Programmable Hall Effect Current Sensors

Programmable Current Sensors

Current sensors, also known as current transducers, measure the current flowing through a conductor by monitoring the magnetic flux associated with the conductor. They can measure AC or DC current while providing galvanic isolation between the high-current source and sensor output.

The preferred method is to use a Hall Effect device, a small circuit designed to detect a magnetic field, translate the field strength, and then output a voltage proportional to the current. Two basic types of current sensors incorporate Hall devices: An open or closed-loop system. The advantages of an open loop type are low cost and ease of application.

ICE offers both busbar mount and PCB mount options in current sensors. Both utilize a unique hall effect device that operates parallel to the current flow and are programmable. The advantages to the end user are small packages for the current measured significantly helping reduce overall design size. The ability to program the measurable range maximizes the voltage output resolution. As detailed in ICE’s updated Application Note (ISB-AN1-R1), these design choices enhance accuracy, bandwidth, and flexibility, ensuring reliable performance across demanding applications.
