Austenitic / nonmagnetic rods
Austenitic rods, particularly stainless steel, have low permeability. This presents special requirements for the eddy current test systems:
DEFECTOMAT: The DEFECTOMAT product family is used for testing material surface of austenitic rods for point and transverse defects.
CIRCOGRAPH: The test systems have rotating test heads developed for the detection of longitudinal surface defects. They scan the test material in a helical path and without making contact.
FOERSTER also provides the MAGNETOSCOP, MAGNETOMAT, and KOERZIMAT MS measuring instruments for measuring permeability and magnetic flux density as well as saturation polarization.
