摘要： A system and method of sensing in a system, the system comprising: a plurality of sensors (2, 4, 6, 8); and a processor (1); wherein each sensor (2, 4, 6, 8) has a resonant frequency dependent upon the value of a physical quantity being sensed by the sensors (2, 4, 6, 8); at least one of the sensors (2, 4, 6, 8) has a different resonant frequency from another of the sensors for a given value of the physical quantity; and the processor (1) is adapted to discriminate between the resonant frequencies of the sensors. Each sensor (2, 4, 6, 8) may be a fluid level sensor. Also, the range of fluid levels sensed by a first sensor (2) may be different to that sensed by a second sensor (4), wherein the first of the sensors (2) has a different resonant frequency to the second of the sensors (4).

摘要： The invention relates to a method and device for detecting the limit state of a material having a given dielectric constant. To this end, the invention uses a holding device, inside of which two electrically conductive rods are arranged. When a limit state is attained, said rods are immersed into the material to be monitored and are connected to an electric circuit. Said circuit generates high-frequency transmit pulses, which are fed to the rods via the line according to the principle of time-domain reflectometry. The signals reflected into the air by the boundary layer of the material are evaluated on the basis of their waveform.

摘要： Method and device for indicating movements of gas bubbles in a liquid, droplets of liquid in a gas or a level of liquid, the liquid or the gas forming a medium in a conduit (15) or a container. Microwave signals of a predetermined frequency are transmitted through a section (G) of the conduit (15) or the container (16) that is pervious to microwaves toward said medium, and microwave signals reflected from the medium are received. Received microwave signals are then utilized to indicate presence of gas bubbles, droplets, or a level of a liquid moving in said conduit (15) or said container (16). Said conduit (15) is designed with a section (G) that is pervious to microwaves, and a microwave transmitter (S) is provided to transmit microwave signals towards said section (G). A microwave receiver (M) is provided to receive microwave signals that are reflected from the medium, and said microwave receiver (M) is operatively connected to a detector (6).

摘要： L'invention concerne un dispositif et un procédé de détection de niveau par diffusion de micro-ondes. Elle propose de diffuser des micro-ondes dans le produit et de mesurer la puissance reçue sur un ou plusieurs récepteurs de micro-ondes. En présence de produit au niveau d'un récepteur, le récepteur reçoit les micro-ondes diffusées dans le produit.
La comparaison de la puissance sur le ou les récepteurs avec une valeur seuil permet une détection du niveau.
On assure ainsi simplement la détection d'un ou plusieurs niveaux, même dans des conditions très difficiles, comme par exemple pour des boues ou des eaux usées.

摘要： A level meter (10) includes a microwave transmitter (11), a microwave receiver (12) and a guide member (15) which is equipped with a port (23) for introducing a sample to be detected or with a guide body (219) made of a dielectric. The guide member is attached to a container (1) and connected at one end to the microwave transmitter (11) and at the other end to the microwave receiver (12) in such a manner that it extends into the container. The guide member serves to conduct a microwave (M) from the microwave transmitter (11) to the microwave receiver (12). When a sample enters the guide member (15) through the port (23) of the guide member (15), the propagation of the microwave (M) is interrupted. The microwave receiver (12) detects this interruption and indicates that the sample has reached a predetermined level. Alternatively, when the sample comes into contact with the guide body (219), the propagation quantity of the microwave (M) propagating through the guide body (219) changes. The storage level of the sample is detected by detecting this change quantity.

摘要： A technique for supervising a descending speed, thickness of a layer, particle size, and so on of charges in a blast furnace. Coke and ore composing the charges are detected by radiating an electromagnetic wave into the blast furnace. The supervision is utilizing the fact that an electromagnetic wave can easily pass through coke, but is reflected or scattered by ore.
