FET-99 Full Automatic Tube And Bar Flaw Detection And Inspection System

Product Specification

System Description:
FET-99 Intelligent Digital Steel Bar Flaw Detector is suitable for on-line and off-line flaw detection of aluminum tubes, steel bars, stainless steel tubes, and can also be used for automatic flaw detection of other mechanical parts. The instrument adopts the latest digital electronic technology, eddy current technology and microcomputer technology, which is not only easy to debug and operate, but also has reliable, stable and sensitive flaw detection performance.
FET-99 has relatively independent test channels, which can drive different forms of detection probes, or a combination of absolute and differential coils, the detection channel at the same time for data acquisition, used to detect longitudinal cracks and transverse defects (e.g., spalls) in the production of metal tubes, wires and bars. When used for on-line inspection of wire, FET-99 has high sensitivity to axial defects such as dark intersections and open cracks.
FET-99 flaw detector with 64 Hz ~ 2MHz test frequency range, can adapt to a variety of different metal wire testing requirements, and because of the fully digital design, so can be built in the instrument a number of standard testing procedures or expert system, convenient for users to change the product specification call.
FET-99 can be equipped with a very low coupling gap requirements through the type of probe, can also be connected to only the size of a cigarette packet combination of flat probe or saddle-type probe. The instrument is suitable for almost all manufacturers of eddy current probes.
Detection process is generally as follows:
1, the probe is fixed.
2, steel pipe into the detection probe automatic detection.
3, there are defects when the automatic alarm and sprayed with color defects mark automatically to the unqualified box.
4, no defects without alarm and no spray mark automatically to the qualified box.
