Named after the scientist who discovered the principle in 1879 (Edwin Hall, 1855 - 1938), the Hall effect is a fascinating use of electromagnetic powers that has been harnessed to a myriad of technical uses. In the century and a half since it was discovered by an enterprising graduate student at Johns Hopkins University, many inventors have found ways to use Hall effect sensors to detect and measure vital information over a wide range of applications, from automobile motors to rocket technology, from computers to music and sound equipment and much, much more.
The Hall effect works on principles of electrical currents as they pass through a solid object, and the effect that a magnetic field will have on the current. The electric current passes from one end of the solid object to the other and causes particles in the object to move through it in a basically straight line, until a magnetic field is applied perpendicular to the flow of electric current. When this happens, the particles veer to the side with the magnetic charge, so that more charged electrons gather on one side of the object than the other.
Using known constants as to how these reactions will occur with different levels of magnetic field and electrical current, Hall effect sensors are able to measure changes in the input to the device. Used for applications as diverse as speed detection, current sensing, proximity switching and positioning sensing, every industry has needs for sensitive equipment able to deliver crucial information, and sensors are available in a vast range of housings, fittings and sizes for all uses.
When looking for these sensors, Sensor Solutions is the first to know what needs you have in sensing equipment. You are then able to figure out what will serve your needs out of the diverse range of types produced. The options available in Hall effect sensors can fit almost any industrial need for detection and measurement devices, and deliver the most accurate and useful measurement and detection data available.
