Inertial Sensor Supplier
ER-QA-03B Wide-Range Quartz Accelerometer for aerospace with wide-range, high accuracy, high reliability is not only used in aviation and aerospace inertial test but also can be used in both static and dynamic acceleration measurement. At the same time, temperature sensor is applied in this accelerometer, users can make compensation to bias and scale factor parameters, in order to reduce the impact of temperature factors.
