A Hall effect current sensor is a device that measures current using the Hall effect in a magnetoelectric conversion element, known as the Hall element. These sensors are capable of non-contact detection and continuous measurement of AC and DC currents, with some models capable of detecting currents up to 4000A.
Hall effect current sensors are utilized in various applications:
Hall effect current sensors operate by converting a magnetic field around a current into voltage (Hall voltage) using a semiconductor Hall element. The sensor measures this voltage to determine the current value. The Hall effect occurs when a magnetic field perpendicular to current flow induces an electromotive force in an orthogonal direction.
The sensor measures current without contact, providing excellent insulation properties and the ability to measure various types of currents.
These sensors vary in terms of current detection range, form factors, and mechanisms. They are available in through-hole and clamp types and can use Hall ICs or feedback current for magnetic field cancellation. The choice of sensor depends on the specific application requirements.
