ER-QA-03C Small Volume Quartz Accelerometer For Aerospace
Introduction
ER-QA-03C Small Volume Quartz Accelerometer For Aerospace is a smaller volume quartz accelerometer, not only it can 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, the user can use it to make compensation to Bias and Scale factor parameters, in order to reduce the impact of temperature factor.
