Detailed Product Description ET20P dual channel intelligent eddy current flaw detector is a new generation of eddy current nondestructive testing equipment, it has adopted the most advanced FPGA, DSP digital electronic technology, eddy current technology and micro processor technology, multi-channel real-time detection technology, can effectively detect ferromagnetic and non ferromagnetic metal tube of outer wall defects and real-time.The DSP/FPGA high speed data processing circuit, ensure the high sampling rate and low noise instrument, preventing the false or false positives.ET20Padopts advanced eddy current impedance plane and scanning technology design, not only convenient to debug and operate, and with reliable, stable and sensitive detection capability.ET20P has two relatively independent detection channels, which can simultaneously obtain two absolute or two differential eddy current signals.Or by the combination of the absolute and differential coil probe, two detection channels for data acquisition at the same time, for the detection of metal tubes, rods in the production of longitudinal cracks and transverse defects (such as the barge port).

With ET20P 64HZ ~ 5MHz the adjustable frequency range, it has very high detection for production in the process of welding, crevice, opening cracks, porosity, slag and folding defects sensitivity.The instrument is suitable for nondestructive testing of various kinds of metal materials, such as copper, aluminum, low conductivity stainless steel, titanium alloy and so on. For steel, iron and other ferromagnetic metal also has excellent detection performance.
With different forms of probe (such as the external wear, flat type and fan probe), can be online or offline fast detection of circular, square or other types of cross section of the tube and bar. Instrument is in line with GB, DIN, ASTM, API and BS and other international eddy current testing standards.
