EEC-35RFT Dual Frequency Far Field Eddy Current Tester Operation Manual

The EEC-35RFT dual frequency far-field eddy current testing instrument is a new generation of eddy current non-destructive testing equipment. It adopts advanced FPGA DSP digital electronic technology, far-field eddy current technology and microprocessor technology, multi-channel real-time detection technology, and can effectively detect the inner and outer wall defects of ferromagnetic metal pipelines in real time. During detection, it is not affected by probe lift off, skin effect, uneven conductivity and magnetic permeability. The EEC-35RFT has multiple optional detection programs, a multi window display mode on the same screen, and displays the phase, amplitude changes, and amplified waveforms of multiple eddy current signals on the same screen. Multiple relatively independent detection channels with a wide frequency range, adjustable from 5 Hz to 5 MHz. Multiple mixing units can suppress interference signals generated by support plates, dents, deposits, and cold processing of pipes during in-service testing, eliminate false and true, and improve the evaluation accuracy of eddy current testing signals. And due to the adoption of fully digital design, standard testing programs can be established within the instrument, making it convenient for users to call during on-site testing. Equipped with tube sheet drawing software for eddy current testing planning, statistics, data storage, indexing, calling, archiving, and archiving of in-service pipelines.
