During the start-up process for the rate-of-turn sensor (DRS) the amplification of the amplitude (AF) of the operating signal (F(t)) is set to a constant pre-settable value (AFC) the stimulation frequency of the operating signal (F(t)) being essentially continuously raised from a starting value (f1) below the main resonance frequency of the oscillation movement to a final value (f2) above the main resonance frequency and below a spurious resonance frequency with simultaneous monitoring of the deflection (x(t)) and/or the speed (v(t)) of the oscillator element, in order to determine the main resonance frequency. After reaching the final value (f2) and the main resonance frequency determination, the stimulation frequency of the operating signal (F(t)) is set to the main resonance frequency and the operational regulation of the amplitude and the stimulation frequency of the operating signal (F(t)) released.

    摘要: A capacitive sensor includes a plurality of individual condenser elements, each of which consist of a first, preferably circular, electrode and a second, preferably surrounding ring-shaped, electrode, which are mounted on one side of a nonconducting support. A common conductor is connected to each of the first electrodes of condenser elements. A signal can be detected separately from each of the condenser elements via conductors connected separately to the individual second electrodes. To increase the sensitivity and to avoid interference, the remote side of the support opposite to the one side is provided with a third additional electrode, which is at ground potential and also acts as a shield for interfering couplings. The sensor is used for measurement of the fuel film thickness in the intake of an internal combustion engine.

    摘要: The invention relates to a method for unambiguously determining a physical parameter Φ using m phase-measured values αi with 1≦i≦m, whereby the phase-measured values αi have different, integer periodicity values ni and an integer periodicity difference (a) with Δn>1 within an unambiguous range E of the physical parameter Φ. A value T with (b) and (c) is calculated based on the phase-measured values αi and the periodicity values ni thereof, and, within a reduced unambiguous range Ered with (d), a value V is allocated to the value T by allocation according to (e), wherein TUk stands for a respective lower limit and TOk for a respective upper limit of T. The allocation intervals between the upper (TOk) and the lower limits (TUk) for T, as wells as the distances (f) correspond at least to the periodicity difference Δn. In order to determine the physical parameter Φ, value V is added up with the phase-measured values αi in a weighted manner.

    摘要: A method for triggering a heterodyne interferometer having two acousto-optical modulators in separate light paths, a receiver generating an analog signal and a downstream A/D converter converting the analog signal into a digital signal is described. The one acousto-optical modulator is triggered at a modulation frequency f1 and the other acousto-optical modulator is triggered at another modulation frequency f2, the difference between modulation frequencies f1 and f2 forming a heterodyne frequency fHet and the analog signal being converted into the digital signal in the A/D converter at sampling frequency fa. In such a heterodyne interferometer, a fixed ratio of modulation frequencies is maintained, and they are prevented from shifting due to aging and drift by forming at least two of the frequencies of modulation frequencies f1, f2 and sampling frequency fa from a fundamental frequency fqartz of a common oscillator. As a result, it is also possible for sampling frequency fa to be in a fixed phase ratio to the differential frequency of modulation frequencies f1, f2, of heterodyne frequency fHet. Measurement accuracy is increased because sampling is performed at a constant phase, independently of drift and aging.

    摘要: A device for distance measurement using a semiconductor laser in the visible wavelength range, which functions according to the echo time method, includes a collimation objective for bundling the transmitted measuring beam bundle, a circuit arrangement for modulating the measuring beam, a receiving objective for receiving and imaging the measuring beam bundle reflected at the distant object onto a receiving device, and an evaluation device for determining and displaying the distance measured to the object. The circuit arrangement for modulating the measuring beam and the evaluation device can be switched between two different operating modes. In the first operating mode, the modulation takes place using a first frequency and in the second operating mode using a second frequency. These frequencies stand in a whole-member ratio to each other. The reflected signal in the first operating mode is multiplied using a third frequency and in the second operating mode using a fourth frequency, before they are sampled for evaluation, in the first operating mode using a first sampling frequency and in the second operating mode using a second sampling frequency. In this context, the first sampling frequency is the difference between the fourth and the second frequency, and the second sampling frequency is a whole-number fraction of the second frequency.
