The present disclosure relates to a calibration insert for the adjustment, calibration, and/or implementation of a function test of an optical sensor that is designed to measure at least one measurand in a medium by means of light, the calibration insert including: an inlet cross-section through which light enters into the calibration insert; an outlet cross-section through which light exits from the calibration insert; and at least one blocking element that is arranged between the inlet cross-section and the outlet cross-section, wherein the blocking element does not entirely let through the light, independently of its wavelength, from the inlet cross-section to the outlet cross-section. Instead, the blocking element partially absorbs, reflects, or scatters the light, wherein the ratio of the intensity of the light at the outlet cross-section to the intensity of the light at the inlet cross-section corresponds to a value of the measurand.

An arrangement for measuring process variables of a medium. The arrangement includes a housing embodied for accommodating a measuring apparatus for determining the physical and/or chemical process variable(s), wherein arranged in the housing is at least one window and at least the window contacts the medium, and wherein an oscillatory transducer is provided for transmitting sound waves, characterized in that the window is connected rigidly with the housing, the oscillatory transducer is arranged in a peripheral module having a module housing. The peripheral module is so arranged that the oscillatory transducer transmits the sound waves toward the window, wherein the sound waves pass through the module housing at an exit area, and the peripheral module is so arranged that medium is located in the region of the window and exit area.

A method is disclosed for determining a measured quantity, correlated with an extinction, in a medium, including the steps: radiation of light into the medium and measurement of the extinction after a first path length; radiation of light into the medium and measurement of the extinction after a second path length, wherein the first path length differs from the second path length; and determination of the measured quantity correlated with the extinction using the extinction after first path length and extinction after second path length. Additionally disclosed is a sensor arrangement for execution of the method.

The present disclosure relates to a sensor arrangement for determining the turbidity of a liquid medium. The sensor arrangement includes a sensor section with at least one light source for sending transmission light into a measuring chamber, and at least one receiver associated with the light source for receiving reception light from the measuring chamber, wherein the transmission light is converted into the reception light in the measuring chamber by the medium by means of scattering at a measurement angle, and the reception light received by the receiver is a measure of the turbidity. The reception light is back reflected at a reflection element in contact with the medium, whereby an optical path from the light source through the measuring chamber to the reflection element and from the reflection element through the measuring chamber to the receiver results.

Sensor arrangement for determining turbidity

A turbidity sensor or an arrangement for optically measuring one or more physical, chemical and/or biological, process variables of a medium. The medium is located in a pipe. The arrangement includes a housing and the housing is embodied for securement in the pipe. The housing is embodied for accommodating at least one light source for sending light through a window region into the medium and at least one light receiver for receiving light through the window region from the medium. The light is scattered by the medium and the light intensity received by the light receiver is a measure for the physical, chemical and/or biological, process variable, characterized in that the light source is so arranged that the light propagates in the medium in the longitudinal direction of the pipe.

A method for determining a turbidity of a medium in a container using at least one turbidity sensor. Depending on the ambient conditions at the installation location of the turbidity sensor, comprising the following steps: passing transmitted radiation through the medium, wherein the transmitted radiation is converted by interaction with the medium, as a function of the turbidity in the received radiation; receiving the received radiation; converting the received radiation into a scattered light intensity, and determining the turbidity from the scattered light intensity. The method is characterized by the following steps: detecting the chronological sequence of the scattered light intensity; determining a mean value on the basis of the chronological sequence of the scattered light intensity; determining the turbidity from the mean value using a calibration model by assigning a turbidity to each mean value; determining a corrected mean value on the basis of the chronological sequence of the scattered light intensity, by determining a noise parameter from the scattered light intensity, and by determining the corrected mean value from the noise parameter using a noise model, and determining a corrected turbidity at least from the corrected mean value using the calibration model by assigning a corrected turbidity to each corrected mean value. The invention further relates to a turbidity sensor for implementing the method.
