摘要： A level measuring device suitable for highly accurate measurements. A transmission pulse generator generates microwave pulses at a transmission repetition rate and transmits them through an antenna towards a material whose level is to be measured. Echo signal from the surface of the material are received by the antenna. A reference pulse generator generates reference pulses similar to the transmission pulses but at a reference repetition rate which differs from the transmission repetition rate by a small frequency difference. The echo signal and reference pulse are input to a first mixer which generates an intermediate frequency signal that, with respect to the echo signal, is slowed by a time dilation factor equal to the quotient of the transmission repetition rate and the frequency difference. A first subcircuit samples the intermediate frequency signal, the time interval between two successive samplings equaling a time unit. A differential signal generator generates a differential signal which changes with the frequency difference. A second subcircuit determines the period of the differential signal on the basis of the time unit. An evaluation unit determines an actual time interval between two points of the echo signal corresponding to the two sampling points.

摘要： The transducer supply is configured for supplying a passive transducer arranged in an explosion-hazard zone with electrical energy from a DC voltage source. The electrical energy is transmitted via a two-wire connection, via which in the opposite direction the measured value sensed by the transducer is transmitted by the transducer setting the direct current obtained from the DC voltage source to a value variable between two limit values. As a means of protection a transformer is inserted in the two-wire connection which affects DC decoupling. The direct current is chopped in accordance with the principle of a DC voltage converter at the primary side of the transformer and re-rectified on the secondary side. To permit connection of an active transducer instead of a passive transducer, the active transducer having its own energy supply and furnishing at its output connections a direct current in a quantity representing the measured value, an adapter circuit controlled by the output current of the active transducer is inserted between the output connections of the rectifier circuit and the connecting terminals provided for connecting the active transducer, this adapter circuit loading the rectifier circuit with a direct current which is proportional to the output current of the active transducer.

摘要： The electronic switching device serves to control the connection of a load to a voltage source by a switch which is controlled in a first operating mode directly by a binary signal furnished by a signal processing circuit and in a second operating mode inverted. The switching device has three terminals, of which the first permanently remains connected to a first terminal of the voltage source and to a first terminal of the load, whilst of the other two switching device terminals the one is connected to the second terminal of the voltage source and the other to the second terminal of the load. The switching device is configured so that it can be changed over from the one operating mode into the other by interchanging the connections between these two other switching device terminals and the second terminals of the voltage source and of the load, respectively.

摘要： The determination and/or monitoring of a predetermined material level in a container is effected with the help of a material level sensor which contains a mechanical oscillatory structure, an electromechanical excitation transducer and two electromechanical reception transducers. The mechanical oscillatory structure is secured at the height of the predetermined material level in such a way that it comes into contact with the material when said material reaches the predetermined material level. Each reception transducer is connected to the input of an assigned circuit channel, which contains an amplifier circuit, the output of which is connected to the excitation transducer and which is so constructed that the mechanical oscillatory structure is excited to produce oscillations with its natural resonance frequency. The two circuit channels are activated alternately by means of a control circuit. Furthermore, each circuit channel contains a measuring signal transducer which produces a measuring signal which on the one hand contains the information about the frequency of the output signal of the amplifier circuit, and to which on the other hand an identifier assigned to the circuit channel has been added, said identifier being different from the identifier assigned to the other circuit channel.
