Melexis has brought out a linear Hall-effect sensor that draws less than 5 µA at 100 Hz and integrates digital filters for enhanced performance.

• Hall-effect sensors used to control dc-electric motors can detect motor rotation direction, and rpm. • Improper inflation of aircraft tires drastically shortens tire life span, leading to premature ...

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 ...

Measuring a magnetic field can be very easy with some pretty low tech, or it can be very high tech. It just depends on what kind of measurement you need and how much effort you want to expend. The ...

As power electronics switching techniques advance, there is an increased need to accurately measure current for feedback control and system monitoring. There are several methods to achieve this, and ...
