Abstract: A measuring cell (1) for the infrared analysis of fluids, in particular a measuring cell (1) having a permissible operating pressure of more than 20 bar and preferably more than 50 bar, has a flow channel (10) for the fluid formed between first and second elements (2, 4). Each element is transparent to infrared radiation at least in some sections. The infrared radiation can be radiated into the flow channel (10) by the first element (2) and can exit the flow channel (10) by the second element (4). The two elements (2, 4) are connected to each other in a fluid-tight and mechanically high-strength manner by a connecting layer (6) arranged between them and made of a glass-containing material, in particular a sintered glass-ceramic material. A measuring system (8) has that measuring cell (1). A method produces that measuring cell (1).

Abstract: The invention relates to a measuring cell (1) for the infrared analysis of fluids, in particular a measuring cell (1) having a permissible operating pressure of more than 20 bar and preferably more than 50 bar, having a flow channel (10) for the fluid that is formed between a first and a second element (2, 4), which are each transparent to infrared radiation at least in some sections, wherein the infrared radiation can be radiated into the flow channel (10) by means of the first clement (2) and can exit the flow channel (10) by means of the second element (4), and wherein the two elements (2, 4) are connected to each other in a fluid-tight and mechanically high-strength manner by means of a connecting layer (6) that is arranged therebetween and that is made of a glass-containing material, in particular a sintered glass-ceramic material; the invention further relates to a measuring system (8) having such a measuring cell (1) and to a method for producing such a measuring cell (1).

Abstract: The invention relates to a device (5) for measuring capacity, said device comprising an electrode arrangement consisting of a plurality of electrodes (E1, E2, . . . , En) which are adjacently and/or successively arranged on a carrier (6), an intrinsic measuring device (8) for measuring the capacitance between a first electrode (E2), in the form of a measuring electrode, and a second electrode (E1), in the form of a counter-electrode, and a controllable switching deice (7) for connecting the electrodes (E1, E2, . . . , En), in the form of first and second electrodes (E2, E1), to the measuring device (8) in such a way that they can be switched in a pre-determinable manner. The inventive device is characterised in that each electrode (E1, E2, . . . , En) of the electrode arrangement can be switched in a controlled, alternate manner by the switching device (7), in the form of a measuring electrode, and respectively at least one of the other electrodes (E1, E2, . . .
