Introduction of Electric Current Sensor

An electric current sensor is an essential electronic device used to detect, measure, and monitor the magnitude of electric current in electrical circuits. It converts current signals into measurable voltage or digital output signals for power monitoring, equipment protection, energy metering, and industrial automatic control. Current sensors are widely applied in power supplies, new energy vehicles, photovoltaic systems, inverters, and industrial electrical equipment.

How Does A Hall Current Sensor Work ？

A Hall current sensor relies on the Hall effect, a fundamental physical phenomenon discovered by Edwin Hall. When a current-carrying conductor sits inside a magnetic field perpendicular to the flow of electric charge, charge carriers inside the conductor experience a sideways force. This force pushes positive and negative charges toward opposite sides of the material, creating a measurable voltage difference called the Hall voltage. Modern Hall current sensors use this principle to detect electric current without direct electrical contact with the measured circuit.

How Does A Hall Effect Sensor Work?

A Hall Effect sensor is an electronic device that detects magnetic fields and converts them into an electrical signal. It is widely used in industrial automation, current measurement, automotive systems, robotics, and electronic equipment because it can provide accurate, reliable, and contactless sensing. Hall Effect sensors are especially important in current sensors, where they are used to measure AC and DC current without directly connecting to the conductor.

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.
