Rohmann ELOTEST PL600 Universeel digitaal eddy current test instrument

De recent geïntroduceerde PL600 is een stand-alone of volledig te integreren 19″ wervelstroomapparaat van de laatste generatie. Dit multi-techniek wervelstroom platform heeft een volledig digitale signaalverwerking en biedt verschillende methoden voor signaalexcitatie en signaalanalyse. Denk aan conventionele / klassieke wervelstroomtesten, pulserende magnetisering, harmonische analyse, etc.. Op basis van een modulair hardwareplatform en een aangepaste softwareconfiguratie kunnen alle soorten wervelstroomtesten worden uitgevoerd: scheurdetectie, warmtebehandeling, materiaalverwisseling en slijpbrandtesten. Zowel manueel, semi-geautomatiseerd als volledig inline!
