The amplification factors of the output amplifier and the input amplifier are tunable. The control unit tunes the amplification factor of the output amplifier as a function of damping of the mechanically oscillatable unit in such a manner that the amplitude of the electrical, input signal lies within an amplitude band and that the amplification factor of the output amplifier decreases in the case of lessened damping by the medium and increases in the case of greater damping by the medium, and the control unit tunes the amplification factor of the output amplifier and the amplification factor of the input amplifier in such a manner that the total amplification factor of the electronics unit equals a predeterminable value.

    摘要: An apparatus for ascertaining and/or monitoring a process variable, especially density of a medium. The apparatus includes: an exciting/receiving unit, which excites a mechanically oscillatable unit to execute mechanical oscillations and which receives the mechanical oscillations; an electronics unit, which applies to the exciting/receiving unit an electrical, exciter signal, and which obtains from the exciting/receiving unit an electrical, received signal. The electronics unit produces the exciter signal in such a manner, that, between the received signal and the exciter signal, a phase difference equal to a desired value of phase difference results, at which effects of changes of viscosity on mechanical oscillations of the mechanically oscillatable unit are negligible, and that the desired value of phase difference is predetermined as a function of the ratio of impedance of the exciting/receiving unit to the input impedance of the electronics unit.

    摘要: An apparatus for determining and/or monitoring at least one process variable of a medium. The apparatus includes: at least one mechanically oscillatable unit; a driving/receiving unit, which, starting with an electric, excitation signal, excites the mechanically oscillatable unit to execute mechanical oscillations, and which receives the mechanical oscillations of the mechanically oscillatable unit and converts them into an electric, received signal; and an electronics unit, which, starting with the electric, received signal, generates the electric, excitation signal and sends it to the driving/receiving unit. The electronics unit is embodied in such a way that it generates the excitation signal, such that a predeterminable phase difference exists between the excitation signal and the received signal. Present in the electronics unit is at least one all-pass filter for tuning the phase difference.

    摘要: Parking brake, in particular for a wheelchair, with a pressing element (10) articulated by a pivoting lever (8) coupled to a retainer (12) mounted to the wheelchair frame. The pivoting lever (8) is tiltable by swiveling a hand brake lever (7) into an engaged position, in which the pressing element (10) exerts force against a wheel (2). In addition, a resetting-force-applying element is set under a pre-load against the pivoting lever (8) to return the pivoting lever (8) to a neutral position when the hand brake is released, characterized by the fact that the resetting-force-applying element is a flexible bendable element (6) formed from a frame cover (5) fastened to the retainer (12).

    摘要: An actuating means adapted for fluid activation has a contractile hose terminally secured by clamping on at least one head piece. The contractile hose fits into an annular clamping gap or nip, whose wall bears saw tooth serrations, the saw tooth serrated areas being so arranged that their teeth are radially opposite each other and arranged in pairs each at the same level. The outer saw tooth serrated area is located on a compression sleeve, which is radially pressed to join it with the hose end section surrounded by it.

    摘要: The invention relates to a method and a device for determining and/or monitoring the fill level (F) of a medium in a container or, respectively, to a method and a device for establishing the density (ρ) of a medium in the container. The invention allows a highly accurate determination or monitoring of the fill level (F) or the density of a medium in a container. With reference to the method, the object is solved in that the influence of at least one disturbing parameter on the oscillation frequency of an oscillation-capable unit is established and correspondingly compensated in the determination of the fill level (F) of the medium in the container or, respectively, in the determination of the density (ρ) of the medium in the container.
