High precision quartz flexible accelerometer HQA-T series
Miniature volume ! Independent creative technology!
From the servo-circuit production to assmble the sensors at one-stop .
1.HQA-T Series High Temperature 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 high accuracy navigation system of aerospace and oil drilling inclinometer or geological exploration system.
