Balance principle and operation process of Closed loop Hall Effect Sensor

- Feb 16, 2019-

The Closed loop Hall Effect Sensor generally adopts two main principles in the process of operation. The first is the principle of magnetic balance, and the second is the principle of Hall effect.


Closed loop Hall Effect Sensors mainly use the principle of magnetic balance. Therefore, some materials are called zero-flux current sensors. As for the Hall effect, it means that the energized conductor, under the action of the external magnetic field perpendicular thereto, can generate magnetic induction intensity with the applied magnetic field and current flowing through the conductor in a direction perpendicular to the direction of the current and the direction of the magnetic field. Proportional induction potential.


In the process of working, the Closed loop Hall Effect Sensor has zero magnetic induction in the actual core. Therefore, the "proportional" characteristic of the Hall effect itself is no longer important here.

Knowing the principle, how to call it is no longer so important!
