Multifect-GX

Multifect-GX with its harmonic analysis is an ultimate tool in the hands of the quality control manager.

Highly advanced multi-frequency, multi-channel, multi-parameter eddy current comparator with real-time harmonic analysis and built-in Industry 4.0 support

Overview

Multifect-GX is a sixth-generation versatile multi-frequency, multi-channel, multi-parameter eddy current comparator for segregation of metallic components and raw stock. The  system outshines old-school instruments by implementing real-time analysis of harmonics of each test frequency. This enables sorting of components previously impossible with conventional instruments. The system is ideally suited for stringent quality checks of crucial automotive

Multifect-GX can test parts at up to 32 frequencies at one go. Components up to nine harmonics can simultaneously be analyzed for each frequency. Harmonics carry information about non-linearity of B-H curve of a material.

Applications

  • Sorting of bars or components according to alloy type
  • Sorting of fasteners according to hardness
  • Segregation of forgings as per heat-treat condition
  • Evaluation of gudgeon pins for case-depth
  • Regression readout of values ( e.g. Hardness )
  • Confidence Testing with known good samples
  • Artificial Neural Network based grouping
  • Segregation with multiple parameter mixups
  • Harmonic analysis for ferromagnetic materials

WHY HARMONICS?

Harmonics carry key information about the metallurgy of components

Ferromagnetic materials exhibit hysteresis in their magnetizing curve.  Remanance, Coercivity values are important pointers to the metallurgy of the material.  So also the area enclosed by the curve.  When a sinusoidal excitation is applied to a non-ferromagnetic material, flux density is also sinusoidal.  In case of ferromagnetic material  the flux density has distortions.  Voltage induced in pickup coils is a time-differential of this distorted flux density curve.  This has harmonic content which depends on the non-linearity of the B-H curve.  Typically hard materials have higher hysteresis, and result in higher harmonic content in the signal, and can be easily sorted out by analyzing the harmonics.  It must be noted that say testing at the third harmonic of 100 Hz signal is NOT the same as testing at 300 Hz at all.
