摘要： A micro-system, for example a micro-sensor, comprises a resonator 10 with vibrating element(s) 11 receiving an excitation signal E of a loop 20 for automatic gain control, as a function of an amplitude setpoint (C) and providing as output a signal y(t) defined by a peak amplitude having a nominal value A0 dependent on the said setpoint and a resonant frequency. The micro-sensor integrates a circuit for measuring a quality factor of the resonator based on a measurement of an attenuation of the output signal during a momentary phase of cutoff of the excitation signal E applied to the resonator. This circuit for measuring the quality factor is configured so as to activate the excitation signal cutoff phase, for a duration of cutoff Td such that at the end of the cutoff phase, the peak amplitude of the output signal is attenuated by factor to the nominal peak amplitude A0 at the start of the cutoff phase, by a factor k with 1

A first end of the pressure sensitive unit is connected to a central area of a second surface of the diaphragm. A second end of the pressure sensitive unit is connected to the housing. The detecting axis is approximately orthogonal to the pressure receiving surface. A circumference of a portion where the central area and the first end of the pressure sensitive unit are in contact with each other is located inside a circumference of the central area. A thickness of the central area is larger than a thickness of an area surrounding the central area.

摘要： A conduit (106), with geometry designed to enhance pressure sensitivity, is vibrated at resonance in two modes along different cross-sectional axes (a, b). Measuring the change in the frequency ratio squared of the modes yields a substantially linear relationship to pressure that is substantially immune to other material properties and other environmental factors. Moments of inertia in different cross-sectional axes are related to pressure as a result of the elliptical or oral cross section of the conduit (106).

摘要： A time difference signal having a pulse width corresponding to the time difference between an output of a resonant pressure sensor and a reference clock is prepared. The pulse width of the time difference signal is expanded by a given magnification. Based on a count value obtained by counting the reference clock during the expanded pulse width and a count value obtained by counting the reference clock during one cycle of the output of the resonant pressure sensor or a period which is integer times as long as the one cycle, the output frequency of the resonant pressure sensor is obtained. It is possible to obtain the fast processing and the high resolution without increasing the frequency of the reference clock.

摘要： The present inventions overcomes a drawback that although it is necessary to increase frequency of a reference clock to perform the measurement of output frequency of a resonant pressure sensor speedily with high resolution, the increase of frequency gives rise to an increase of the power consumption and hence, the use of a two-wire differential pressure/pressure transmitter is difficult. A time difference signal having a pulse width corresponding to the time difference between an output of a resonant pressure sensor and a reference clock is prepared. The pulse width of the time difference signal is expanded by a given magnification. Based on a count value obtained by counting the reference clock during the expanded pulse width and a count value obtained by counting the reference clock during one cycle of the output of the resonant pressure sensor or a period which is integer times as long as the one cycle, the output frequency of the resonant pressure sensor is obtained. It is possible to obtain the fast processing and the high resolution without increasing the frequency of the reference clock.

摘要： In order to determine parameters of closed containers, primary mechanical oscillations are excited in a container wall. The secondary oscillations which are excited in the container by the primary mechanical oscillations of the container wall and which occur within the space between a closure and the liquid are picked up and analyzed, the parameters being determined from the ascertained frequency characteristic of these oscillations. In addition, the primary oscillations of the closure can also be picked up and analyzed, the internal pressure prevailing in the container being determined from the frequency of these primary oscillations. The frequencies of the primary and secondary oscillations can be determined by analysis of the frequency spectrum. The secondary oscillations can be picked up separately from the primary oscillations in that only those oscillations are picked up which occur within a time measurement window within which the primary oscillations have already decayed.
