  2. Hall effect sensor - Wikipedia

    en.wikipedia.org/wiki/Hall_effect_sensor

    Hall effect devices produce a very low signal level and thus require amplification. The vacuum tube amplifier technology available in the first half of the 20th century was too large, expensive, and power-consuming for everyday Hall effect sensor applications, which were limited to laboratory instruments.

  3. Hall effect - Wikipedia

    en.wikipedia.org/wiki/Hall_effect

    The term ordinary Hall effect can be used to distinguish the effect described in the introduction from a related effect which occurs across a void or hole in a semiconductor or metal plate when current is injected via contacts that lie on the boundary or edge of the void. The charge then flows outside the void, within the metal or semiconductor ...

    The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect current sensor; the only difference is that this method uses the saturable inductor instead of the Hall-effect sensor in the air gap. Saturable inductor current sensor is based on the detection of an inductance change. The saturable inductor is ...

    en.wikipedia.org/wiki/Spin_Hall_effect

    Schematic of the spin Hall effect Schematic of the inverse spin Hall effect. The spin Hall effect (SHE) is a transport phenomenon predicted by Russian physicists Mikhail I. Dyakonov and Vladimir I. Perel in 1971.

  7. Variable reluctance sensor - Wikipedia

    en.wikipedia.org/wiki/Variable_reluctance_sensor

    Hall effect sensors are true zero-rpm sensors and actively supply information even when there's no transmission motion at all. One area in which VR sensors excel, however, is in high-temperature applications. Because operating temperature is limited by the characteristics of the materials used in the device, with appropriate construction VR ...

    en.wikipedia.org/wiki/Circuit_diagram

    A circuit diagram (or: wiring diagram, electrical diagram, elementary diagram, electronic schematic) is a graphical representation of an electrical circuit. A pictorial circuit diagram uses simple images of components, while a schematic diagram shows the components and interconnections of the circuit using standardized symbolic representations ...
