The eddy current test instrument eddyvisor® C is designed to detect surface-open and close to surface subsurface defects like cracks and pores on conductive test parts.
eddyvisor® C operates according to the fast and clean eddy current method and is specially designed for testing of components in a production environment. The instrument is capable of detecting surface cracks with a depth of only 0.05 mm on plane or rotation-symmetrical parts with surface speeds up to 50m/sec scan speed.
The path from calibration of eddyvisor® C to test mode is short and simple. lt is operated via a bright 15″ color touch screen with ergonomically designed user interface. Advanced electronics enable a hitherto unachievable level of function. The eddyvisor® C is available in different versions. The basic version has two crack test channels (resp. one crack test channel with lift-off compensation). Up to 16 channels may be provided.
One or several OK parts are required for calibration of the eddyvisor® C. In calibration mode, the crack detection probe is moved over the area to be tested on the OK part. Signals generated by the surface finish are taken over a large number of band pass filter settings and are displayed within individual tolerance fields for each band pass filter.
In test mode, all parts with signals exceeding the tolerance fields are sorted out as “NOK”. This guarantees detection of unexpected flaws as well as the specified flaws. The manual and time consuming setting to a complex defect is avoided. Setting is also possible by semi-skilled personnel. Traditional set up using a master crack can also be used.
Each crack test channel is independent. The test results of each channel are processed and displayed by the integrated PC. A variety of graphic display options of the test results are available, including bargraph, tolerance field, xy- x(t)- and y(t)-view or C-scan.
The test result per channel is “good” or “bad”. Historical test results can also be displayed as a histogram.
The crack test instrument eddyvisor® C has lift-off compensation. Special probes are needed. One lift-off probe requires two crack test channels. Lift-off compensation electronically balances changes of crack sensitivity which occur due to eccentricity or mechanical tolerances.
The eddyvisor® C can internally store up to 50 part types with the relating settings, which can be recalled manually or by PLC. All internally stored data may be transferred to a PC or stored on a USB-stick.
The eddyvisor® C is equipped with three USB 2.0 interfaces (two of them on front) as well as one Ethernet interface. A standard printer (USB) can be used for printing the test result.
An opto-isolated PLC interface with 64 (option 128) inputs and outputs is available to control automatic test systems.
Proven ibg standard and customized probes are available for all applications.
The eddyvisor® C is available as desktop version eddyvisor® DC (Desktop, Crack test) or as divided version as eddyvisor® C (Crack test) consisting of the operating unit eddyvisor® HMl (Human Machine Interface) and the measuring unit eddyvisor® MC.
The eddyvisor® C (Crack test) may be combined with the structure test instrument eddyvisor’S to eddyvisor® SC. Thus crack detection and structure test are realized in one instrument simplifying integration in automatic test systems.
