Abstract
A monitoring system monitoring electrical components of an apparatus for electrodynamic wall-thickness and defect testing includes a transmitter generating brief signals. An electrodynamic converter has a transmitter coil connected to the transmitter for receiving the brief signals and feeding the brief signals into a workpiece to be tested in which the brief signals are reflected. The electrodynamic converter has a receiver coil receiving the reflected signals. An amplifier is connected to the receiver coil for receiving the reflected signals and an evaluation unit is connected to the amplifier for receiving the reflected signals. At least one damping element and a delay line are connected to the transmitter for delaying and damping the brief signals. The delay line is coupled through the electrodynamic converter to the evaluation unit for feeding the delayed and damped signals to the transmitter coil.
