To sense high dc currents, designers typically use shunt resistors or Hall-Effect-based current sensors. But shunt resistors are plagued by Joule (I2R) losses and the need to open the circuit where ...

• 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 ...

The Allegro ACS713 provides economical and precise solutions for DC current sensing in industrial, commercial, and communications systems. The device package allows for easy implementation by the ...

Application characteristics help specifiers choose the best discrete sensor type. Industrial automation systems depend on sensors to detect what is going on with machinery and products for effective ...

Isolation in this case, is from the mains, and it transpires that finding something that will do the job safely is tricky. Three isolated Hall-based current sensing modules are easy to obtain, as far ...

As manufacturers seek to simultaneously reduce cost and increase rate for composite parts production, the ability to see inside molding processes in real time and monitor resin flow, viscosity, ...

Light sensors often use an infrared LED as a light source. Infrared LEDs have a greater intensity than LEDs that emit visible light. And when infrared photodiodes are used the sensors are relatively ...
