New current sensors have no magnetic circuits
https://www.electronics-lab.com/new-current-sensors-no-magnetic-circuits/
Clemens Valens @ elektormagazine.com discuss about LEM’s new current sensors which do not use the Hall effect make the measurement. Instead they integrate conductors for gradient measurement and provide immunity against the external fields. He writes: Here are some new integrated circuit transducers for AC and DC isolated current measurement up to 300 KHz that […]
