首页>Magnetic Field Measurement>3-axis Fluxgate Magnetometer 
Introduction
The 3 axis fluxgate magnetometer is composed of triaxial fluxgate magnetic sensor, data acquisition module, and upper computer software. The triaxial magnetometer is a kinds of vector magnetometer and output x y z magnetic field results. The fluxgate magnetometer uses mobile power supply or regulated power supply to power the data acquisition module and fluxgate sensor. According to the selected communication mode of the data acquisition module, the whole magnetometer system can communicate with the host computer through network port, serial port, USB port or CAN bus. Finally, the two-dimensional waveform or numerical display of the magnetic field signal in the area to be measured is displayed on the host computer software. The magnetometer has the function of data storage to facilitate the subsequent processing of data test. By professional data processing software, 3D model will be finally got for analysis.
SMAGALL specialize in fluxgate magnetic sensors for geophysics survey for 23 years and designed single-axis fluxgate magnetometer and 3-axis fluxgate magnetometers with features of low cost, low noise, high accuracy. We also developed fluxgate gradiometer which is composed of 2 fluxgate magnetic sensor, low noise six-channel data acquisition module.
Features
Real time display of magnetic field measurement results;
Simple and reliable operation;
Suitable for workplaces with PC.
