摘要： A monitoring procedure for monitoring the quality of measurement spectra of a liquid medium continuously determined with a spectrometric sensor, which spectra in each case reproduce spectral values in a specified measurement wavelength range, is described with which: for each measurement spectrum, a quality parameter of the respective measurement spectrum is determined in each case based upon at least one characteristic value calculated in each case based upon the spectral values of the respective measurement spectrum, wherein each characteristic value for each measurement spectrum is determined in each case based upon the spectral values of the respective measurement spectrum in a range, specified for the respective characteristic value, of the measurement wavelength range, and, based upon the quality parameters, those measurement spectra which have spectral values that are impaired by a disturbance are identified as outliers.

摘要： An optical measuring system for determining a measured variable in a medium includes a light source and a container with medium. The light source radiates measuring light into the container on a first light path, wherein the measuring light is converted into reception light as a function of the measured variable and radiates reference light past the container on a second light path. A diffusion disk is arranged between the container and a receiver, wherein the diffusion disk is configured and arranged such that the reception light impinges on the receiver through the diffusion disk. The diffusion disk is configured such that the reference light impinges on the receiver through the diffusion disk. The receiver receives the reception light and the reference light, and a data processing unit connected to the light source and to the receiver determines the measured variable from the measuring light and the reception light.

摘要： A calibration attachment for adjusting, calibrating, and/or performing a functional check of an optical sensor, which is configured to measure at least one measured variable in a medium by light, wherein the sensor is designed to emit transmitted light of at least one wavelength in the range of 200-700 nm, in particular 200-500 nm, includes a housing and a body, which is arranged in the housing, wherein the body includes praseodymium and cerium, and wherein the body, after excitation with the transmitted light, emits light of a different, in particular longer, wavelength. A sensor arrangement includes such a calibration attachment and use thereof.

摘要： A preparation method for preparing spectrometric determinations of a measurand in a target application using a spectrometer is provided. On the basis of reference data recorded in the target application, a normalized measurand master spectrum with a spectral distribution characteristic of the measurand is determined. On the basis of the measurand master spectrum, synthetic spectra are generated which cover a value range greater than or equal to a value range covered by the reference values. On the basis of the synthetic spectra, information for carrying out the spectrometric determinations, including information comprising a property, a wavelength range, and/or a path length range for an optical path length suitable for carrying out the spectrometric determinations, and/or comprising a calculation rule, with which, on the basis of measurement spectra in the target application, measured values of the measurand are determined.
