What does a fluxgate magnetometer do?

The fluxgate magnetometer is a high-precision, high-resolution, fully intelligent instrument used to measure the strength of weak magnetic fields (static magnetic fields and low-frequency vector magnetic fields).

Parameters of fluxgate magnetometers

Applications of fluxgate magnetometers

What is the working principle of the fluxgate magnetometer?

The fluxgate magnetometer consists of a host unit and a fluxgate probe.
The host unit provides control signals to drive the probe; the probe measures the vector components of the magnetic field of three orthogonal axes, analyzes the magnetic field angle and vector synthesis value; the host unit processes the signal output by the probe and then displays the measured magnetic field value on a 6-digit digital color screen.

Features of fluxgate magnetometer?

Dexinmag series fluxgate magnetometers have the characteristics of high stability, high linearity and accuracy, and full digitalization. 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, military industry, aerospace and other departments.
