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.
