Product Introduction

Quartz flexible accelerometer is a precision instrument comprises quartz glass flexible support and advanced servo circuit based on the principal of inertia. When the carrier is subjected to acceleration, the output of the accelerometer is precisely proportional to the input acceleration. Our accelerometer has a current output form of high output impedance, and users can choose the sampling resistance according to their requirement without affecting the stability of the system.

At present, our quartz flexible accelerometer has formed a series of products, types from the high-precision μg GSACC111Q accelerometer for satellite microgravity measurement to low-cost, anti-harsh environment GSACC117Q accelerometer, as many as dozens, and widely used in aerospace, aviation, navigation, ship, vehicle, petroleum, geotechnical engineering and other fields, providing signals for navigation, guidance, control, leveling, monitoring and other systems.
