摘要： A device (10; 20; 30) and a method for grinding a selected sample and presenting the sample for an analysis system (19; 29; 39). The device comprises a grinding chamber (11; 21; 31), a grinding means (12; 22; 32) for grinding the sample in the grinding chamber (11; 21; 31), and a pressing means (14; 24; 34) for compression of the sample in the grinding chamber (11; 21; 31). The grinding chamber (11; 21; 31) is preferably arranged to allow presentation of the sample for the analysis system while the sample is inside the grinding chamber (11; 21; 31).

摘要： In order to measure solid concentrations in liquids, the light from two differently modulated sources (Q1, Q2) directed on the liquid is measured at the same time and processed in a combined multi-beam measuring process consisting of a 90° light scatter (Q1, P, D4; Q2, P, D3) and back-scatter process (Q1, P1, D1; Q2, P3, D2) and the solid concentration is found therefrom. The process is suitable for the simultaneous measurement of both extremely low and extremely high solid concentrations by using a 90° light scatter process for low concentrations and a back scatter process for high concentrations. The multi-beam process which is based on 2 measurements through exactly the same window areas makes it possible effectively to compensate for undesired soiling of the window areas. Mechanical means for cleaning the window areas and to eliminate interfering light scatter are proposed.

摘要： Samples taken automatically and frequently from the outlets of silos (4) in mixing plants, e.g. for fodder mixtures, are brought unwrapped and successively to an automatic NIR analysing station (72, 26) through a pneumatic conveyor system with substantial common pipe stretches (36) between that station and the single samplers (34). The associated risk of contamination of the samples is counteracted by taking out and conveying sample portions which are much larger than what is required for the analysis itself, and the large sample portions are not wasted, as they are returned to their silos of origin through another pneumatic conveyor system (90). It is hereby possible to operate with a real on-line analysing and thus, with computer support, to effect required changes in the mixing recipes almost immediately in response to changed analysis results. Various specialized sample handling equipment for making the system operative is disclosed.

摘要： A cleaning device for cleaning an outer portion of a sensor includes: a pump connected to an air supply line; a pressure accumulator connected to the pump in a housing of the cleaning device, which can be mounted on the sensor; and an exhaust air duct with a pressure-controlled valve connected to the pressure accumulator and connected to at least one nozzle which is aligned on the outer portion to be cleaned. The cleaning device is configured to perform pressure-surge cleaning operations in which air drawn in by the pump is compressed in the pressure accumulator, and the compressed air in the pressure accumulator is expelled as a pressure surge via the at least one nozzle when pressure exerted by the compressed air enclosed in the pressure accumulator exceeds a pressure value required to temporarily open the pressure-controlled valve.

The cleaning arrangement comprises an external magnetic working platform, which is arranged coaxially to the symmetrical axis, is slidable in a translatory manner parallel to the symmetrical axis, is rotatable about the symmetrical axis, encloses the cylindrical measurement cuvette externally in an annular manner, and has at least one translatory magnet element and at least one rotary magnet element, and an internal magnetic cleaning unit, which is arranged within the measurement cuvette and is slidable in a translatory manner, has a cleaning body, has at least one translatory magnet element, and has at least one rotary magnet element. The translatory magnet elements as well as the rotary magnet elements of the working platform and the cleaning unit are coupled to one another in a contactless and magnetic manner, respectively. Other aspects are described and claimed.

摘要： A method for detecting a contamination of a cuvette of a turbidimeter. The turbidimeter includes a light source which emits a light beam directed to a cuvette, a scattering light detector, and a diffuser with a body and an actuator. The actuator moves the body between a parking position and a test position where the body is between the measurement light source and the cuvette, thereby interferes with the light beam, and generates a diffuse test light entering the cuvette. The method includes activating the actuator to move the body from the parking position into the test position, activating the light source, measuring a test light intensity received by the scattering light detector, comparing the test light intensity measured with a reference light intensity, and generating a contamination signal if a difference between a reference light intensity and the test light intensity measured exceeds a first threshold value.

摘要： Fouling of or damage to an electromagnetic radiation-transparent window can preclude one from obtaining satisfactory images with an image acquisition unit, such as a camera. Certain types of environments may be particularly prone toward promoting fouling or damage, and manual cleaning or repair of an electromagnetic radiation-transparent window may be difficult in some circumstances. These issues may be particularly prevalent when imaging drill cuttings and other solids obtained from a wellbore due to the complex sampling environment in which these solids are often disposed. Wellhead imaging systems can comprise: a flow pathway extending from a wellbore; an electromagnetic radiation-transparent window external to the wellbore establishing optical communication with the flow pathway; an image acquisition unit in optical communication with the flow pathway via the electromagnetic radiation-transparent window; and a movable barrier that is also electromagnetic radiation-transparent and is disposed between the electromagnetic radiation-transparent window and the flow pathway.
