Fluxgate Magnetometer
Compared with the magnetic field measuring instruments based on the principle of the Hall effect or magnetoresistance effect, it is the best choice for measuring weak magnetic fields. It has digital and Analog signal output, a unique CAN bus network interface is suitable for multi-array magnetic field testing, widely used in scientific research, the military industry, aerospace and other departments.
Dexinmag series fluxgate magnetometers include a main unit and a fluxgate probe sensor, a 15-core cable connects the probe and the electrical unit. The electrical unit provides the control signals to drive the probe and processes the signal output from the probe. It also includes an electrical section for switching and setting ranges. 5 The digital color screen displays the measured magnetic field value, and the dual-channel connector outputs the analog value and digital signal of the measured magnetic field.
3-axis fluxgate magnetometer probes can be selected from imported and domestic one-dimensional probes. Longitudinal probes measure the component of the magnetic field along the length of the probe. Transverse probes measure the vector component across the width of the probe. Both probes are capable of measuring the three vector components of the magnetic field by measuring the three orthogonal axis magnetic fields.
