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.

Applications

Flight control

Stabilization

Aircraft navigation systems

Attitude heading reference systems (AHRS)

Ground vibration testing (GVT)-wind tunnel testing
