Abstract: A method for testing of a measuring device arrangement (1), the measuring device arrangement (1) comprising a measuring device (2) which, based on the determination of a measured quantity, generates an output signal which can be tapped from a pick-off site (3) as a pick-off signal. A method for monitoring a measuring device arrangement is devised that constitutes an inline test that does not interrupt the measurement or the transfer of the measured values is achieved in that an action is applied to the measuring device (2) such that the measuring device (2) generates a test signal as the output signal, and that the output signal and/or a signal which is dependent on it is influenced such that the pick-off signal is a definable setting signal.

Abstract: A level measuring system which operates according to the radar principle for measuring the level of a medium which is located in a vessel has a signal transmission apparatus for emission of an electromagnetic signal, an electronic apparatus which generates an electromagnetic signal, and a pressure-tight and/or diffusion-tight separating element. The electronic apparatus is made in several parts, one of which is a signal generating component. The signal generating component and another component of the electronic apparatus are made as independent units which are spatially separated from one another. There is a communication apparatus between the signal generating component and the other component, and there is a pressure-tight and/or diffusion-tight separating element between the other component and the signal transmission apparatus.

Abstract: A method for monitoring a transmitter that has a measurement unit and a transmission unit which are interconnected to each other in order to transmit signals. There is at least one connecting line for supplying power to the measurement unit which determines a measurement quantity and generates a measurement signal which is dependent on it. The transmission unit receives the measurement signal from the measurement unit, and based on the measurement signal, transfers an output signal to at least one signal transmission element. To provide a method for monitoring a transmitter which allows reliable displaying of an error as easily as possible and the shifting of the transmitter into a secured state, in the case in which the measurement unit detects the presence of an error state, the measurement unit acts on the connecting line.

Abstract: A method for monitoring a transmitter (1) with a measurement (2) and a transmission unit (3), with which a measurement (2) signal is generated that is dependent on a measurement quantity, and with the transmission unit (3) receiving the measurement signal, and based on the measurement signal, an output signal is transferred to a signal transmission element (4). To makes it possible to recognize an error, an input signal is taken from the signal transmission element (4) and is transferred to the measurement unit (2) as a comparison signal which corresponds to the input is compared with a stored signal and based upon the outcome of the comparison, either the measurement signal is transferred from the measurement unit (2) to the transmission unit (3) or the transmission unit (3) is shifted into a definable state and an error signal is transferred to it.

Abstract: A frequency synthesizer for generating a low noise and low jitter timebase of a reference signal generates first and second output signals a difference frequency that is low enough for use in sub-scanning is implemented with a first incrementer, having a preset increment and a preset end value E1 controlling a first fractional divider and a second incrementer having a preset increment and a present end value E2 controlling a second fractional divider, wherein each of the incrementers is clocked from the output signal of each fractional divider so that, when the end value E1, E2 is reached, an end signal is output and the incrementers are reset to a carryover value as a new starting value and the end signal is switched between the division factors of the fractional dividers so that the switching sequence of the end signal is periodic with the output signals of the fractional dividers.

Abstract: Method for operating a vortex flowmeter device for measuring the flow of a fluid that flows through a measuring tube in which a baffle is arranged for producing eddies in the fluid. A signal-processing device processes signals of first and sensors produced by pressure fluctuations. A first signal is obtained by multiplication of the signal of the first sensor with a correction factor, and the second signal is obtained by multiplication of the signal of the second sensor with another correction factor such that a wanted signal is obtained from the deviation between the first signal and second signals, and a sum signal is formed from the sum of the first and second signals. A correlation between the wanted signal and the sum signal is determined and the correlation is minimized by variation of the correction factors, whereby same-phase interfering signals superimposed on anti-phase sensor signals are at least minimized.
