SPINNING OR ROTARY EDDY CURRENT TESTERS

SPINNING OR ROTARY EDDY CURRENT TESTERS In rotary probe technology, the product under test moves longitudinally through the rotating test probes resulting in a helical search pattern. As the probe passes over a defect, variations in the induced eddy current pattern are detected. The minimum flaw length which can be consistently detected is a function of the rotary speed of the probe and the throughput speed of the material. Similar results can be obtained by holding the test probe stationary and rotating the material past the probe. For rotary testing of hot material, the Rotomac® BQ hot tester is available.Current MAC rotaries feature continuously variable high speed rotaries ( 1800 – 6000 RPM) , and multi-probe headplates to detect shorter defects without sacrificing throughput speed. Similar results can be obtained by holding the test probe stationary and rotating the material past the probe. Rotary testing is the method of choice for detecting seam type surface defects in non-magnetic and magnetic grades of wire and bar. MAC has rotary mechanics for up to 7-1/ 2 inch ( 191mm) diameter material.The MultiMac eddy current instrumentation operates with MAC rotaries where long, continuous defects may not be adequately detected by encircling test coils.Typical applications for rotary test sensors are: • Detect seam type surface defects in cold drawn wire or cut length bar stock • Inspect in line with continuous wire operations such as wire drawing, parts forming, re-spooling, or straight and cut • Inspect cut lengths, usually off-line • Test parts, such as small shafts and bearings for longitudinal surface defects Distributor agent menjual service repair jasa perancangan perbaikan dan upgrade alat, sensor dan sistem Inspeksi eddy current test system, ultrasonic tester, flux leakage inspection system, Multiple & Custom NDT Systems: inspeksi quality check keretakan automotive parts for cracks, alloy, and heat treatment, bearing races for cracks, aluminum sheet for inclusions, US Army ordnance parts for cracks, rail testers ( M A Nordic) , dll.
