摘要： A pressure sensor for measuring a pressure difference between a pressure being measured and the ambient atmospheric pressure surrounding the pressure sensor, including a platform and a membrane loadable with a pressure being measured. The membrane is secured at its edge to the platform, with a pressure chamber thus being formed between the platform and the measuring membrane. The pressure chamber communicates over a reference air path with the atmosphere, with the reference air path being a winding path.

摘要： The sonic or ultrasonic transducer includes a circular piezo-ceramic disk capable of generating radial oscillations, and a metal ring, which embraces in tight close fitting relationship the circumferential surface area of the disk to form a radial oscillator in conjunction with the disk. The sonic or ultrasonic transducer formed in this manner has an emission surface corresponding to the entire surface area of the piezo-ceramic disk and metal ring, and displays a radial resonant frequency which is lower than that of the piezo-ceramic disk.

摘要： The invention relates to a pressure measuring cell comprising a base body, a membrane that is connected to the base body, thus forming a measuring chamber. During operation, the membrane is subjected to a deflection which is dependent on a pressure that is to be measured. The cell also comprises a membrane bed, formed by a surface of the base body that faces the membrane, at least one electrode being mounted on said bed. Said electrode, together with a counter-electrode that is mounted on the membrane, forms a capacitor, whose capacitance represents a measurement for the deflection of the membrane. The measuring cell is characterized in that the electrode is electrically connected through the base body and that the measuring chamber has a smooth surface in the contact zone, said surface having a contact pin that is guided in a bore through the base body. The electrode is electrically connected by means of said pin for measuring the capacitance and the pin is soldered into the bore on the membrane side, using a solder. The contact pin, the solder and the membrane bed form a smooth surface.

摘要： The acoustic transducer system includes a flexural vibrating plate coupled to an electromechanical transducer and so configured that it is stimulated to higher order flexural vibrations at the system operating frequency, at which nodal lines form on the flexural vibrating plate between which first and second antinodal zones are located oscillating alternatingly opposite in phase. For influencing the sound radiation, in the second antinodal zones oscillating in phase with respect to each other and opposite in phase in relation to the first antinodal zones one mass ring each is arranged on the rear side of the flexural vibrating plate facing away from the transmission medium concentrically to the centerpoint of the flexural vibrating plate. Due to the increased mass the second antinodal zones oscillate at a substantially smaller amplitude than the first antinodal zones so that the sound waves opposite in phase generated by the first and second antinodal zones are unable to fully cancel each other out, as a result of which a radiation pattern materializes having a pronounced directivity in the direction perpendicular to the flexural vibrating plate.

摘要： Evaluation unit of a differential-pressure sensor An evaluation unit of a differential-pressure sensor is provided which supplies an output signal which corresponds to a differential pressure (.DELTA.P) which has been corrected with respect to a measuring error due to the static pressure (P.sub.S). The differential-pressure sensor has a capacitive single-chamber differential-pressure measuring cell with two capacitors (4, 5) as sensor element (1), and a temperature sensor (6) is arranged at the sensor element (1). The differential-pressure measured value is corrected by means of a first correction value (.DELTA.K) which is a measure of the static pressure (P.sub.S) at a reference temperature (T.sub.R). This correction value (.DELTA.K) is determined from the difference between a sensor temperature (T.sub.S) determined by means of the temperature sensor (6) and a sum of a temperature discrepancy (T.sub.0) and an internal temperature (T.sub.i) assigned to the sum (.SIGMA.) of the reciprocal values of the capacitances of the two capacitors (4, 5).

摘要： The liquid atomizer consists essentially of an ultrasonic excitation system coupled with a narrow bending strip of so small thickness that it does not have sufficient inherent stability for linear alignment. In the case of excitation of bending waves with several essentially parallel, closely spaced nodal lines can be generated on the bending strip. Dimensional stability of the bending strip is achieved by at least one mechanical fixing devices and one prestressing device.
