摘要： A method of detecting the change in the structure of a turbine rotor (24) comprises injecting an ultrasonic signal into the turbine rotor (24) at a first position using a first ultrasonic transducer (102) to produce a diffuse field ultrasonic signal in the turbine rotor (24). Detecting the diffuse field ultrasonic signal in the turbine rotor (24) at a second position using a second ultrasonic transducer (106). Measuring the time for the diffuse field ultrasonic signal to travel from the first ultrasonic transducer (102) to the second ultrasonic transducer (106). Comparing the measured time for the diffuse field ultrasonic signal to travel from the first ultrasonic transducer (102) to the second ultrasonic transducer (106) with a stored time for the diffuse field ultrasonic signal to travel from the first ultrasonic transducer (102) to the second ultrasonic transducer (106) to determine if there is a change in the structure of the turbine rotor (24). Used to detect contact between the sealing members (74,76,78,80) of the turbine discs (26,28,30).

摘要： The invention relates to the non-destructive measurement of components, in particular, functional evaluation of the bonding of cast pieces, for example, pistons for internal combustion engines. On such a measurement or functional evaluation, the problem is to determine the functionality and integrity of the bonding between the base material and the cast or otherwise bonded material. The quality of the component or the suitability thereof for a particular application purpose can be determined and/or a quality control of the production process, for example, in the foundry or during production can be carried out. According to the invention, the above is achieved by means of a multi-stage correction method, by means of which measured values determined by a suitable embodiment of a measuring arrangement and method, for example, with ultrasound, are subjected to a multi-stage determination process, which minimises the interference factors inherent in the system on measurement in a universal manner for each single measurement, and thus determines the desired results. A system with a corresponding embodiment minimises error effects which occur on carrying out such a measurement (in particular, on adjustment/setting) as well as measuring errors and erroneous evaluation on carrying out the measurement, caused by geometrical tolerance deviations or differences in material or joint composition and further interference factors.

摘要： An ultrasonic interferometer for the characterization of the matter (solids, fluids & gases) in a medium is described, along with a method of using the same. The interferometer accurately determines the travel time of the multi-frequency ultrasonic signal in the matter that is being queried. By carefully selecting the design of the multi-frequency ultrasound signal, various properties of the material can be derived using a trainable classification system to classify or recognise the substance, or state of a process. The apparatus exploits the normally undesirable higher harmonics characteristics of the piezoceramic transducer to gain penetration through a spatial-frequency window that is not suitable for the higher frequency signals that are required to achieve the measurements.

摘要： The invention relates to a method and device for measurement of the specific density of a gaseous or liquid medium, whereby a pulsed acoustic signal (6) is injected into the measured medium by means of a transmitting transducer (2), the signal is detected by a receiver transducer (3), after passing over a measured path, whereupon the acoustic impedance Z is automatically determined in an analytical device (4) by comparison of a curve for the currently measured received signal with reference curves, predetermined for various values of the acoustic impedances stored for each value of the acoustic impedance, whereby the propagation speed c of the acoustic signal in the medium is determined and the density p of the medium is calculated as the quotient from the acoustic impedance Z and the propagation speed c. The method is preferably of application to an ultrasound mass flow measurement device and hence has the advantage that no additional density sensor is required, nevertheless permitting a robust and precise measurement of density.

摘要： The present invention is concerned with an on-line degradation monitoring for boiler tubes (15a,15b) in large combustion facilities, in particular waste incineration plants. The degradation of the tubes, in particular corrosion or caking, is determined in a more or less continuous manner while the combustion facility is operating, and thus not restricted to optical inspection during downtimes. A rate or accumulated degradation can be related to an operation mode of the facility. Appropriate degradation sensors (4) are arranged outside of a flue gas tract (14) where the boiler tubes are exposed to noxious flue gases from the combustion process, and receive ultrasonic signals from a space or volume within the flue gas tract (14). A test tube (40) is provided exclusively for the monitoring of the degradation progress and introduced into the flue gas tract (14) at a particularly corrosion exposed location.
