Description

ET40D Dual-Frequency & Four-Channel & Intelligent Eddy Current Detector is a new generation of eddy current nondestructive testing equipment, it adopts the most advanced FPGA,DSP digital electronic technology, eddy current technology and micro processor technology, multi-channel real time detection technology can detect ferromagnetic and non ferromagnetic metal pipe inner wall and the outer wall defects effectively. The DSP/FPGA high speed data processing circuit, ensure the high sampling rate and low noise instrument, preventing the false or false positives. ET 40D with two independent detection channels and two independent adjustable detection frequenc,can get two different frequencies reflect the differential, absolute vector signal, detection and wall thickness measurement at the same time. ET40D used advanced eddy current impedance plane and timebase technology design, not only debugging and operation, and is reliable, stable and sensitive detection capability.
