Eddy Current Dynamometers (Dynos) Providing Precise Control and Low Maintenance. Our eddy current dynos are simple, cost effective, torque measuring devices for a large range of test purposes. They are available in standard and high speed models with many speed and torque versions.
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. The moving fluid creates a space devoid of downstreamflowing fluid on the downstream side of the object. Fluid behind the obstacle flows into the void creating a .
Eddy Current Testing (ECT) is a well established technology for the inspection of metallic components for surface breaking flaws. It is used for component testing in the aviation and automotive industry.
Eddy current technique is an important electromagnetic nondestructive evaluation technique that is widely used in power, aerospace, petrochemical and other industries for detection of surface cracks and subsurface damage in components made of metallic materials.
Eddy Current Testing (ET) is a nondestructive test technique based on inducing electrical currents in the material being inspected and observing the interaction between those currents and the material. Eddy currents are generated by electromagnetic coils in the test probe, and monitored simultaneously by measuring probe electrical impedance. The Eddy Current Testing Process occurs as follows: When a .
Eddy currents are often generated in transformers, leading to power losses. To combat this, thin laminated strips of metal are used in the construction of power transformers, rather than making the transformer out of one solid piece of metal. The thin strips are separated by insulating glue, which confines the eddy currents to the strips.
Eddy current brakes come in two geometries: In a linear eddy current brake, the conductive piece is a straight rail or track that the magnet moves along. In a circular, disk or rotary eddy current brake, the conductor is a flat disk rotor that turns between the poles of the magnet.
Olympus eddy current probes consist of the acquired brands of Nortec and NDT Engineering. We offer more than 10,000 standard and custom designed eddy current probes, standard references, and accessories. This section features many of the standard design probes that are available in a wide range of diameters, frequencies, and connector styles.
Zetec Eddy Current technology and products provide a fast efficient solution for near surface anomalies in conductive material. A magnetic field from a coil is induced into conductive material where anomalies in the material create changes to the "eddy currents" that .
The eddy current method is well established for 100% zero defect crack and grinder burn detection on cylindrical parts. Systems utilizing rotating scanners can test cylindrical parts like rollers, bars and rods at very high test rates increasing productivity tremendously.
Developing Eddy Current inspections for wheel bearing studs to sort poorly heat treated parts that a major fastener inspection company was unable to do 250,000 saved. Designed Eddy Current instrument capable of dual applications such as material testing and crack detection, eliminating the need to maintain spare instruments
Eddy current. Eddy current loss takes place when a coil is wrapped around a core and alternating ac supply is applied to it. As the supply to the coil is alternating, the flux produced in the coil is also alternating. By Faraday's law of electromagnetic induction, the change in flux through the core causes emf induction inside the core.
Eriez' RevXE® Eddy Current Separators feature an eccentrically mounted magnetic rotor within a nonconductive shell for the separation of nonferrous metals. The rare earth rotor produces a powerful focused field at the end of the belt.
A: Quick Answer. An eddy current is an electrical current induced in a piece of metal due to the relative motion of a nearby magnet. Any time a magnet passes a metallic object, its magnetic field induces an electric current, which swirls around near the surface of the metal like an eddy in a river.
EDDY CURRENTS. After reading this section you will be able to do the following:. Explain what an Eddy Current is. Discuss the one requirement necessary for a current to be induced into an object.

Criterion NDT's CR11 single channel eddy current test instrument is specifically designed to find material defects such as cracks and flaws in components during production processes – in realtime. This helps you to quickly detect and separate flawed product, reducing scrap and warranty costs.
The eddy current induces because of the interaction of the variable magnetic field and conductor. The loss which occurs because of the reversal of the magnetising force is known as the hysteresis loss. The eddy current loss occurs because of the interaction of magnetic field and conductor. The hysteresis loss occurs because of the reversal of the magnetism. The eddy current loss is minimised by using the thin .
