    ER-QA-03B Wide-Range Quartz Accelerometer 

    Introduction
    ER-QA-03B Wide-Range Quartz Accelerometer for aerospace with wide-range, high accuracy, high reliability, not only can be used in aviation and aerospace inertial test but also in both static and dynamic acceleration measurement. In addition, the accelerometer uses a temperature sensor, which the operator can use to compensate bias and scale factor parameters to reduce the influence of temperature factors.

    Feature
    As one of the reference values for selecting quartz accelerometers, ER-QA-03B not only meets the demand for wide range, but also guarantees  bias repeatability and scale factor repeatability compared with other accelerometers with similar range.

    Applications
    Flight control
    Stabilization
    Aircraft navigation systems
    Attitude heading reference systems (AHRS)
    Ground vibration testing (GVT)-wind tunnel testing
