摘要： For safety reasons the potential of an electrical supply line of a radar sensor should be separate from the potential of the filling level container. An arrangement for potential separation for a filling level radar is provided, which arrangement comprises a separation element for insulating the waveguide from the antenna. The separation element, corresponding to the cross section of the waveguide, is ring shaped. In this way rotatability between the sensor housing and the antenna subassembly is provided without influencing the signal line between the antenna and the waveguide.

摘要： Both in potential separation in the microwave path, and in potential separation directly between the two-wire loop and the output circuit, the quality of signal transmission may be negatively affected. A filling level radar device with potential separation within the electronics unit is stated, wherein potential separation does not separate analogue signals but instead separates digital signals or direct-current-free alternating signals. For example, the separation line leads through digital signal connections or alternating-voltage signal connections. As a result of this the expenditure for potential separation may be reduced and the transmission quality may be improved.

摘要： A combination includes a feedthrough element for an electric high-frequency signal in a TDR level metering device, and a probe for guiding the high-frequency signal from the feedthrough element to the filling product surface of a filling product to be measured and back. The feedthrough element includes at least one guiding element (6), into which the electric high-frequency signal is to be fed at an inlet point (10), and which transmits at an outlet point (17) the electric high-frequency signal to a probe (7) adapted to guide the high-frequency signal, a one-part or multipart mechanical carrier element (1), and a one-part or multipart insulation (11, 12) present between the carrier element (1) and the guiding element (6). In the combination the impedance of the feedthrough element and the impedance of the probe (7) following the outlet point (17) are substantially matched to each other at the outlet point (17).

摘要： A level transmitter for use in a process application measures the height of a product level in a container, e.g., in a tank. The level transmitter includes an electromagnetic wave antenna directed into the tank. An electromagnetic wave source sends an electromagnetic wave signal through the electromagnetic wave antenna. An electromagnetic wave receiver receives the reflected electromagnetic wave signal. Measurement circuitry coupled to the source and receiver initiates transmitting of the electromagnetic wave signal and determines product level height based upon the received, reflected signal. Output circuitry transmits information related to product height. The device is suitable for use with containers having very small orifices for antenna insertion.

摘要： Described is a method for automatically initiating an update of a parasitic echo storage device in a fill level meter operating according to a runtime method. In this method individual echoes of echo curves of different ages are allocated, according to their typical echo characteristics, to global echo groups so that subsequently, after examining the behaviour over time of the echoes of the respective global echo curves, it can be judged whether the echoes of the respective global echo curves are useful echoes or parasitic echoes. Starting from this classification, the parasitic echo storage device is then updated with the oldest echoes of the corresponding global echo groups. Apart from the method for updating a parasitic echo storage device described is also an evaluation device for implementing the method as well as to a computer program and a computer program product for carrying out the method.
