奧林巴斯MultiScan MS5800渦流探傷儀

The MultiScan MS5800 is a multi-technology system offering these technologies:

• Eddy Current
• Magnetic Flux Leakage
• Remote Field
• IRIS Ultrasound

MS 5800E
Tube Inspection with Eddy Current Testing (ECT)

• Condensers
• Feedwater heaters
• Heat exchangers
• Air conditioners

Eddy current testing is a noncontact method used to inspect nonferromagnetic tubing. This technique is suitable for detecting and sizing metal discontinuities such as corrosion, erosion, wear, pitting, baffle cuts, wall loss, and cracks in nonferrous materials.

• Two coils are excited with an electrical current, producing a magnetic field around them. The magnetic fields penetrate the tube material and generate opposing alternating currents in the material. These currents are called eddy currents.
• Any defects that change the eddy current flow also change the impedance of the coils in the probe.
• These changes in the impedance of the coils are measured and used to detect defects in the tube.

MultiScan MS 5800E Key Features

• Four simultaneous frequencies per input.
  This feature allows for inspection speeds up to 2 m/s with four frequencies on absolute and differential channels, without signal distortion.
• Electronic probe balancing.
  No separate external reference probe is required for absolute channel operation.
• 4 ECT inputs and up to 64 multiplexed channels.
  The MultiScan™ MS 5800E can support a large number of ECT channels to perform array probe inspections. Compared to single-channel inspection, the array probe technology allows for faster and easier surface coverage.

MS 5800U
Tube Inspection with an Internal Rotating Inspection System (IRIS) for Ferrous and Nonferrous Materials

• Boilers
• Feedwater heaters
• Air coolers
• Heat exchangers

The ultrasonic IRIS option is used to inspect a wide range of materials, including ferrous, nonferrous, and nonmetallic tubing. This technique detects and sizes wall loss resulting from corrosion, erosion, wear, pitting, cracking, and baffle cuts. Olympus digital IRIS inspection technology is used extensively as a prove-up technique for remote field testing, magnetic flux leakage, and eddy current inspections.

MultiScan MS 5800U (IRIS) Key Features

• Setup wizard
  Simplifies equipment calibration for different tube diameters and materials. The wizard also generates the reporting code for the inspection.
• Real-time gain and gate controls
  UT settings can be modified during the C-scan acquisition for quick optimization of signal detection.
• Real-time and continuous color C-scans
  Reduces missed flaws with C-scan displays. To enhance the quality and appearance of your reports, include color maps and cross-section views of defects.
• Full tube-length recording
  Used to analyze data off-line, and to assess results with customers.

MS 5800R
Tube Inspection with Remote Field Testing (RFT)

• Boilers
• Feedwater heaters
• Carbon steel heat exchangers

Remote field testing (RFT) is being used to successfully inspect ferromagnetic tubing such as carbon steel or ferritic stainless steel. This technology offers good sensitivity when detecting and measuring volumetric defect
