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.

What Is The High Precision Current Sensor

High precision current sensors are core measuring components designed to capture tiny variations of electric current with extremely low measurement error, high stability and outstanding resolution. Unlike ordinary conventional current sensors that only meet basic detection demands, high-precision models target scenarios requiring rigorous current monitoring, accurate energy metering and closed-loop automatic control, and they have become indispensable hardware in new energy power systems, industrial automation, medical electronics, aerospace equipment and high-end laboratory testing.

Leakage Current Sensor: Indispensable Detector for Electrical System Safety

A leakage current sensor ​is a high-precision measuring component specially designed to track residual leakage current inside power circuits, acting as the first line of defence against electric shock and electrical fire hazards in modern power distribution, new energy and industrial control systems. Ordinary current transformers only measure load current, yet this sensor focuses on tiny stray currents escaping from damaged insulation, aging cables, faulty wiring or incomplete equipment grounding, which pose hidden safety risks hard to spot via regular monitoring tools. It converts faint leakage signals into readable electrical outputs to support real-time monitoring, threshold alarming and power interlock protection.

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.
