Foerster MAGNATEST® D 3.623

• Processor-controlled testing system
• Single coil absolute operation, therefore no comparison coil required
• Optional adapter for two-coil differential operation
• Load-independent induction current, therefore constant induction current intensity and constant magnetic field strength during the testing
• High induction current intensity thus stimulation of higher harmonics and particularly high test sensitivity to the magnetic characteristics of the test material
• Single frequency or multi-frequency testing, Harmonics analysis
• Simple operator guidance thanks to application-specific function buttons and high resolution TFT colour screen
• Standardised interfaces for peripheral equipment (keyboard, mouse, printer, network, etc.)

Harmonic wave evaluation

Magnetische Prüfanlagen GmbH produces outstanding products for performant harmonic wave evaluations during structure testing. This makes it possible to reduce temperature and batch impacts as well as impacts of the test piece position and geometric component tolerances. The magnetization curve can be divided into carrier and harmonics (multiples of the carrier) using the Fourier transformation. The frequency spectra comprises all uneven frequencies, i.e. f1 (carrier), f3, f5, f7, etc. The evaluation of the harmonics provides additional information on the properties of the test material.
