Embodiment Construction

[0077] figure 1 A measuring arrangement 10 is schematically depicted, comprising a first measuring device 1 , a second measuring device 2 and a control device 3 which can be designed, for example, as a multi-channel measuring transducer. In the present example, the measuring device 1 is an in-line measuring device which is integrated in the processing container and which is used to capture the measured variable of the measuring medium contained in the processing container to carry out the processing. In this example, the measuring medium is a measuring liquid. The first measuring device 1 detects measured values ​​of the measurand with fast measuring cycles, such as >60 per minute; however, it exhibits a strong cross-sensitivity to the influence of disturbances such as changes in the composition of the process medium. The first measuring device 1 can, for example, comprise an in-line probe as a measuring sensor. In the present example, the measured variable to be monitored b...

Abstract

A measuring apparatus for determining at least one measurand of a measuring medium includes a first measuring device including a first measuring sensor structured to contact the measuring medium and configured to detect measured values of the at least one measurand, the first measuring device embodied to determine a first measured value that is dependent on the at least one measurand of the measuring medium, a sampling device structured to remove a sample from the measuring medium, a second measuring device including a second measuring sensor and embodied to determine a second measured value that is dependent on the least one measurand of the sample, and an electronic control apparatus configured to receive and process the first and second measured value and to perform a verification, calibration and / or adjustment of the first measuring device using the second measured value.

Description

technical field [0001] The invention relates to a measuring device for determining and / or monitoring at least one measured variable of a measuring medium, in particular a measuring liquid. Background technique [0002] In order to determine the composition of the measuring medium, in particular of liquids such as pure liquids, liquid mixtures, emulsions or suspensions, various analytical measuring devices are used in the measuring procedures of the process. An analytical measurement device generally comprises a sensing element designed to generate a measurement signal based on at least one analytical measurand and measurement electronics to determine from the measurement signal a measured value representing a current value of the at least one analytical measurand in the measurement medium. The analytical measurand can be, for example, the concentration or activity of an analyte or a parameter which depends on the concentration or activity of at least one analyte in the measu...
