Anti-interference of current Hall sensor

- Feb 26, 2021-

The electromagnetic field A1 DC current transmitter closed-loop Hall effect current sensor uses the principle of electromagnetic field of the primary wire. Therefore, the following factors directly affect whether the sensor is interfered by external electromagnetic fields.

(1) Whether the size and frequency of the external current near the sensor changes;

(2) The distance between the external wire and the sensor, the shape and position of the external wire and the position of the Hall electrode in the sensor; A3 single-phase AC current transmitter

(3) Whether the material used to install the sensor is magnetic;

(4) Whether the current sensor used is shielded; in order to minimize the interference of the external electromagnetic field, it is best to install the sensor according to the installation guide.
