sensitive is 34.81 mV/g,the linearity error is 0.56%,the repeatability error is 2.67% and the hysteresis error is 0.87%,which attains the requirement in actual measurement of accelerated velocity.
