Fluxgate current sensors have emerged as a robust technology for the measurement of both alternating and direct currents, harnessing the non-linear magnetic characteristics of ferromagnetic materials.

Melexis has announced a magnetism-based current sensor that needs no ferromagnetic core, for measuring currents through power PCBs and busbars (see diagram). MLX91235 is gradiometric, taking a ...

The best place to measure current consumption is in the main power feed. The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary ...
