    Introduction

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

    Introduction

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

    Applications 

    MWD tools

    LWD tools

    Inertial navigation

    Oil well logging

    Gyro inclinometer

    Guidance and control
