HEF-24ET intelligent all-digital multi-frequency eddy current
testing instrument is a new generation of eddy current
non-destructive testing device, With the adoption of the most
advanced digital electronic technology, multi-frequency eddy
current technology, and microprocessor technology, it can achieve
effective inner wall and outside wall cracks detection of the
ferromagnetic and non- ferromagnetic metal pipes in real time.
HEF-24ET has a complete set of eddy current testing system.
integrated with the conventional multi-frequency, multi-channel,
conventional eddy current testing systems, it can also turn to be
high-performance, multi-purpose, intelligent eddy current testing
apparatus.
With four relatively independent testing channels, HEF-24ET can
receive four absolute and four differential eddy current signals.
via the soft switching, the instrument can also be switched to be
two dual-frequency eddy current testing detectors with two
simultaneous probe connections. The testing frequency is 50Hz to
10MHz with a variable frequency range for choices, and it has the
function of weak testing signals amplification and strong
anti-jamming capability. Applied to the tube cracks testing, with
inner-through probe, it can easily detect the defects such as
inner/outside wall surface crack, pits, corrosion, thinning, wall
materials and internal defects. And it has the feature of
computer-controlled auto-testing, digital display, high testing
sensitivity, stable performance and so on.
Therefore, HEF-24ET particularly suitable for various in-service
metal (copper, titanium, aluminum, zirconium and other metal
material) tubes and metal parts flaw detection and wall thickness
measurements and evaluation analysis in nuclear energy, electric
power, petrochemical, aerospace, aviation and other departments.
More detailed, such as the testing of before service or in service
boiler tube, heat exchanger tubes, underground pipes and cast iron
pipes etc.
