Abstract: The present disclosure relates to a diagnostic device for a field device from the field of automation technology, comprising a control unit, a sensor carrier, a stereo acoustic sensor, which is fastened to the sensor carrier, a first temperature sensor, which is fastened at a first position on the sensor carrier, and a second temperature sensor, which is fastened at a second position on the sensor carrier. The first position and the second position are remote from one another owing to a first spacing. The sensor carrier is suitable for being expanded such that the first spacing is changed.

Abstract: The invention relates to a diagnostic device (1) for a field device from the field of automation technology, comprising a control unit (2), a sensor carrier (3), a stereo acoustic sensor (4), which is fastened to the sensor carrier (3), a first temperature sensor (5), which is fastened at a first position (P1) on the sensor carrier (3), and a second temperature sensor (6), which is fastened at a second position (P2) on the sensor carrier (3). The first position (P1) and the second position (P2) are remote from one another owing to a first spacing (A12). The sensor carrier (3) is suitable for being expanded such that the first spacing (A12) is changed.

Abstract: The present disclosure relates to a method for determining missing and/or incorrectly positioned field device components of a field device using a stored field device configuration, comprising: creating a digital image of the field device, extracting at least one object and its position in the field device from the image, comparing the object and its position with stored images of field device components and their positions in a field device, identifying the object as a field device component and its position based upon the comparison, determining a field device configuration using the identified field device component and its position in the form of a digital code, comparing the determined field device configuration with the field device configuration of the stored image, and determining the missing and/or incorrectly positioned field device components based upon the comparison.

Abstract: The present disclosure relates to an automation technology process control system for controlling at least one field device having an electronic measurement and/or operation unit, including a user interface for operating the electronic measurement and/or operation unit of the at least one field device, characterized in that the at least one user interface is designed as a tangible user interface.

Abstract: A sample preparation system for an analytical system for determining a measured variable of a sample liquid, comprising: a transport unit connected with a sample taking location via a first fluid conducting line; a sample collecting unit, which serves the analytical system as a staging area for automated removal of liquid samples, based on which the measured variable is determined; a filter unit arranged between the sample taking location and the transport unit; and at least one reservoir connected via a second fluid conducting line with the filter unit for providing a cleaning medium for cleaning the filter unit; wherein the transport unit is embodied to transport sample liquid from the sample taking location through the filter unit into the sample collecting unit. The cleaning medium includes an oxidizing agent.

Abstract: The invention refers to a device for taking samples from municipal and/or industrial wastewater that contains a filter (3) and which may be connected to a pressure pipe that carries fibers and particles. For a device, which is designed in a robust and cost-efficient way, while, at the same time, showing a long-lasting service life, the cylinder-shaped filter (3) has been positioned inside of a housing (2), with a hollow space (9) arranged between the housing (2) and the filter (3) that allows for the filter (3) to be washed around, with the filter (3) having a pore size of less than 50 ?m, preferably between 0.5 and 20 ?m.

Abstract: The invention relates to a method for encoding items of information and to a device and method for evaluating the encoded information. A prior art method for marking and providing objects with items of information and data involves the creation and use of bar code. With the inventive method, it is now possible to provide objects with a more sophisticated and higher data density than that provided by prior art methods. By using fluorescent dyes, an additional encoding word is added to the coding language, this coding language having been available up to now and being composed of a sequence consisting of black and white bars, thereby increasing the depictable data density. The inventive device enables the decryption of encrypted and compressed items of information, which have a higher data density than that of prior art encoding methods. To this end, an opto-electrical reading unit is equipped with means that control the emission of light.
