摘要： The invention relates to a vibration sensor having an oscillating unit (2) which consists of a membrane (3) that has an inner surface (4) and an outer surface (5) and optionally at least one oscillating element (6) fixed to the outer surface (5) of the membrane (3), a transmitter/receiver unit (7) being provided, which excites the oscillating unit to oscillate with a predetermined excitation frequency and to receive the oscillations of the oscillating unit (2), and a control/evaluation unit (8) further being provided which signals when the predetermined fill level is reached or determines the density and/or the viscosity of the medium. In order to be able to use the vibration sensor in the high temperature range, a disk-shaped element (9) made from a magnetostrictive material is provided and is force-locked on the inner surface (4) of the membrane (3). The transmitter/receiver unit (7) is an electromagnetic drive.

摘要： The invention relates to an apparatus for determining and/or monitoring at least one process variable of a medium (1), in particular of a density, a viscosity or a filling level of the medium (1) in a container (3), with a mechanically oscillatable structure (5, 27) having at least one oscillation property that is dependent on the process variable, with an electromechanical transducer (9, 25) having at least one piezoelectric element (7, 7a, 7b), which transducer excites the structure (5, 27) to mechanical oscillations using an excitation signal (S) supplied to the transducer (9, 25) and converts the resulting oscillations of the structure (5, 27) into a receive signal (E) which corresponds to a superposition of the excitation signal (S) and a useful signal (N) representing the oscillation, with a reference element (13) to which the excitation signal (S) is supplied parallel to the transducer (9, 25) and via which a reference signal (S
R ) that corresponds to the excitation signal (S) and is independent from the oscillation is tapped, and with an electronics system which extracts the useful signal (N) on the basis of the receive signal (E) and of the reference signal (S
R ) and which determines and/or monitors the process variable on the basis of the useful signal (N), which comprises, for automatic measurement of the temperature of the transducer (9, 25), a temperature measuring device which supplies to the transducer (9, 25) and to the reference element (13) during temperature measurement operation an auxiliary signal (H), the frequency (f
H ) of which is outside a frequency range prespecified by a resonant frequency (f
r ) of the oscillation structure (5, 27), and which determines a temperature (T) of the transducer (9, 25) on the basis of the useful signal (N) extracted during temperature measurement operation.

摘要： The invention relates to a method for determining a ratio of an adsorbed material which is contained in a shaped body, granulate or powder comprising a zeolite, a zeolite compound or silica gel as an adsorber material. The invention is characterized in that in the event that the adsorber material is in the form of a shaped body (1), at least two electrodes (2) are applied spaced apart from each other on a surface (3, 4, 5, 6) of the shaped body (1) and/or solidly inserted into the shaped body (1), that in the event that the adsorber material is in the form of a powder or granulate (9), a corresponding shaped body (1) made of the same material is permanently introduced into the powder or granulate (9), that the electrodes (2) are charged with an alternating current, wherein an electrical parameter is determined and that the degree of saturation of the adsorber material is determined on the basis of the parameter.

摘要： The invention relates to a method for producing a measuring device (1) for determining and/or monitoring a process variable of a medium in a container (2), with a mechanically oscillatory unit (5), which can be fastened via a fixing device (20) to a sensor housing (15) and/or to the container (2), and with a driving/receiving unit (25), which sets the mechanically oscillatory unit (5) in oscillatory motion or receives the oscillations of the mechanically oscillatory unit (5). According to the invention: the mechanically oscillatory unit (5) is set in oscillatory motion; reaction forces and/or reaction torques are detected, which act upon the fixing device (20) via the oscillations of the mechanically oscillatory unit (5); a message is output when the reaction forces and/or reaction torques exceed predeterminable limit values, and; in the event a message is output, the mechanically oscillatory unit (5) is altered with regard to its oscillation properties. The invention also relates to a corresponding device and to a measuring device (1) itself.

摘要： The invention relates to a device for determining and/or monitoring the level of a filling material in a container. According to the invention, an oscillatable unit (2) is provided which is fastened to a membrane (5), whereby said oscillatable unit (2) is mounted at the height of the predetermined level. An emitting-receiving unit (6) is provided which, with a given emit frequency, causes the membrane (5) and the oscillatable unit (2) to oscillate, and which receives the oscillations of the oscillatable unit (2). A control/evaluation unit (10) is provided, which identifies once the predetermined level is obtained upon a given change in frequency or which, with the aid of the oscillation frequency of the oscillatable unit (2), determines the density of the filling material.

The fastening unit is connected directly or, optionally, via another element to the container inside of which the medium is located. The tube (2) surrounds the inner oscillator (3), and the inner oscillator (3) is fastened to an end (7), which is oriented toward the process and which is located at the end (6) of the tube (2) also oriented toward the process. The drive/receiving unit (8) sets the mechanically oscillatory unit (1) in oscillatory motion or it receives the oscillations of the mechanically oscillatory unit (1). The invention provides that the inner oscillator (3) has at least one groove/narrowing (9) that determines at least the oscillation frequency of the mechanically oscillatory unit (1).
