eddyvisor®S Eddy Current Tester Description.

The eddyvisor® distinguishes itself with its high performance modular concept with max. 16 independently working crack detection channels and max. 32 structure test channels all in a very compact design. Additionally, it offers unique features for the realization of sophisticated test tasks using the eddy current technique, combined with the well known ibg test reliability and ease of operation.

The ergonomic interface enables easy and simple operation via touch screen. All functions and test results are captured at a glance. Digital processing of the measuring signal with unique processors, immediately after the pre-amplifier guarantees the greatest possible stability of test results.

The eddyvisor® eddy current tester is based on the long proven ibg system concept. All coils, probes, rotating heads and other system components are standardized worldwide. So eddyvisor® is the solution for new tasks and to upgrade existing production machines to equip them with state of the art eddy current technology.

  • General
  • Technical Data


  • Ergonomic design
    All functions and test results including for complex systems are clearly arranged to be viewed at a glance. This enables correct and easy operation even for inexperienced operators.
  • Stations and Locations
    The eddyvisor® offers a unique station and location concept for solution of complex applications. Maximum eight stations can be defined which may include up to 32 locations. All test locations of one station belong to the same part and are summed up in a station result. This result can be taken for sorting. The part must be tested at all locations of that station in order to get a valid station result. Stations are independent from other stations. Different stations can take different operating conditions. For exapmle, one station can be testing parts, and another station can be recording new calibration data or being adjusted. In addition, each location has its own set of reference data and tolerance zones. For crack detection, for instance, it is possible to define different areas of a test part (faces, radii, undercuts etc.) and to test each of them with different settings switchable via PLC on the fly. So each area of a test part, including areas with high basic noise (e.g. radii) or with very low basic noise (e.g. high precision machined or super finished surfaces) can be tested with the setting optimised for that area without disturbing testing of the other areas.
  • View of test part
    At stations with at least two and maximum 22 locations a picture of the test part created by customer may be included. The test result of the single locations of the station is visualised by coloration of the test part picture. A huge help for the operator especially in test system with complex setup. These test part pictures can be displayed in the survey of all stations as well (however, w/o coloration of result).
  • Part types
    Maximum 100 part types (at more than eight locations max. 50) in crack detection and max. 250 part types in structure test with all settings and reference data can be stored in the device memory and switched over manually or via PLC for automated processes.
  • Part ID
    Test data for individual parts can be allocated to the part. The eddyvisor® can be informed before the test of an alphanumeric serial number from a PLC or another system (QR-code reader or similar). This identity is connected with the related test data, stored in the eddyvisor® and additionally written via the eddyLogger Software or as Q-DAS compliant set of data. Indispensable for back tracing individual parts.
  • History of reference parts
    The histogram displays the test results of all reference parts at a glance. When after recording of reference parts and afterwards crosschecking in the laboratory it is determined that a part is still not good, it can be removed from the reference parts with one keystroke.
  • History of sorting parts
    The multi-colored histogram displays the test results of up to 1000 sorted parts and additionally the last 100 bad parts, so they can be observed at a glance and evaluated later. Test results of questionable rejected parts can be recorded as tentative reference parts and later destructively cross checked in the laboratory. If such questionable rejected parts are later found to be good, they can be added to the reference parts with one keystroke. Pseudo rejects can be diminished.
  • AQDEF quality data export Q-DAS standard compliant (option)
    Test data are transferred after termination of each test part via Ethernet to a protocol computer where the free eddyLogger Q-DAS software receives the data and provides them AQDEF compliantly to the QSSTAT interface. The software allows the user an individual configuration. The following options are available per test station: selection of data to be stored; storage with K-field or abbreviated separator spelling; memory format as DFD/DFX or DFQ files; free choice of amount of test parts to be stored per file. The eddyLogger software may record and administrate parallel the test data of several ibg instruments within one Ethernet network so that one acquisition computer is able to supervise several eddyvisor® and/or eddyliner® instruments.
  • Data storage in general
    Test results, part types and instrument settings are stored internally on a tough flash-memory and externally via USB stick. Test results may be additionally logged via network. A ring buffer logfile records all internal failures and allows fast debugging for service.
  • Automation without PLC
    Direct control of sorting devices, paint marking systems or indicating lamps is possible with the integrated 24 V DC (2.5 A) power supply, together with the autostart function providing a low cost solution for small automated systems without an additional PLC.
  • Counter preset
    The function “box counter” monitors the filling height of containers to avoid overfilling. Testing is paused automatically as soon as a preset value of tested parts is reached. The operator changes the containers and reset the counter, testing starts again automatically.
  • Remote control
    The eddyvisor® is remote controlled by each network PC via VNC viewer software.
  • Access protection
    The instrument offers a multi-level access authorisation concept that operates by keyswitch.
  • Help function
    The user always has access to a context sensitive help function on the device screen which often renders a look into the manual unnecessary.
  • Languages
    Included are: German, English, Spanish, French, Italian, Czech, Polish, Portuguese, Chinese, Hungarian, Japanese, Korean and Russian. Other languages as option.
  • Screen
    Tough 15” TFT touch screen, color display, resolution 1024 x 768 pixel, operable with gloves
