High-precision pendulous accelerometer

摘要

Provided is a quartz pendulous accelerometer including a quartz meter configured to sense an acceleration signal, convert the acceleration signal into an inertia torque, and convert the inertia torque into a quartz meter output signal; a readout apparatus configured to convert the meter output signal into an input signal recognizable by a pulse generating apparatus; and a pulse generating apparatus configured to perform control algorithm conversion, oversampling and digital quantization on the input signal to obtain a quantized current pulse, which is converted into an electromagnetic pulse torque for balancing the inertia torque.
