2. Current sensing - Wikipedia

   en.wikipedia.org/wiki/Current_sensing

   Fluxgate sensors or Saturable inductor current sensors work on the same measurement principle as Hall-effect-based current sensors: the magnetic field created by the primary current to be measured is detected by a specific sensing element. The design of the saturable inductor current sensor is similar to that of a closed-loop Hall-effect ...

3. Eddy-current sensor - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_sensor

   Eddy-current sensor. Eddy current sensor s uses the principle of eddy current formation to sense displacement. These sensors measure shaft displacement in rotating machinery and have been around for many years as they offer manufacturers high-linearity, high-speed measurements, and high resolution. [1] Eddy currents are formed when a moving or ...

4. Fiber-optic current sensor - Wikipedia

   en.wikipedia.org/wiki/Fiber-optic_current_sensor

   A fiber-optic current sensor (FOCS) is a device designed to measure direct current. Utilizing a single-ended optical fiber wrapped around the current conductor, [1] FOCS exploits the magneto-optic effect (Faraday effect). [2] The FOCS can measure uni- or bi-directional DC currents up to 600 kA, with an accuracy within ±0.1% of the measured value.

5. Hall effect sensor - Wikipedia

   en.wikipedia.org/wiki/Hall_effect_sensor

   A Hall effect sensor (also known as a Hall sensor or Hall probe) is any sensor incorporating one or more Hall elements, each of which produces a voltage proportional to one axial component of the magnetic field vector B using the Hall effect (named for physicist Edwin Hall). Hall sensors are used for proximity sensing, positioning, speed ...

6. Rogowski coil - Wikipedia

   en.wikipedia.org/wiki/Rogowski_coil

   Rogowski coil. A Rogowski coil is a toroid of wire used to measure an alternating current I(t) through a cable encircled by the toroid. The picture shows a Rogowski coil encircling a current-carrying cable. The output of the coil, v(t), is connected to a lossy integrator circuit to obtain a voltage Vout(t) that is proportional to I(t).

7. Eddy-current testing - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_testing

   Eddy current testing (ECT) as a technique for testing finds its roots in electromagnetism. Eddy currents were first observed by François Arago in 1824, but French physicist Léon Foucault is credited with discovering them in 1855. ECT began largely as a result of the English scientist Michael Faraday 's discovery of electromagnetic induction ...

   Current Sensor Market is Expected to Expand at an Impressive 10.30% CAGR through 2031 | SkyQuest Technology Westford, USA, Nov. 18, 2024 (GLOBE NEWSWIRE) -- SkyQuest projects that the Current Sensor Market will attain a value of USD 5.79 billion by 2031, with a CAGR of 10.30% over the forecast period (2024-2031).

9. Inductive sensor - Wikipedia

   en.wikipedia.org/wiki/Inductive_sensor

   An inductive proximity sensor is a non-contact electronic proximity sensor. It is used for positioning and detection of metal objects. The sensing range of an inductive switch is dependent on the type of metal being detected. Ferrous metals, such as iron and steel, allow for a longer sensing range, while nonferrous metals, such as aluminum and ...
