    ER-QA-03B Wide-Range Quartz Accelerometer 


    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.
