ER-QA-03B Wide-Range Quartz Accelerometer For Aerospace


Introduction

ER-QA-03B with wide-range ,high accuracy, high reliability, not only 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.
