Abstract: A method of the disclosure relates to detecting a measuring error during a measurement of a media property of a medium using a field device, wherein in a first step a measurement of a first media property is taken using the field device, wherein an electronic measuring/operating circuit provides a measured value of the first media property, wherein in a second step a second media property is measured using a sensor provided therefor, wherein the electronic measuring/operating circuit provides a sensor measured value, wherein in a third step a known relationship between the first media property and the second media property is used to calculate a second media property from the first media property, wherein in a fourth method step a statement about the functional capability of the corresponding sensor or measuring device is derived by comparing the sensor measured value with a calculation value.

Abstract: In a sensor assembly, a deformation body has two oppositely lying surfaces, an outer edge segment and a sensor blade extending from a surface outward. A protective apparatus protects the deformation body from pressure surges or abrupt changes of temperature on its surface. The protective apparatus includes at least one plate, extending radially inwardly so that a cavity is formed, which accommodates a region of the sensor blade adjoining the deformation body and remote from the distal end of the sensor blade, forming a gap between the plate and sensor blade. A sensor formed by the sensor assembly and a transducer element coupled therewith can be used for registering pressure fluctuations in a flowing fluid, such as steam having a temperature of 400 C and/or, a pressure of greater than 140 bar in order to measure flow parameters of the fluid.

Abstract: A measuring system comprises a measuring and operation electronic unit (ME) and a transducer device electrically coupled thereto. The transducer device has two tubes through which a fluid flows and causes to vibrate, a vibration exciter, two vibration sensors on the inlet and outlet sides, respectively, for generating vibration signals, and an inlet-side temperature sensor coupled to a wall of the tube for thermal conduction and an outlet-side temperature sensor coupled to a wall of the tube for generating temperature measurement signals. The measuring and operation electronic unit feeds electrical power into the vibration exciter in order to effect mechanical vibrations of the tube. Furthermore, the ME generates a mass flow sequence, by means of each of the vibration signals and each of the temperature measurement signals in such a way that mass flow measurement values are independent of the temperature difference.

Abstract: An apparatus for monitoring at least one physical or chemical process variable, comprising at least one measurement branch and a compensation branch connected in parallel therewith for compensating the influence of at least one environmental parameter on the process variable and/or on the measuring of the process variable. The measurement branch includes at least one primary sensor unit and a primary electronics unit for signal registration, evaluation, and/or feeding. The compensation branch includes at least a secondary sensor unit and a secondary electronics unit. The secondary sensor unit is so embodied that it registers a physical or chemical variable characteristic for the at least one environmental parameter, wherein the secondary electronics unit is so embodied that it draws the required energy from the measurement branch, and that it produces from the characteristic physical or chemical variable a compensation signal, which it transmits to the primary electronics unit of the measuring branch.

Abstract: A method serves for operating a measuring transducer of vibration-type having at least two oscillators, each of which is formed by a pair of measuring tubes, wherein the pairs of measuring tubes are arranged for parallel flow, wherein the two oscillators have mutually independent oscillator oscillations with mutually differing eigenfrequencies for corresponding oscillation modes. The method includes steps of determining a first value of a primary measurement variable, or of a variable derived therefrom, using the first oscillator, determining a second value of the primary measurement variable, or of a variable derived therefrom, using the second oscillator, checking an actual ratio between the first value and the second value by comparison with an expected ratio between the first value and the second value, and outputting a signal when the actual ratio does not correspond to the expected ratio.
