摘要： An assembly for monitoring a predetermined level of a material in a container comprises two ultrasonic transducers mounted on the container in line with the level to be monitored, such that an interspace exists between the ultrasonic transducers into which the material enters on attaining the level to be monitored. The one ultrasonic transducer is an emitter transducer which at predetermined points in time for emitting ultrasonic pulses is energized by a frequency which is so low that the ultrasonic pulses are transmitted through the interspace to the detector transducer even when the interspace is filled with air. The other ultrasonic transducer is a detector transducer which converts detected ultrasonic pulses into electrical detection signals. To determine whether or not material is in the interspace between the ultrasonic transducers a check is made as to whether the detector transducer outputs after each point in time of emission a detection signal in a time interval corresponding to the transit time of the ultrasonic pulses from the emitter transducer to the detector transducer in air.

摘要： An arrangement for establishing and/or monitoring a predetermined filling level is described, in which a fixed phase difference (.DELTA..phi..sub.R), which is independent of the oscillation quality of the arrangement, exists between a transmission signal and a reception signal (E) at the resonant frequency of the mechanical oscillatory structure. This arrangement comprises a mechanical oscillatory structure (1) at least one transmitter (3), which excites the oscillatory structure (1) to produce oscillations, and two piezoelectric elements as receivers (24a, 24b). In accordance with a first variant, a first signal line (241a) of the first receiver (24a) is connected to an electrode which is arranged on a surface which bounds the first receiver (24a) in a direction opposite to its polarization. A second signal line (241b) of the second receiver (24b) is connected to the transmission signal line (5) via an electrical impedance (Z). The second signal line (241b) of the second receiver (24b) is connected to an electrode which is arranged on a surface which bounds the receiver (24b) in the direction of its polarization. The reception signal (E) is equal to the difference between the two electrical signals (E.sub.1, E.sub.2).

摘要： An assembly for sensing and/or monitoring the level of a material in a vessel includes a level sensor mounted in the vessel so that it comes into contact with the material when the material has attained a predetermined level. The level sensor contains a low-frequency sensing system and a high-frequency sensing system. The low-frequency sensing system is formed by a mechanical vibrator system induced to vibrate at its natural resonant frequency, and establishing whether the mechanical vibrator system is in contact with the material or not is achieved by evaluating the frequency and/or amplitude of the mechanical vibrations. For forming the high-frequency sensing system high-frequency elastic vibration is induced in a component of the level sensor, and establishing whether this component is in contact with the material or not is achieved by evaluating an electric signal generated as a function of the high-frequency elastic vibration.

摘要： For monitoring a predetermined level of a liquid in a container an ultrasonic transducer is fitted on the outer surface of the container wall at a measurement point situated at the height of the level to be monitored. The ultrasonic transducer when excited by an alternating voltage pulse having a given transmission frequency which equals the thickness resonant frequency of the container wall, transfers an ultrasonic transmission pulse to the container wall and converts ultrasonic vibrations, generated by reflected echo pulses, into electrical reception signals that are transferred to an evaluation circuit. In the evaluation circuit, on the one hand the presence or absence of echo signals is detected, and, on the other, the ultrasonic vibrations generated by the after-vibration of the container wall at the end of the transmission pulse are evaluated. As a result of this it can be determined with high error detection reliability whether the measurement point is covered by the liquid or not and whether the measurement arrangement is working satisfactorily.

摘要： A fill-level measuring device with a membrane, which is placed in such a manner on one of the two end region of a tubular housing that it seals the housing on such end region. An oscillatable unit is placed on the side of the membrane facing away from the housing, with a driver/receiver unit, which is composed of a plurality of piezoelectric elements arranged in a stack. The driver/receiver unit is placed via a pressure screw unit in such a manner in the housing that it oscillates in the direction of the longitudinal axis of the housing between the membrane and the pressure screw unit. The driver/receiver unit excites the oscillatable unit via the membrane to execute oscillations, with a control/evaluation unit, which evaluates amplitude, frequency and/or phase of the oscillations of the oscillatable unit and with a temperature sensor for determining temperature of the medium. The temperature sensor is integrated in a fill-level measuring device element, which is in thermal contact with the medium via the membrane or the housing, wherein the element is so selected that the oscillatable unit oscillates unimpaired by the temperature sensor.
