With this issue, ibg is signaling a new generation of eddy current test instruments, which I believe set new standards in structure and crack detection technology for the testing of components.

Under the generic name of eddyvisor®, these instruments represent a new family for us, of which different models will be available, customized for each crack detection and structure test application. This issue is intended to introduce the primary models and inform you of some facts about these new and pioneering instruments.

As always, if you have questions, or if you are interested in configuring an instrument system to fit a specific situation, I'm available for consultation and elaboration. I'll look forward to hearing from you

Meanwhile, you can chat with us at our show booth at the Quality Expo at Chicago's Rosemont Expo Center on April 19-21; or the Heat Treatment Show in Pittsburgh on September 27-28, and we can fill you in on the new eddyvisor®, or systems for any other eddy current component testing application you may have in mind.

I hope I see you there.

HIGH-SPEED applications for new eddyvisor®


Using four test coils at the same time enables non-destructive testing up to 18,000 parts per hour for correct heat treatment (hardness, case depth, hardness location, etc.).


Each cam and journal are tested for correct heat treatment. Up to 32 different test locations (tolerance fields) may be verified by the eddyvisor® in a very short time.

Monitoring of hardening process

Test table to monitor several induction-hardened zones on four different drive shafts. The test result is available within a fraction of a second, and is completely documented.

ibg's new standard for production and laboratory operations: eddyvisor®

Almost daily, demand for improved non-destructive testing in the production of automotive components increases. Of course, quick and reliable testing is important, but also required are complete documentation of test results and ease of implementation and operation.

A new generation of instruments has arrived: the eddyvisor® fulfills the requirements demanded by automotive producers, and it also offers additional features for optimizing testing and reducing costs in the production process.

An instrument for two modes of operation:
production and the laboratory

Two models of the ibg eddyvisor® will be available.

The production version of the eddyvisor®involves the eddyvisor® HMI,which is considered a "Human Machine Interface," and the eddyvisor® MS, which stands for Measuring unit and Structure test.

The eddyvisor® HMI and the eddyvisor® MS may be installed separate from each other, as they are cable-connected. The eddyvisor® HMI has been designed for integration into automated production lines.

eddyvisor HMI can have up to 32 test channels.

A user-friendly instrument, the HMI unit may be installed near an operator, always visible for viewing, while the measuring unit can be installed in a switch cabinet or near the test coils.

The desktop version, designated the eddyvisor®DS (D= Desktop, S= Structure), is most suitable for flexible tasks in a laboratory, for audit testing, or for small-to-medium- production testing. This instrument is equipped with up to 16 test channels.

Converting the instrument from one part type to another takes only seconds, once tolerance fields are stored in the unit.
