Small Volume Quartz Accelerometer

ER-QA-03C(15~50μg)
◆Bias repeatability:15-50ug
◆Factor scale repeatability:15-50ppm
◆Class II non-linearity repeatability:20-30μg/g2

  • 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. 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.
