How a Zero Flux Current Transducer Works?

Danisense, the leader in high-accuracy current transducers for demanding applications, has produced a new tutorial video which discusses how – using the zero flux principle – current transducers can be produced with a measurement accuracy as accurate as 1ppm for applications such as power analysers in EV production, medical equipment such as MRI scanners and power supplies for particle accelerators.

The video explains zero flux technology, also called ‘fluxgate’ and how it works, including the use of a closed loop which balances opposing magnetic fields, so eliminating offset and linearity issues. Using this combination of techniques, it is possible to achieve extremely accurate results even in a harsh environment.
