ZITN 135°C/160°C /185°C HQA-T Series High-Temperature Quartz Flexible Accelerometer is a uniaxial torque feedback accelerometer. It detects the external acceleration signal of the mass, which is then demodulated and amplified by the servo circuit, outputting a current signal proportional to the acceleration signal.
ZITN 135°C/160°C /185°C HQA-T Series High-Temperature Quartz Flexible Accelerometer is widely used in high-precision navigation systems for aerospace, oil drilling inclinometry systems, and geological exploration systems.
