Hall Effect Open Loop Current Sensor is a current measurement device which develop on base of the hall effect principle, it can accurately measure DC, AC, pulsed current in isolation way.


Principle: Hall Effect Open Loop Current Sensor develops on base of open loop operation principle. Primary Current IP produce a magnetic field thanks to the air gap of magnetic core, open loop current sensor amplify the Hall generator voltage to provide an output voltage, this also known as direct measurement.


Features: Low insertion loss, Space saving, High accuracy, Low-cost sensing product, Fast response time


Applications: Widely used in servo drive, variable frequency drive, DC Panel, Motor Control, HVAC, over current protection and current monitoring of electronic circuits.
