Detects Variations in Alloy, Heat Treatment or Case Depth

  • Rapid sorting of ferromagnetic parts.
  • Offers choice of Polar (Vector) or Lissajou screen displays.
  • Inspect tubes or bars at production line speeds.
  • Choose any one of 10 pre-set frequencies from 10 Hz to 150 Hz.
  • Optional 8-channel multi-frequency software is available.
  • System can be set up and monitored on site or used via computer at a remote location.
  • Monitor presentation provides simultaneous display of the “standard” piece and test piece waveforms for easy comparison.
  • Test parameters, including filter, sensitivity, index gate and visible threshold levels, are selected using the keyboard or mouse while observing the effects on the display monitor.
  • All functions and test setup parameters in software can also be accessed through a computer LAN network.
  • Unlimited test setups can be stored on the hard drive for easy recall.

The Production Comparator VI is a Windows® based test instrument that uses low frequency electromagnetic techniques to inspect magnetic materials for variations in physical characteristics.

A frequent challenge in manufacturing and industry is how to separate different parts that have been intentionally—or accidentally—mixed. Electromagnetic comparators can be used to accomplish this quickly and economically.

  • This type of instrument “compares” variations in a test part to conditions in a known sample.
  • When a metal part is placed inside or near a test coil that is excited by an alternating current, the voltage output from the coil will be affected. This is the basic principle employed by all electromagnetic comparators.
  • The kinds of mixes that comparators will separate typically involve variations in alloy, heat treatment, hardness, structure, dimensions (including length) and certain other conditions.
