DXGM-5 Fluxgate Magnetometer

DXGM-5 Fluxgate Magnetometer

Production introduction

DXGM-5 Fluxgate Magnetometer is a digital relative recorder to continuously measure and record magnetic field D, H, Z changes in the time. The system mainly consists of the fluxgate sensor excitation and analog signal processing circuit, analog-digital conversion circuit, GPS receiver circuit, liquid crystal display circuit, and power supply circuit and other components. The realization of D, H, Z three components of the data collection, processing, storage, observation curve of real-time display, network communications, instrument calibration and other objectives. DXGM-5 fluxgate magnetometer is a digital magnetometer. The instrument moniters the temperature changes of the measuring point while measuring D, H, Z changes. The instrument uses GPS timing, real-time display geomagnetic threecomponent curve. The instrument has absolute measurement and automatic compensation function, with the probe miniaturization, wide band, large dynamic, high sampling rate and large capacity data storage, at the same time with TCP / IP network data communication, USB mobile hard disk storage, low power consumption and temperature Coefficient and other characteristics.It is mainly applied to geomagnetic observation stations.
