Principle
The open-loop current sensor uses Ampere’s law (the magnetic field generated around an energized straight wire is proportional to the current in the wire), and the characteristics of the hall device to detect the magnitude of the magnetic field strength B generated by the primary current to detect the current in the wire. Within the linear range of the hysteresis cycle, the proportional relationship between B
and I is:
