To achieve high-precision micro acceleration measurement
a measurement system based on quartz flexible accelerometer is proposed. The measurement precision of the accelerometer is effectively improved by magnetic shielding structure and multi-level precise temperature control
and high-precision current measurement circuit is designed for acquisition of accelerometer signal. The experimental results show that this system has advantages of high measuring precision
large measuring range and real time
which can meet requirements of highprecision low acceleration measurement.
