XW-AS1920 Family Quartz Accelerometer |
|
A quartz accelerometer is a force equilibrium sensor, a precise instrument designed according to the principle of inertia. 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.
■ Broad measurement range
■ High precision
■ Excellent overload capacity
■ Small volume
■ Low power
■ Low cost
Measurement of various types of linear acceleration, vibration acceleration. Measurement of parameters such as speed, distance, angular velocity, angular displacement. It has been successfully used in the following aspects: satellite microgravity measurement system, high precision inertial navigation system, geotechnical foundation drilling measurement, as well as petroleum drilling, continuous inclination measurement system, carrier rocket, long distance ballistic missile, space ship, midrange missile, tactical missile, military aircraft, ship.
