Introduction

ER-QA-03D Anti-shock and High-Temp Quartz Accelerometer for Oil and Gas

Introduction
ER-QA-03D Anti-shock and High-Temperature Quartz Accelerometer for oil and gas with high-temp, strong anti-shock and high reliability performance, not only it can be used in aviation and aerospace inertial tests but also can be used in both static and dynamic acceleration measurements. 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.

The products are widely used for aerospace inertial navigation, guidance and control, industrial measurement and for measurement-while-drilling (MWD) in oil and gas fields.The problem of azimuth orientation in MWD technology is particularly prominent. The high temperature environment, accompanied by strong vibration shock, is a difficult problem to overcome in MWD. ER-QA-03D is temperature of operating at -55~180 ° C, with an input range of ±30g, bias repeatability <50μg, and scale factor repeatability <80 ppm.

Applications
MWD tools
LWD tools
Inertial navigation
Oil well logging
Gyro inclinometer
Guidance and control
