Hall Effect Current Sensors

First discovered by physicist Edwin Hall in 1879, Hall effect current sensors have become the dominant isolated current measurement component across power electronics, automotive and industrial equipment, solving critical limitations of traditional shunt resistors and current transformers. Based on the Hall effect principle, when charged carriers inside a semiconductor plate pass through a perpendicular magnetic field, a measurable transverse voltage (Hall voltage) forms. Since the magnetic flux surrounding a conductor is linearly proportional to its carried current per Ampere’s law, the Hall voltage can be converted into an accurate signal representing current magnitude, achieving fully galvanic isolation between high-voltage primary circuits and low-voltage control circuits.

Hall Current Sensor VS Eddy Current Sensor

​Current sensing technologies play a critical role in modern industrial automation, power monitoring, renewable energy systems, electric vehicles, and electronic equipment. Among the many available technologies, eddy current sensors and Hall current sensors are widely used for non-contact measurement applications. Although both technologies can detect electrical or magnetic changes without direct electrical contact, they operate based on different principles and are designed for different measurement tasks.

What Is A Hall Current Sensor?

The core principle involves a Hall element, a semiconductor component that generates a small voltage when exposed to a magnetic field. When current flows through a conductor, it creates a circular magnetic field around the wire. The sensor positions this Hall element near the conductor to detect this magnetic field. The strength of the magnetic field is directly proportional to the magnitude of the current passing through the conductor. As the current changes, the magnetic flux density varies, causing the output voltage of the Hall sensor to change accordingly.

What Is An Alternating Current Sensor?

An alternating current sensor, often referred to as an AC current sensor, is an electronic device designed to detect, measure, and convert alternating current flowing through a conductor into a usable electrical signal, such as voltage or a digital output, for monitoring, control, or protection purposes. Unlike direct current (DC), alternating current continuously changes direction and magnitude in a periodic cycle, typically at 50 or 60 hertz in mains power systems, requiring specialized sensing mechanisms distinct from DC measurement tools.
