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 magnetic particle testing stand has a simple switch between circular and longitudinal magnetization modes, as well as easy movement and fixation of the solenoid and electrical contact for locating the test object in the working area of ​​the stand. Clamping of the controlled part during circular magnetization occurs in one movement. The stand can be installed on a stationary or mobile magnetic particle testing station. For ease of inspection after magnetization, a tray with a removable protective grid is provided. The protective rear wall protects against the spread of spray splashes outside the working area.

The principle of operation of the magnetization device: The device consists of two compact blocks made of non-magnetic material connected by a flexible magnetic circuit. In each block there is a permanent magnet made of neodymium-iron-boron alloy (Ne-Fe-B). When installing the blocks on the surface of the part, a closed magnetic circuit is formed with the direction of the magnetizing field from one pole to the other. Above the defect scattering fields, magnetic powder particles are deposited to form an indicator pattern. Design features and advantages of the device for magnetic particle control UN-5 The delivery package with the device includes a portable case, an inter-pole jumper installed during transportation, and a liner for fixing blocks with permanent magnets. The UN-5 portable device does not require electrical power and therefore can be used where the supply of stationary power is difficult or impossible under regulatory documents: in the field, when working at height, for inspection of capacitive equipment operating under pressure, etc. - The device is easy to use, lightweight and small-sized, working with it does not require special physical and technical training from the operator; - Flexible magnetic core allows you to use the device to control parts of complex shape; - The UN-5 magnetizing device is distinguished by an increased quality of the indicator pattern and an increased control zone due to a reduced uncontrolled zone near the poles and an improved ratio of the normal and tangential components of the magnetic field (Russian patent No. 60732); - The technical characteristics of the device comply with Russian and foreign regulatory documents, this being the reason of its widespread use in more than 40 countries, including Germany, France, Brazil and Norway. When monitoring, the controlled area is the central part of the area located between the magnetic poles of the device. The width of the monitored area is determined by the width of the magnetic poles of the device and is approximately 60 mm. The length of the monitored section depends on the inter-pole distance. the dimensions of the controlled area are given depending on the device's inter-pole distance: Inter-pole distance, mm 95: 75 55 Controlled area between the working poles, mm: 60x60 40x60 25x55 The length of the defect detection zone depends on the distance established between the working poles of the magnet on the controlled product. Defects are not detected in the areas adjacent to the poles of the magnet. The length of these sections is 18 mm with an interpolar distance of 95 and 75 mm. With an interpolar distance of 55 mm these sections are 13 mm long. Scope of application: Magnetizing devices for magnetic powder flaw detection are used in many industries, including railway, water and aviation transport, in the construction and operation of pipelines, in chemical and petrochemical production. The flexible link between the magnetic blocks allows the control of products of complex shape, for example, cylindrical tanks, high-pressure apparatuses, main pipelines, etc. When checking for defects, the device can be used together with other auxiliary equipment for: - preliminary and subsequent demagnetization; - application of a magnetic indicator (which can be dry or in the form of an emulsion); - magnetoluminescent control (with ultraviolet lamps).
