FAQs

What is a current transducer and how does it work?

A current transducer is an electronic device that converts an electrical current signal into a standardized, proportional output signal, typically a low-voltage analog or digital signal. It works by sensing the magnetic field generated around a conductor carrying current. In open-loop types, a Hall-effect sensor measures this field directly. In more precise closed-loop types, a compensation winding generates an opposing field to maintain a zero-flux condition in the core, and the current needed for this compensation provides the output signal, ensuring high accuracy.
