High Permeability Nanocrystalline Cores for Fluxgate Current Sensor

Nanocrystalline Cores for Fluxgate Current Sensor:

The nanocrystalline cores with High Permeability is applied in Fluxgate current sensor. And Fluxgate current sensor is used to measure the weak magnetic field by the nonlinear relationship between the magnetic induction intensity and the magnetic field intensity of the magnetic core with high permeability under the saturation excitation of the alternating magnetic field. This physical phenomenon is like a door to the measured environmental magnetic field, the corresponding magnetic flux is modulated and generate the induced electromotive force through this physical phenomenon. This phenomenon is used to measure the magnetic field generated by the current, thus achieving the purpose of measuring the current indirectly.

The Advantages of Fluxgate Current Sensors:

Fluxgate current sensors have many advantages. First, it is very responsive and can monitor changes in current in real time. Secondly, its high precision can meet the precise requirements for current measurement. thirdly, it is easy to install and can be placed directly on the wire under test without additional power supply. In addition, the fluxgate current sensor has good linear characteristics and low temperature drift characteristics, and it can work stably under different environmental conditions.
