20100295551 | DEVICE AND METHOD FOR INDUCTIVE MEASUREMENTS - SELF TEST - Method for nondestructive and noncontact detection of faults in a test piece, with a transmitter coil arrangement with at least one transmitter coil that transmits periodic electromagnetical AC fields to a test piece, a receiver coil arrangement with at least one receiver coil for detecting a periodic electrical signal having a carrier oscillation whose amplitude and/or phase is modulated by a fault in the test piece. A signal processing unit produces a useful signal from the receiver coil signal, and an evaluation unit evaluates the useful signal to detect a fault in the test piece. A self-test unit undertakes systematic quantitative checking of signal processing functions of the signal processing unit and/or of the transmitter coil arrangement and/or of the receiver coil arrangement and/or upon external request undertakes calibration of the signal processing unit using a calibration standard which replaces the transmitter coil arrangement and/or of the receiver coil arrangement. | 11-25-2010 |
20100295545 | DEVICE AND METHOD FOR INDUCTIVE MEASUREMENTS - SIGNAL RECONSTRUCTION - Method and device for nondestructive and noncontact detection of faults in a test piece, or electrically conductive particles in a liquid flow, moving past the device, using eddy currents. The test piece or flow is exposed to periodic alternating electromagnetic fields. A periodic electrical signal is detected by a receiver coil. The receiver coil signal has a carrier oscillation whose amplitude and/or phase is modulated by defects in the test piece or by electrically conducting particles and is digitized. A useful signal is produced from the digitized receiver coil signal, and the useful signal is evaluated with an evaluation unit to detect faults in the test piece or electrically conductive particles. When overdriving of the A/D converter stage by the receiver coil signal is ascertained, a part of the receiver coil signal truncated by the A/D converter stage is reconstructed using a mathematical approximation in the digitized receiver coil signal. | 11-25-2010 |
