MAG-031A/023A Precision 2-Axis Magnetometer Systems
The Mag-031A/Mag-023A are precision 2-Axis Flux-Gate Magnetometer Systems designed for use in high temperature and high shock and vibration environments for Dynamic Azimuthal scanning applications. When combined with MWD Survey information, the Magnetometer System can be used to accurately log sensor data Azimuthally whilst drilling.
The 2-Axis system consists of two single-axis Magnetometers, a Dual Channel Processing Board and a single Dual Channel Excitation Board. Specified for operation at a continuous temperature of 175°C, and a survival temperature of 185°C, the System operates from single +5V power supply with power consumption of less than 250mW.
