Abstract: A device, and corresponding method, for determining a presence of lead in a material composition of a pipe includes a probe, a resonant frequency measurement circuit, and a material analyzer. The probe includes an oscillator circuit and can be inserted into an interior cavity of the pipe and emit electromagnetic radiation. The frequency measurement circuit operatively communicates with the oscillator circuit and outputs resonant electromagnetic frequency measurement data indicating a resonant electromagnetic frequency of the oscillator circuit. The material analyzer receives the resonant electromagnetic frequency measurement data, and an additional measurement selected from the group consisting of (i) a measurement of power dissipation of the oscillator circuit and (ii) an interior diameter of the pipe, and outputs a positive or negative indication of whether lead is present in the material composition based on the resonant electromagnetic frequency measurement data and the additional measurement.

Abstract: The present disclosure discloses a method for detecting a natural frequency of a blade by a single blade tip timing sensor. In the method, two segments of displacement data vectors are subjected to dot product to obtain a product data vector after multiplication of corresponding serial numbers, the product data vector is subjected to low-frequency filtering, the filtered product vector is subjected to Hilbert transform to obtain an instantaneous phase, the instantaneous phase is subjected to discrete Fourier transform, an absolute value of a natural frequency difference between blades is extracted from amplitude frequency data, blades on a bladed disk are subjected to permutation and combination to obtain absolute values of the natural frequency differences between all the blades, a sum of the absolute values of the natural frequency differences between each blade and other blades is calculated.

Abstract: A defect detection method is provided for a pressurized pipe having at least one defect. According to the method, an acoustic source generates a probing wave of a frequency range from 10 kHz to 100 kHz, where the probing wave is scattered by the at least one defect to create a reflected wave; an acoustic receiver measures a wave response to obtain a measured response, where the measured response is attributed essentially to a superposition of the probing wave and the reflected wave; and a computer device processes the measured response to locate the at least one defect.

Abstract: A method for non-destructive testing of a quality of an ultrasonic weld from a welding process includes detecting of a time-dependent measurement value over a period of time, where the measurement value is characteristic of a mechanical or electrical vibration behavior of a welding process to be tested. The method includes evaluating a measurement-value course of the detected time-dependent measurement value by using a Fourier analysis. The method further includes comparing a result of the evaluation to a reference value in order to test the quality of the weld. A measuring device and an ultrasonic welding system are also included.
