摘要： For the identification of the resonance characteristics of a piezo-electric transducer, an input signal having a variably selectable frequency is divided into two sub-signals of the same frequency to be tuned to one another, one of said sub-signals being independent of and the other thereof being dependent upon the electro-mechanical properties of a piezo-electric tranducer under test. A difference output signal is generated from the two sub-signals, this difference output signal being measured relative to a reference output signal derived from the input signal. The tuning of the two sub-signals in the measurement is undertaken constantly to zero and with a rated value actual value differential control of that part of the difference output signal lying in phase or, alternatively, 180.degree. out of phase with the reference output signal. The remaining part of the difference output signal which is phase-shifted 90.degree. relative to the reference output signal, is used as a measure of the resonance characteristic of the transducer.

摘要： A measuring chamber for photo-acoustical sensors for the continuous measurement of radiation-absorbing substances, in particular of radiation-absorbing particles, in gaseous samples includes at least one entry and at least one exit for the samples, a tube section with microphone that allows for the flow-through of the sample in longitudinal direction, and at least one entry and exit point for a laser beam that is aligned with the tube section, and whereby these entry and exit points are both arranged at a distance from the measuring tube by at least one chamber with a cross-sectional area that is expanded relative to the tube section. To prevent soiling of the windows at the points of entry of the radiation into the cell and to slow down the deposition of the particles of the measured aerosol, whereby long-term, high-sensitivity operation of the measuring cell is possible, two entries (2, 3) are envisioned at two ends of the tube section (31) that are opposite relative to each other and at least one exit (4) that is arranged at a location which is centered between the entries (2, 3).

摘要： A transducer comprising a flexible piezoelectric layer as a sensor element for measuring mechanical quantities in hollow bodies, above all pressures in pipes, the opposite sides of this layer being bonded to electrically-conductive contact layers and being connectable via leads to a display and evaluation unit. In order to achieve a high temperature stability in such transducers and to make them suitable for use at temperatures exceeding 80.degree. C., the piezoelectric layer is proposed to consist of wurtzite or sphalerite. One of the electrically-conductive contact layers can be of some heat-resistant, flexible supporting material, for instance flexible metal foil, such as Cu-Be foil, or a sheet of plastic, one or both of whose sides are metallized, and the other electrically-conductive contact layer can be a metal coating applied by evaporation.

摘要： For operating an electromechanical transducer system with at least one piezoelectric transducer element, if necessary at least one identification element and an electronic control unit, on the one hand, the wanted signals of a certain utility operating range defined by the frequency band and time window thereof, assigned to at least one piezoelectric transducer element, as well as, on the other hand, inquiry signals and response signals for the functional testing of the transducer system are transmitted via a line system with only one electrical signal line.In order to thereby render possible a simple and reliable diagnosis method for the input circuit of cable break, with a corresponding increase in operational reliability, reduction of error search times and simplification of operation, at least one inquiry signal located outside the utility operating range of the transducer element is transmitted to the transducer system and from the resulting response signal at least one characteristic value is formed and at least one previously determined criterion is queried, wherein in the event of non-fulfillment of the criterion, an error message is generated.

摘要： The life of a sensor unit is very strongly dependent on the loading of the sensor unit during use. The life of a sensor unit is generally specified in a number of loading cycles, however, which does not take into consideration the loading of the sensor unit. The invention therefore specifies a method and apparatus for assessing the residual life of a sensor unit which takes into consideration the actual loading of the sensor unit and therefore the residual life of the sensor unit can be estimated more precisely by virtue of a damage factor (S) being determined for the loading of a loading cycle (B) and the loading cycle (B) being weighted therewith.

摘要： An ultrasonic gas flowmeter includes a measuring pipe with flowing gas, transmitting and receiving sound transducers, transmission and reception electronics, and evaluation electronics. The sound transducers (7, 8, 9, 10) are designed as capacitive electro-acoustic ultrasonic transducers to construct a flowmeter with improved capacity, especially in view of temperature stability and the reduction and consideration of a temperature profile. Devices (5, 6) are provided to level the gas temperature profile and to minimize the influence of the temperature profile on the flow measurement. A more accurate and dependable detection of the volume flow or the mass flow of gases is to be achieved, especially in highly dynamic flows, for the method of determining the flow of gases whereby the mean flow velocity is determined and the flowing gas quantity is determined with highly synchronized resolution from the two transit times of two acoustic signals. In addition, an assessed value is computed (35) for the flow after the determination of the transit times and the assessed value is corrected at least by means of a characteristic temperature of the gas and the temperature of the wall of the measuring pipe (36).

摘要： A sensor containing at least one piezoelectric transducer element is operated via a common, single signal line in both possible operating modes--first, at low frequencies as a measuring element for a mechanical quantity upon utilization of the direct piezoeffect and, second, at higher frequencies as a piezoelectric resonator upon utilization of the inverse piezoeffect for electrical excitation of mechanical oscillations and of the direct piezoeffect for generating the piezoelectric reaction. A high-frequency signal (u.sup.HF, u.sub.F) that describes the resonant characteristic and a lower-frequency signal (u.sub.NF, u.sub.Q) that describes the mechanical influence are generated from the measured signal on the signal line. The faultless function of the sensor together with the appertaining measuring amplifier, for example, can thus be monitored immediately during a measurement with the sensor or a simultaneous measurement of two different quantities can be undertaken.
