摘要： In order to excite Lamb waves in a plate or container wall, an IDT transducer (interdigital transducer) is employed. The IDT comprises a layer composed of piezoelectric material, and on one of whose surfaces two electrodes which engage in one another like fingers are applied. The IDT is acoustically coupled to the plate or container wall by means of the surface facing away from the electrodes. If a radio-frequency AC voltage is applied to the connections of the electrodes, then a thickness vibration is initiated in the piezoelectric layer. If the speed of propagation or speed of sound of the longitudinal waves which result in this thickness vibration in the piezoelectric layer is matched to the phase velocity with which a s0 mode Lamb wave propagates in the material of the plate or of the container wall then only s0 mode Lamb waves are initiated by the resonance effect in the plate or container wall, by virtue of the acoustic coupling between the piezoelectric layer and the plate or container wall. The matching process can be carried out by selecting the distance (D) between the fingers of the electrodes such that this distance (D) is equal to half the wavelength &lgr;/2 of the thickness vibration to be initiated in the piezoelectric layer.

摘要： This level measuring instrument which operates with microwaves, has a radiation characteristic with a pronounced forward lobe and can be used to transmit and/or receive microwaves with a large frequency bandwidth. A housing section is designed as a waveguide short-circuited at one side and one end by a rear wall, and is virtually completely filled with an insert made of a dielectric. An exciter element, projects into the housing section and is connected to a microwave source. An antenna adjoins the housing section, for transmitting and/or receiving microwaves. A gap is arranged in the insert between the exciter element and the antenna. The gap forms a filter which is essentially non-transparent to higher modes of the waveguide.

The device has a signal-generating unit, which generates electromagnetic measuring signals, a transceiver unit, which emits the measuring signals via an antenna in the direction of the surface of the filling material and which receives the echo signals reflected at the surface of the filling material, the antenna comprising a waveguide which widens in the direction of emission into a cavity of a defined shape, and an evaluation unit which determines the filling level in the container from the propagation time of the measuring signals. At least one dielectric filling material is provided which at least partially fills up the waveguide, and which virtually completely fills up the widened cavity of the antenna.
