HQA-J1TR Quartz-Flexible Accelerometer is a single-axis torque reaction type accelerometer to detect the external acceleration signal by detecting quality,and then demodulated and amplified by the servo circuit, and finally output current signal proportional to the acceleration signal. It is widely used for a high accuracy navigation system of aerospace.
