RIPKA, P. Contactless measurement of electric current using magnetic sensors. Technisches Messen. 2019, 86(10), 586-598. ISSN 0171-8096. DOI 10.1515/teme-2019-0032.
We review recent advances in magnetic sensors for DC/AC current transducers, especially novel AMR sensors and integrated fluxgates, and we make critical comparison of their properties. Most contactless electric current transducers use magnetic cores to concentrate the flux generated by the measured current and to shield the sensor against external magnetic fields. In order to achieve this, the magnetic core should be massive. We present coreless current transducers which are lightweight, linear and free of hysteresis and remanence. We also show how to suppress their weak point: crosstalk from external currents and magnetic fields.
