    EHY-88RFT Eight Channel Digital Eddy Current Flaw Detector
     
    Introduction:
    EHY-88RFT is suitable for on-line and off-line flaw detection of seamless pipes, welded pipes and other metal pipes, rods and wires, and can also be used for automatic flaw detection of mechanical parts. An absolute channel detects gradual defects and long-pass flaws; dual-frequency can use a high frequency to detect surface defects and a low frequency to detect internal depressions, ensuring better detection results. There is a far-field eddy current testing system, and it has the advanced performance of conventional multi-frequency, multi-channel array eddy current testing instruments. The instrument has the functions of welding seam detection and crack sounding.
    The EHY-88RFT instrument can use WindowsXP/Win7 platform notebook, and can be connected to the host through the computer USB high-speed communication port or network cable to achieve detection collection, high-speed data transmission and storage. It is especially suitable for flaw detection and wall thickness measurement of various pipelines such as copper, titanium, stainless steel, aluminum and zirconium in service and before service in electric power, petrochemical and other departments. Steel, cast iron) and non-ferromagnetic metal pipes (copper, aluminum, titanium, stainless steel, etc.) inner and outer wall defects, and can be analyzed and evaluated. It is not affected by probe lift-off, skin effect, uneven conductivity and magnetic permeability during detection. , which is an advantage that ordinary dual-frequency eddy current instruments do not have. During the inspection, it can effectively suppress the interference signal caused by the support plate, depression, probe shaking, sediment and cold working of the in-service pipe; the instrument can also be used for the center hole, blade, bolt hole and other mechanical parts of the steam turbine. Defect detection; it can also be used for pre-service and off-line flaw detection of boiler four pipes, oil pipes, water gas pipes, etc.
    Features:
    1. With automatic balance function, fast digital/analog electronic balance
    2. Equal amplitude, non-equal amplitude (phase or amplitude) and box alarm field setting
    3. Delayed hardware output alarm, real-time hardware output alarm
    4. It has the function of displaying the waveform of the fundamental frequency signal before the detection with the scale mark;
    5. A variety of display modes: voltage, impedance, time base and other display modes and single, double, four, and eight trace impedance plane diagrams, which fully reflect the phase, amplitude and other characteristics of the defect signal.
    6. Equipped with an automatic probe calibration system, with the function of displaying the waveform of the fundamental frequency signal before detection with a scale mark
    7. With delay marking, 0.00120.000 seconds
    8. Automatic or manual adjustment of eddy current signal amplitude and phase measurement, eddy current signal slow adjustment and extended playback;
    9. Internal and external clock selection
    10. It has the function of cutting end and end signal
    11. The cross-sectional view of the pipeline in service and the row and column numbers of the inspected pipes can be displayed on the screen at the same time;
    12. The cross-sectional view of the pipeline can be graded and marked, and finally the overview map of the pipeline in service can be formed;
    13. Can store a large number of testing programs and testing data
    14. Grading statistical test results (table and histogram display), easy for cumulative analysis and comparison;
    15. Eddy current signal playback extension function, measure the amplitude, phase and digital value of defects
    16. With phase/defect depth curve and amplitude/defect depth curve production and display function
    17. It has real-time multi-probe, multi-channel, and multi-combination detection functions; it can realize rapid scanning of multi-coil array probes, and simultaneously acquire the absolute and differential signals of each group of coils to realize flaw detection and thickness measurement at one time;
    18. With the function of crack depth measurement, digital display, easy to understand and intuitive
    Technical parameter:
