Closed Loop Hall Effect Current Sensor HCB

Closed Loop Hall Current Sensors are designed for high-accuracy current measurement in demanding power and industrial applications. By combining Hall-effect sensing with closed-loop compensation, these sensors deliver excellent linearity, fast response, and stable performance over a wide current range.

The Ferrtx HCB series Hall Current Sensors are developed as standalone products, optimized for precise current detection in modern power electronics and control systems.

What Is a Closed Loop Hall Current Sensor?

A closed loop hall current Sensor measures current by detecting the magnetic field generated by a conductor and actively compensating it through a feedback coil. This closed-loop structure significantly improves accuracy compared to open-loop designs.

As a professional Current Sensor, it offers:

• High measurement precision

• Low temperature drift

• Excellent bandwidth and response time

Closed-loop technology makes these sensors suitable for both AC and DC current measurement.

Key Advantages of Closed Loop Current Sensors

Compared with traditional sensing solutions, Closed Loop Current Sensors provide several important benefits:

• High linearity across the full current range

• Fast dynamic response for transient signals

• Reduced offset and hysteresis

• Strong immunity to external magnetic interference

These characteristics make them a reliable Current Transducer for precision applications.

Hall Current Sensors for AC and DC Measurement

Hall Current Sensors based on closed-loop architecture can accurately measure:

• AC current
