Featuring DC to 5-MHz bandwidth, Allegro MicroSystems' galvanically isolated, high-accuracy magnetic current-sensor IC with zero current reference (ACS37030), and overcurrent fault with internal pull ...
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 ...
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 ...
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 ...
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, ...
Eddy current displacement sensors (ECDS) represent a mature, yet continuously evolving, non-contact measurement technology that utilises the principles of electromagnetic induction. When an ...
