Abstract: 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.

Abstract: A turbidity sensor and a method for determining at least one physical, chemical and/or biological measured variable of process automation in a medium by means of at least one optical sensor, comprising the steps of sending transmission signals into the medium, wherein the transmission signals are converted into received signals by interaction with, especially by scattering from, the medium as a function of the measured variable; receiving the received signals; and converting the received signals into the measured variable as a function of environmental conditions at the location of installation and, adjusting the sensor based on a calibration graph corresponding to environmental conditions at the location of installation.

Abstract: A contacting system, comprising: an essentially cylindrical contact body having at least a first opening, a second opening and a contact body interior between the first opening and the second opening. The first opening is embodied for accommodating the cable, wherein a holding element is provided in the contact body interior and is so embodied that it produces contact between the first conductor and the contact body. A sealing element is provided at the first opening and is so embodied that it seals off the contact body interior from the medium.

Abstract: A method for calibrating a sensor for measuring turbidity and/or solids content of a medium, wherein the sensor comprises at least one transmitting unit and at least two receiving units. The method comprises the steps of registering at least two measurement signals, which depend on the intensity of light scattered in the medium, wherein the light is sent from the transmitting unit and received by the receiving unit, abstracting the measurement signals to a feature vector, automatic selecting of a calibration model based on the feature vector, wherein the feature vector is transmitted to an earlier trained classifier and the classifier associates the calibration model with the feature vector, and calibrating the sensor with the automatically selected calibration model.

Abstract: Method for determining a measured value of a measured variable of a medium, by means of an optical sensor arrangement, which has at least one transmitter and at least one receiver, comprising the steps as follows: supplying the at least one transmitter with an exciter signal for producing an optical transmitter signal with a transmission signal strength, wherein the transmitter signal is converted by interaction with the medium as a function of the measured variable into a changed transmitter signal; producing a receiver signal from the transformed transmitter signal by means of the at least one receiver and registering a receiver signal strength of the receiver signal; conforming an excitation signal strength of the exciter signal based on the registered receiver signal strength for reaching a predetermined receiver signal strength; and registering the excitation signal strength required for reaching the predetermined receiver signal strength and determining the measured value therefrom.
