The advantages of eddy current testing are: Sensitivity to surface defects Able to detect defects of 0 5mm in length under favourable conditions Can detect through several layers The ability to detect defects in multi-layer structures (up to about 14 layers) without interference from the planar interfaces Can detect through surface coatings
Inspection software for automatic eddy current signal analysis constantly works on powerful and highly sophisticated software for signal visualisation and for automatic analysis of eddy current (carbon steel duplex super duplex etc ) is a DELTA TEST development and is only offered by us For this special software with artificial
Eddy Current Test Systems After launching our first generation of eddy current test instruments over 30 years ago customers approached us with a request - can we supply innovative turnkey eddy current test systems from one source The answer was Yes We have since developed many systems for custom applications all over the world
The eddy current array technique (ECA) is a derivative of conventional eddy current testing and shares the same electromagnetic/inductive principles of eddy current The word "array" means that in comparison to a single coil sensor many adjoining eddy current coils are forming a coherent eddy current assembly
Our wide range of standard eddy current accessories includes encircling coils rectangular coils inner diameter coils flat coils and probes Customized products for special test tasks are provided by our in-house design and manufacturing departments ibg eddy current coils stand out due to highest test sensitivity and temperature stability
Eddy current loss P e = K e B max 2 f 2 t 2 V watts Where K e = constant B max = maximum flux density in Tesla f = frequency of magnetic reversal in Hz t = thickness of laminations in mm V = volume of core in m 3 This eddy current loss formula or equation can be used in all electrical machines like transformers AC and DC motors to calculate
Eddy current (ECT) Weld Probes allow welds to be efficiently inspected for near-surface cracks because the weld can be inspected through paint or metallic coatings To view the ETher NDE selection of EC Weld Probes click here To find out more about Special Design EC Weld Probes click here
2 2 3 2 Retrieving data stored in the component's subsurface region using high-frequency eddy current technology The data described in this section which were introduced by locally heat treating the component's subsurface region are visually inconspicuous and can therefore only be securely detected by means of a retrieval technology which is not based on an optical method
Eddy current testing uses the principle of electromagnetic induction to detect flaws in conductive materials An excitation coil carrying current is placed in proximity to the component to be inspected The coil generates a changing magnetic field using an alternating current which interacts with the component generating eddy currents
EDDY CURRENT REAR The revolution for E-MTB's Our first real E-MTB specialist for All Mountain and Enduro It allows uncompromising riding even uphill takes fierce acceleration as well as technical riding on the trails Its solid appearance comes from the stable blocks more rubber and the big widths
Our eddy current testing equipment and solutions will meet the critical requirements of your unique application and deliver productivity quality and safety Measures or detects surface and subsurface cracks and seams alloy content heat treatment variations wall and coating thickness crack depth conductivity and permeability
Eddy Current Loss An electric current passed through a conductor creates a magnetic field this field varies in proportion to the current if alternating If the ac current carrying conductor is wound around an electrically conductive core – for example in a transformer – the varying magnetic field will according to Faraday's laws of induction induce currents in the core
HOW THE EDDY CURRENT SEPARATOR WORKS The Eddy current separator (ECS) is a conveyor tape made with a particular magnetic field in the head which is generated by high frequency polar wheel: when the non-ferrous metals are coming near to the magnetic field they are lifted and expulsed to one appropriate collecting canal while the inert materials freely fall down to another container
Eddy-current losses in cylindrical conductors with special applications to the alternating current resistances of short coils S Butterworth Google Scholar It is therefore important to have reliable formul for the eddy-current resistance of such coils in order to determine the conditions which will reduce the eddy-current losses to a
