multi-frequency remote field eddy current detector

Description:

IDEA-ET/RFT intelligent all-digital multi-frequency, remote field eddy current detector 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, remote field 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.

IDEA-ET/RFT has a complete set of eddy current testing system. integrated with the conventional multi-frequency, multi-channel, far-field eddy current testing systems, it can also turns to be high-performance, multi-purpose, intelligent eddy current testing apparatus.

With four relatively independent testing channels, IDEA-ET/RFT can receive four absolute and four differential eddy current signals. via the soft swifching, the instrument can also be switched to be two dual-frequency eddy curent testing detectors with two simultaneous probe connections.The testing frequency is 50Hz to 10MHz with a variable frequency range for choices (far field:1HZ-10KHZ), 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 innder/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, IDEA-ET/RFT 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.
