Magnetic particle flaw detector Teqtoflow-CG10

portable

Specifically designed to detect surface and subsurface defects in ferromagnetic materials, including incomplete fusion, cracks, and flocks. It plays a crucial role in assessing the structural integrity, strength, and mechanical properties of diverse workpieces, metal structures, and components of railway transport, both during manufacturing and operational phases. Operating on the principle of magnetization, it magnetizes the test object to uncover various discontinuities, followed by demagnetization for accurate analysis.Application:Building metal structuresGear wheelsCast partsCastingsForgingsOperational advantages:Smooth adjustment of current amplitudeOffers both constant and impulse current magnetizationProvides direct indication of magnetizing current amplitude valueFlexible adjustment of impulse current, including single pulse operation modeCustomizable magnetization and demagnetization time settingsAbility to save settings for efficient usageAutomatic overheating protection ensures safetyCompatible with various magnetizing devices for enhanced versatilityBenefits:Combines low weight with high output current value for optimal performanceAC/DC (rectified half-wave) operating mode allows both circular and longitudinal magnetizationDesigned in accordance with rigorous international standardsSuitable for operating in stationary magnetic particle test benchesOffers smooth adjustment of current amplitude, constant current magnetization, impulse current magnetization, magnetization time setting, and demagnetization for precise testingExploitation:The Teqtoflow-CG10 leverages magnetic particle inspection, a widely accepted non-destructive testing method. To conduct the inspection, a special magnetic powder must be applied to the surface under examination. During magnetization, the control zone exhibits the highest concentration of magnetic field lines directly above the defect. As a result, magnetized powder particles gather in this region, forming a distinct pattern. The density of these particles gradually decreases as they move away from the defect, such as cracks or discontinuities. Following magnetization, the indicator lines are visually interpreted to determine the localization, orientation, and extent of surface and subsurface defects. This resulting pattern can be compared with reference samples to further analyze the findings of the magnetic particle inspection.Technical specifications:CharacteristicValuesAlternative currentPeak AC, not less> 1000 АEffective AC, not less780 АRectified half-wave currentPeak value, not less> 1000 АEffective value, not less550 АFeaturesCurrent adjustmentSmoothCurrent indicationPeak value, 1 A resolutionCurrent measurement error, no more10 %Magnetization currentContinuous / intermittent (current-pause)Intermittent current parameters settingCurrent impulse duration0.02 – 9.98 s, with 0.02 s stepPause duration0.02 – 9.98 s, with 0.02 s stepMagnetization time controlManually (button on handle, foot switch, button on main device)DemagnetizationAmplitude-decreasing currentDemagnetization time setting50 periodsOperating characteristicsDuty cycle at max. power50 %Maximum duration of current supply10 sOpen circuit voltage3 VLength of high current cable3 mHigh current cable cross section95 mm²Power consumption2.5 kVAPower parameters230 V, 50 Hz, 10 APower cable (3 m length)Removable, waterproof connectorDimensions (width х height х depth)214 х 311 х 340 mmWeight without current cables16 kgDelivery set:Main unitCurrent cable (2.5 m length, 95 mm cross section) with pistol grip and melt-off electrodeCurrent cable (2.5 m length, 95 mm cross section) with pistol grip, melt-off electrode, and current switch on buttonPower cableOperating manualAdditional accessories:Magnetic coilCurrent cable and handlesMelt-off electrodes made of various metalsNon-standard length power cableCurrent ON/OFF foot switchCustom magnetizing devicesTrolleyFAQ (excerpt):What is Magnetic Particle Inspection (MPI)?Magnetic Particle Inspection (MPI) is a widely used nondestructive testing technique designed to detect surface and near-surface discontinuities in ferromagnetic materials like iron, nickel, cobalt, and their alloys. This method works by introducing a magnetic field into the object being tested. If there are any cracks or flaws, they disrupt the magnetic field, causing magnetic flux leakage. To visualize these imperfections, small ferrous particles (either dry powder or suspended in a liquid) are applied to the object's surface. These particles gather at the areas of flux leakage, forming visible indications that mark the location of the defects.Types of Electrical Currents Used in MPI:Alternating Current (AC): Best for detecting surface-level defects, AC creates a magnetic field that remains mostly on the surface of the object due to a phenomenon called the "skin effect." The current alternates polarity rapidly (50-60 cycles per second), meaning it does not penetrate deep into the material. This limits its use for subsurface detection but makes it ideal for identifying surface discontinuities.Full-Wave Direct Current (FWDC): FWDC is used when deeper penetration is required to find subsurface discontinuities. Unlike AC, FWDC can magnetize thicker cross-sections of material, making it more suitable for larger or thicker parts where surface inspection is insufficient.Half-Wave Direct Current (HWDC): HWDC provides a balance between surface and subsurface detection. Its pulsating current helps move the magnetic particles during inspection, increasing the likelihood of detecting surface cracks. This mobility of particles, combined with deeper penetration than AC, makes HWDC effective for both surface and shallow subsurface inspection.AC electromagnet is most effective for detecting surface-breaking indications, while some form of DC, such as FWDC or HWDC, is better suited for identifying subsurface defects. MPI is a versatile inspection method used in industries such as aerospace, automotive, and construction, where the integrity of metal components is critical.Characteristics / Technical specifications:Model: Teqtoflow-CG10Type: Portable magnetic particle flaw detectorInspection method: Magnetic Particle Inspection (MPI)Peak AC: > 1000 AEffective AC: 780 APeak rectified half-wave current: > 1000 AEffective rectified half-wave current: 550 ACurrent adjustment: SmoothCurrent indication: Peak value, 1 A resolutionCurrent measurement error: ≤ 10%Magnetization current: Continuous / intermittentCurrent impulse duration: 0.02 – 9.98 sPause duration: 0.02 – 9.98 sMagnetization time control: Manual (handle, foot switch, main device)Demagnetization: Amplitude-decreasing currentDemagnetization time: 50 periodsDuty cycle at max. power: 50%Max duration of current supply: 10 sOpen circuit voltage: 3 VHigh current cable length: 3 mHigh current cable cross section: 95 mm²Power consumption: 2.5 kVAPower parameters: 230 V, 50 Hz, 10 APower cable: Removable, waterproof connector, 3 mDimensions: 214 x 311 x 340 mmWeight (without current cables): 16 kg
