A New Digital Closed-Loop Control Accelerometer

Abstract:

A digital closed-loop control quartz accelerometer with new structures is performed, which overcomes the disadvantages of restriction of measurement range and sensitivity of QVBA (quartz vibrating beam accelerometer). It has not only the same precision as QVBA in theory, but also large measurement range without reducing the sensitivity. The accelerometer is proposed to be used in large range and high-precision measurement of acceleration.
