Sensors are energy conversion devices. Sensors or transducers convert the physical world of light, pressure, temperature, flow, level, acceleration, force, etc. to electrical signals but generally ...

Tick tracer. Glow meter. Sniffer. They go by many names, but capacitive voltage sensors are all designed to do one thing: detect the presence of voltage in a wire or piece of equipment without ...

This article is a technical document of Allegro’s Hall effect sensor integrated circuits, how these devices were built, and how Allegro use the Hall effect principle to develop these devices. It ...

You’ve probably seen probes that detect live wires in, for example, home wiring, without having to actually probe the wire. These are sometimes used to test strings of Christmas lights, too. We’ve ...

Electric motors that are either poorly maintained or which lack the proper electrical protection are the second greatest cause of electrical fires. So says the Factory Mutual Research Corp., a ...

Designed specifically for high-voltage sensing, a new generation of optically isolated amplifiers make monitoring and system protection circuits more accurate and easier to design. These iso-amps can ...

There are many cases where a power supply needs an internal current-limiter function, usually built using a current sensor, a control circuit, and a pass transistor. The current sensor itself can be a ...

If a charged particle beam interacts with structures of different electric conductivity in a microelectronic circuit, this leads to local changes in the electric potential at its surface. In a ...

A branch circuit consists of the conductors between the final overcurrent protection device (OCPD) and the point of use outlets [Art. 100] (Fig. 1). Article 210 ...
