The Hall Effect, discovered by Edwin Hall in 1879, describes the phenomenon where a magnetic field applied perpendicular to the flow of electric current induces an electric potential difference perpendicular to both the current and the magnetic field. This principle forms the foundation of Hall Effect linear current sensors.

Principle of Hall Effect Linear Current Sensors:

Hall Effect linear current sensors consist of a semiconductor material with a thin conducting layer. When a current flows through this conductor placed in a magnetic field, the Lorentz force exerted by the magnetic field on the charge carriers causes a charge separation, resulting in an electric potential difference known as the Hall voltage. This voltage is directly proportional to the magnitude of the magnetic field and the current passing through the conductor. By measuring this Hall voltage, the current can be accurately determined.

Mechanism of Hall Effect Linear Current Sensors:

Hall Effect linear current sensors employ a Hall element, which is a small piece of semiconductor material mounted on a substrate. The substrate serves as mechanical support and also ensures proper heat dissipation. The Hall element is carefully designed with a precise Hall voltage sensitivity known as Hall coefficient, which determines the current-to-voltage conversion.

When current passes through the conducting layer of the Hall element, the Lorentz force causes charge carriers to accumulate on one side of the element, creating a potential difference. By applying a reference voltage, it is possible to measure the potential difference between the two sides of the Hall element accurately. This potential difference directly corresponds to the current passing through the sensor, providing a precise measurement.
