Allegro’s ACS37200 200-A Hall current sensor slashes power dissipation with its 50-µΩ shunt, offering 1,400 V of isolation in ...

Sensing current, especially in higher-voltage settings, is often a challenge. It’s generally more difficult than voltage sensing, as it is usually “invasive” and requires “breaking” into the ...

Six automotive current sensors designed to enhance electric and hybrid vehicle performance, efficiency, and functional safety ...

Allegro’s two new magnetic current sensors enhance system efficiency and protection compared to discrete shunt-based current sensing circuits. The ACS37220 measures current up to 200 A, while the ...

Inductive eddy current position/displacement sensors require an electrically conductive target. The target does not have to be grounded, and in general, the more electrically conductive it is, the ...

Recently, I’ve been working on a solar off-grid monitoring system. In the system are a few split-core Hall effect sensors to monitor DC current in the solar panel current, the battery charge current, ...

The technique is called high-side current sensing. However, measurements at that location are fraught with problems. Of primary concern is that the measurement is at main line voltage, a problem if ...

Eddy current displacement sensors (ECDS) represent a mature, yet continuously evolving, non-contact measurement technology that utilises the principles of electromagnetic induction. When an ...
