2. Eddy-current testing - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_testing

   This is the basis of standard (pancake coil) ECT. NDT kits can be used in the eddy current testing process. [6] ECT has a very wide range of applications. Since ECT is electrical in nature, it is limited to conductive material. There are also physical limits to generating eddy currents and depth of penetration . [7]

3. Eddy (fluid dynamics) - Wikipedia

   en.wikipedia.org/wiki/Eddy_(fluid_dynamics)

   In fluid dynamics, an eddy is the swirling of a fluid and the reverse current created when the fluid is in a turbulent flow regime. [2] The moving fluid creates a space devoid of downstream-flowing fluid on the downstream side of the object.

4. Electromagnetic testing - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_testing

   If the test is set up properly, a defect inside the test object creates a measurable response. The term "electromagnetic testing" is often intended to mean simply eddy-current testing (ECT). However, with an expanding number of electromagnetic and magnetic test methods, "electromagnetic testing" is more often used to mean the whole class of ...

5. Remote field testing - Wikipedia

   en.wikipedia.org/wiki/Remote_field_testing

   Although RFT works in nonferromagnetic materials such as copper and brass, its sister technology eddy-current testing is preferred. The basic RFT probe consists of an exciter coil (also known as a transmit or send coil) which sends a signal to the detector (or receive coil). The exciter coil is pumped with an AC current and emits a magnetic field.

6. Dynamometer - Wikipedia

   en.wikipedia.org/wiki/Dynamometer

   An eddy current dyno system offers fast load response, which allows rapid tracking of speed and load, but does not allow motoring. Since most required transient tests contain a significant amount of motoring operation, a transient test cycle with an eddy-current dyno will generate different emissions test results.

7. Eddy-current sensor - Wikipedia

   en.wikipedia.org/wiki/Eddy-current_sensor

   Eddy current sensors are displacement sensors that use 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 ]

8. Alternating current field measurement - Wikipedia

   en.wikipedia.org/wiki/Alternating_Current_Field...

   Alternating current field measurement (ACFM) is an electromagnetic technique for non-destructive testing detection and sizing of surface breaking discontinuities. It was derived from the methods used in eddy-current testing and works on all metals, ferrous or non-ferrous. Since it doesn't require direct electrical contact with the surface it ...

9. Loop Current - Wikipedia

   en.wikipedia.org/wiki/Loop_Current

   A related feature is an area of warm water with an "eddy" or "Loop Current ring" that separates from the Loop Current, somewhat randomly every 3 to 17 months. [4] Swirling at 1.8 to 2 meters/second, these rings drift to the west at speeds of 2 to 5 kilometers/day and have a lifespan of up to a year before they bump into the coast of Texas or ...
