Details:
The magnetic probe utilizes cobalt-based amorphous materials with high permeability and low saturation flux as its magnetic probe element. Under saturation excitation of an alternating magnetic field, the probe measures the magnetic field by measuring the nonlinear relationship between its magnetic induction intensity and the magnetic field intensity. The primary current concentrates the magnetic field at the core, and the probe senses and outputs a PWM signal. This signal is then converted to a voltage signal by an integrator circuit. This voltage signal is then converted to a current by a circuit and passed through a compensation coil. The magnetic field generated by the compensation coil is equal in magnitude to the magnetic field generated by the primary current and in opposite directions, thus ensuring that the magnetic probe operates in a zero-flux state.

Fluxgate current sensors are characterized by high accuracy, excellent linearity, minimal temperature drift, fast response time, and excellent dynamic characteristics.
