The device allows you to detect surface defects like cracks, visualizing the signal from the continuity interruptions on the display. The design of the flaw detector allows to determine with high reliability the exact location and depth of defects even on rough surfaces of flat and curved shape, including under a layer of corrosion or in the presence of a protective coating of the controlled area of the product with a thickness of up to 3 mm. The principle of operation of the VD-12NFP eddy current flaw detector: The principle of operation of the VD-12NFP eddy current flaw detector is based on the phenomenon of electromagnetic induction. An alternating magnetic field created in the primary coil of the converter by means of a sinusoidal voltage generator excites eddy currents in the controlled product. A parasitic magnetic field formed by eddy currents at the locations of defects affects the measuring unit (two signal coils connected in series) of the converter, creating an electromotive force in it. The amplitude and phase of the secondary signal carries information about the properties of the defect and the position of the transducer relative to the surface of the controlled product. The output signal from the measuring unit of the converter, after amplification and processing using a microprocessor, is displayed on the readout of the device, and is also stored in the memory block for subsequent transmission to a personal computer. In addition, information about the defects is displayed on a piezoelectric bell used as an audio indicator. Design, features and advantages of the VD-12NFP eddy current control device: The VD-12NFP eddy current flaw detector is a portable device capable of working both in a desktop and in a suspended position in a special bag-case. This ensures convenient operation of the device in a variety of conditions: in the laboratory, in the factory shop or during field tests. The flaw detector consists of an electronic unit with controls and display of test results, as well as three replaceable converters with wear-resistant corundum tips connected to the electronic unit using a connector. The choice of the desired converter depends on the magnetic properties of the material. For the control of parts with grooves, a converter with an inclined tip is offered. The device is powered by 4 AA batteries located in the battery compartment of the electronic unit. The advantages of the flaw detector include: - a screen for visualizing the signal during measurement; - light weight and compact dimensions that allow you to use the device in almost any conditions; - the ability to control the quality of products of various curvature and surface roughness even in the presence of a protective coating or a layer of corrosion; - wear resistance of converters, which is important when monitoring products with increased surface roughness (up to Rz£320); - automatic detection of the type of converter when connected, as well as the presence of built-in memory for storing control results; - the possibility to transfer data to a personal computer for storing or printing control protocols. Scope of application: Portability, high productivity, the ability to work with curved and rough surfaces, as well as the fact that the operation of the flaw detector is practically unaffected by humidity, pressure and contamination of the gas environment or the surface of the controlled product with non-conductive substances ensure the versatility of the device for detecting cracks in various materials. The eddy current flaw detector VD-12NFP is actively used in heavy industry for diagnostics of metal structures, assemblies and mechanisms for various purposes in factory workshops or laboratories, including at enterprises of railway transport, automotive industry, mechanical engineering, pipelines and metal structures. The VD-12NFP flaw detector can be used with equal success in the field, factory workshops, depots, laboratories and workshops to monitor the current condition, as well as to assess the degree of wear, the possibility and duration of further operation of such products made of metals and alloys as over-spring beams, wagon wheels, auto coupler housings, side frames, wheel couples and others.

The principle of operation of the VD-20NF eddy current flaw detector The principle of operation of the VD-20NF flaw detector is based on the generation of eddy currents on the surface of the controlled part and subsequent analysis of the signal at the output of the converter, which correlates with the characteristics of the active secondary field. The device consists of two main blocks: electronic one and electromechanical one, in which an eddy current converter of transformer type is installed. The controlled products (bearing rollers) enter through the input tray into the electromechanical unit of the flaw detector, where they move sequentially and fall under the pressure rollers of the overhead converter holder. The clamping mechanism is adjusted to each size of the rollers, so as to ensure tight contact with the curved surface and fix the tip of the transducer at the required distance from it. The detection of defects occurs due to the imbalance of the converter when it is located above the surface of the controlled product, caused by the interaction of the primary electromagnetic field generated by the converter with the secondary electromagnetic field of eddy currents induced in the controlled product by the primary field. When cracks are detected, the electronic unit of the flaw detector gives sound and light warning signals, and also triggers the electromagnet of the sorter, which directs the controlled roller into the tray for defective products. In the absence of defects, the controlled roller is directed towards the output tray of the flaw detector. Design features and advantages The VD-20NF eddy current flaw detector is equipped with removable input and output trays, power-on switches and a drive for feeding controlled products to the converter, as well as handrails for convenient transportation of the unit. The mechanisms of the electromechanical unit are protected by a frame made of steel plates. The electronic unit of the flaw detector is portable and can be installed both on the top panel of the electromechanical unit and on the surface of the desktop. Controls and indications of defect detection are located on the front panel of the electronic unit. The delivery package also includes a power adapter for the electronic unit and a tuning sample. The advantages of the VD-20NF flaw detector include: high reliability (the service life of the flaw detector is more than 10 years); it is easy to set up and operate; it has several types of defect detection alarms; the high probability of detecting defective products (at least 99.9%); low number of false positives (less than 5%). Scope of application According to the current standards of safety and product quality control during repair work in locomotive depots and repair plants, bearing rollers that have passed visual inspection and are recognized as suitable for further operation according to the criteria of geometry and condition of the working surface are subject to mandatory additional control using eddy current flaw detection to detect fatigue cracks invisible during visual inspection on the rolling surface of the rollers. The VD-20NF eddy current flaw detector allows for quality control and automatic disassembly of bearing rollers of various shapes and sizes both in laboratory and factory conditions in full compliance with the requirements of the regulatory documents of Rosstandart and the methods of performing control measurements used in JSC "Russian Railways".
