eddyvisor® C Eddy Current Test Instrument 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 test instrument 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.
In the field of crack and grinder burn detection, the need for trained experts to
perform the sophisticated and time consuming tasks of manual determination and
setting of suitable filter band, phase angle and gain is eliminated by ibg’s exclusively
developed Preventive Multi-Filter Technology (PMFT), which automatically creates
tolerance zones by simply scanning good parts. This quantum leap in eddy
current technology, unique to ibg worldwide, establishes a new standard for quality
in crack and grinder burn detection by the eddy current method.
During material data recording (calibration) with PMFT, surface areas of several
good parts are scanned. The good surface eddy current “noise“ is recorded
simultaneously in each of 30 band pass filters. Tolerance zones, enveloping 360
degrees, are automatically created within each filter band, capturing the
allowable eddy current “noise“ from good parts. Good part noise signals result from
allowable variations in surface roughness and material properties. Thus, the thirty
tolerance zones store the part specific fingerprint of the good parts. Edge effects,
hardness profile run out, eccentricity, etc. of the good parts are calibrated during
material data recording. Thus, pseudo rejected parts are reduced considerably without
losing visibility to real flaws in parts.
The unique “good-part-only-concept“ enables setup within a few minutes. Simply
scan and record an adequate number of good parts. Tolerance zones within each of
the 30 PMFT filter bands are automatically generated capturing the allowable noise
from the good parts to form good part finger prints in each of the 30 PMFT filter
bands. After material data recording, one key press switches to Preventive MultiFilter Test, and the test can start. Done! Faster starting yet more reliable eddy
current testing is not possible.
