big measure range quartz accelerometer high reliable flexure accelerometer
A quartz accelerometer is a force equilibrium sensor,a precise instrument designed according to the principle of ineria.The acceleration input is converted to its fracture's subtle displacement,and then balanced by a feedback force.As a force feedback loop is used,the accelerometer has the features of high precision,high shock resistance,broad measurement range and excellent overload capacity.It is one of the most essential devices in the inertial navigation and guidance system.A quartz accelerometer consists of a gauge head.an excitation circuit and a frequency measurement circuit.The gauge head consists of a dampling plate,a metal pendulum and a force sensitive quartz stick.
