AS1920 is a high precise quartz accelerometer sensor designed based on inertial principle. It convert the input accelerated speed into infinitesimal displacement and balance by feedback force. The force feedback loop make it own features of super high precision, high anti-interference performance, wider measuring range and high overload capacity. It is the indispensable key part in inertial navigation and guiding system.
