    Abstract: Erfahrungsgemäß ist eine Sensoranordnung zur Bestimmung einer Qualität und/oder eines Verschmutzungsgrades einer Flüssigkeit, insbesondere in einem Behälter, vorgesehen. Die Sensoranordnung hat zumindest einen Leitwertsensor, der dazu konfiguriert ist, einen Leitwert der Flüssigkeit zu bestimmen, und zumindest einen Kapazitätssensor, der dazu konfiguriert ist, eine Kapazität von zwei Messkörpern in der Flüssigkeit zu bestimmen. Des Weiteren weist die Sensoranordnung zumindest eine Recheneinheit auf. Diese ist dazu konfiguriert, die Qualität und/oder den Verschmutzungsgrad der Flüssigkeit unter Berücksichtigung der Messwerte des Leitwertsensors und des Kapazitätssensors zu ermitteln. Des Weiteren ist ein Verfahren zur Bestimmung der Qualität der Flüssigkeit mit der Sensoranordnung vorgesehen.

    CPC classification number: G01N25/18

    Abstract: A device for ascertaining a property of a fluid, having: an electric conductor assembly which is designed to be at least partly brought into contact with the fluid and which is designed as a voltage divider with two elements, wherein the first element is a first conductor which, at least in a current-conducting state, has a resistance value that differs from that of the second element; a measuring bridge with two voltage dividers connected in parallel, one of said voltage dividers being formed by the electric conductor assembly; an actuation unit for applying an AC voltage to the measuring bridge; a voltage detection unit for detecting a bridge voltage; and an analysis unit which is configured to ascertain a thermal conductivity as the property of the fluid by analyzing the bridge voltage using the 3-omega method.

    Abstract: A device for determining a hydrogen concentration or hydrogen mixture concentration includes: an electrical conductor arrangement which is designed such that it can be brought into contact with the fluid mixture at least in part and is realized in the form of a voltage divider having two elements, the first element being a first conductor which, at least in a current-carrying state, has a resistance value which is different from that of the second element, a measuring bridge comprising two voltage dividers connected in parallel, one of the voltage dividers being formed by the electrical conductor arrangement, a control unit for applying an AC voltage to the measuring bridge, a voltage detection unit for detecting a bridge voltage, and an evaluation unit configured so as to determine the thermal conductivity of the hydrogen or hydrogen mixture by evaluating the bridge voltage using the 3-Omega method.

    Abstract: A micro-fluidic pump (22) has a pulsating micro chamber (46) which includes a walled chamber (50). The walled chamber further includes at least one pulsating portion (52) actuable to pulse and change an interior volume of the walled chamber. An actuating mechanism (10) peristaltically moves fluids through a micro conduit (56). The actuating mechanism includes a closed pocket (11) adjacent to the conduit. A flexible mechanism (18) defines a portion of a wall of the micro conduit (56). An expanding mechanism (14) which is understood to be a fluid is disposed within the pocket (11) for expanding a volume of the pocket and thereby flexing the flexible mechanism (18) into the micro conduit thereby changing the volume of the conduit (56).
