Quartz flexible accelerometers are essentially uniaxial torque feedback devices that employ mass detection to identify external acceleration signals. These signals undergo demodulation and amplification through a servo circuit, resulting in an output current signal directly proportional to the detected acceleration. Widely employed in aerospace high-precision navigation systems, as well as in inclinometers for oil drilling and strapdown inertial navigation systems in geological exploration. The key components include a differential capacitance sensor, a detection mass pendulum assembly, an electromagnetic torque device, and an electronic amplifier. Acceleration along the sensitive axis induces a positional shift in the detection mass, which is then detected by a position detector. This signal is subsequently input into the amplifier, activating the force generator to restore the detection mass to its original position.
