EddyStation MWII - Windows-Based Eddy Current Flaw Detector
Windows-Based Eddy Current Flaw Detector
Developed based on our many years of experience, the EddyStation MWII is the flagship model in our range of multi-frequency eddy current flaw detectors for maintenance inspection. With the detector connected to a PC via a USB cable, our dedicated Windows-compatible software allows the operator to view waveforms, save and retrieve data, identify defects in real time, and perform various other tasks.
Main Features
- Three-independent-channel flaw detection capabilities and a dual-channel arithmetic circuit enable a wide variety of inspections
-
To meet various on-site needs, the EddyStation MWII offers three-channel flaw detection capabilities required for maintenance inspection and incorporates a dual-channel arithmetic circuit to remove unwanted signals. It can also be used as a three-independent-channel flaw detector.
A four-channel type is optionally available.
- High-speed sampling
- The EddyStation MWII can perform high-speed sampling up to 10 kHz (10,000 points per second) to plot up to four types of signal waveforms simultaneously, which makes the detector ideal for high-speed inspection.
Its dedicated software is compatible with Windows 7, 8, 8.1, and 10.
- Instant defect identification in real-time analysis
-
Once waveform data predetermined from artificial flaws is input, the EddyStation MWII can create wall thinning curves. Then, based on waveforms obtained during an inspection, the detector can analyze the types and depths of the defects and display the results in a chart.
Test signals can be output to a commercially available chart recorder in real time. Some chart recorders can be set to automatically start operating at the start of an inspection. (This applies only to chart recorder models we have checked for compatibility.)
- Works perfectly with a bobbin coil designed to inspect heat exchanger tubes
- When an inspection is conducted based on tube row numbers, the EddyStation MWII detects tube ends, and then automatically performs phase analysis and records waveforms.
By using an optional remote pendant, the operator can start and end an inspection and check tube row numbers externally.
- Acquired waveforms can be used in other applications
-
On a PC not connected to the detector, the dedicated software starts up in playback mode, allowing the operator to reanalyze waveforms acquired on-site, paste images into other applications, or perform other tasks in a flexible manner.
