    ibg's eddyvisor® C is the new standard for eddy current testers for crack, pore and grinder burn detection in production and laboratory settings. The eddyvisor® C is designed to identify flaws in components, mass-produced parts and semi-finished products using Preventive Multi-Filter Technology (PMFT). 

    Compact Design

    The eddyvisor® C features a high-powered, compact modular design with a maximum of 16 independent crack detection channels, a maximum of 32 structure test channels and their respective combinations. Its touchscreen interface is intuitive and easy-to-use and functions and test results are prominently displayed. The measuring signal is digitally processed with unique processors immediately after the pre-amplifier providing the most stable test results possible.

    Compatible Across All ibg Probes and Coils

    The eddyvisor® C is compatible with all coils and probes from the ibg family of instruments. The eddyliner® C is recommended for new testing implementations as well as for upgrading existing installations with the latest eddy current technology.

    Advanced Crack and Grinder Burn Detection

    ibg's Preventive Multi-Filter Technology (PMFT) simplifies the inspection process for crack and grinder burn detection, eliminating the need for experts to perform sophisticated and time consuming manual processes. PMFT automatically creates tolerance zones by simply scanning good parts. This process is a monumental shift in how crack and grinder burn flaw detection is performed and is unique to ibg worldwide.

    While calibrating with PMFT, good parts surface areas are scanned, and the eddy current variations are recorded simultaneously in each of 30 band pass filters. 360-degree tolerance zones are auto-generated within each filter band, capturing the allowable "noise" from good parts including such characteristics as edge effects, hardness profile run out, eccentricity, etc. This process greatly reduces pseudo rejects while retaining visibility to actual flawed parts.

    Ready to Test in Minutes

    You can calibrate the eddyvisor® C with ibg's unique "good-part-only-concept" that enables you to set up in minutes. As soon as you test a sample of good parts and they are recorded as reference parts, you can begin testing. Tolerance zones within each of the 30 PMFT filter bands are auto-generated allowing good part fingerprints in each of the 30 PMFT filter bands. After recording material data, with one key press, you can switch to Preventive Multi-Filter Test and begin testing. There is no faster, more reliable eddy current testing process currently available.


    Ergonomic Design

    All functions and test results including for complex systems are clearly displayed and can be viewed at a glance, enabling correct and smooth operation, even for inexperienced operators.

    Stations and Locations

    The eddyvisor offers a unique station and location concept as a solution for 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 to get a valid station result. Stations are independent of other stations. Different stations can take different operating conditions. For example, one station can be testing parts, and another station can be recording new calibration data or be 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 optimized for that area without disturbing testing of the other areas.

    View of Test Part

    At stations with at least two and a maximum of 22 locations, a picture of the test part created by the customer may be included. The coloration of the test part picture shows a visual representation of the test result for the single location of the station. A huge help for the operator especially in a test system with a 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 backtracing individual parts.

    History of Reference Parts

    The histogram displays the test results of all reference parts at a glance. After recording reference parts and crosschecking in the laboratory if a part is determined not to be 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 can 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 a 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 resets the counter, and 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 authorization concept that operates by key switch.

    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.
