FET-99A intelligent digital type eddy detector is suitable for online and offline detection of metal tubes、bars、wire rods、such as steel pipes、steel rods、electromagnetic wire 、copper wire、aluminum wire，it can apply to automatic detection of mechanic accessories ,equipped with relatively independent detecting channels so it can drive combined probes formed by absolute and differential coil .the detecting channel collect data simultaneously so as to detect longitudinal crack and transverse defect of metal bars、wire rods、and planks when they are producing. Having high sensitivity on longitudinal defect such as submerged joint and opening cracks and so on axial flaw。
scene pictures
It can detect crack created by malfunction during production。The signal got by detecting channel can make impedance plane diagram and time base showed on the screen. Suitable for all detecting requirements of mental 、wire rods、and so on 。And due to adopting full digitization design ,so it can build many standard detecting procedures and professional systems in the instrument。It’s convenient for users to use to change the specifications and be furnished with input and output control connector,convenient to detect connector of scene and many kinds of equipments ,and work together, forming a high degree automated entirety .
