Description

ET 20P 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. ET 20P adopts 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 barge port).
