Description
Die Erfindung wird in der Messtechnik für Ölsorten und Ölzustände eingesetzt.The invention is used in metrology for oil grades and oil conditions.
Bekannt ist, den Zustand eines Öls zu ermitteln über die Lumineszenz /www.fluid.de/alterung-von-hydrauliköl-erkennen/, die optische Durchstrahlung/DE20 2014 1040594/www.process.vogel, die Ölqualität direkt im system messen/, die Viskosität und akustische Impedanz/Messung der Ölviskosität. elektronik industrie (2007)11, mit Gaschromatographen oder Massenspektrometer zu analysieren /DE10 2009052006/ oder Dielektrizitätskonstante und Wärmeleifähigkeit für die Zustandsermittlung zu nutzen /PCT EP02 03552/.It is known to determine the state of an oil via the luminescence /www.fluid.de/alterung-von-hydrauliköl-erkennen/, the optical transmission / DE20 2014 1040594 / www.process.vogel, to measure the oil quality directly in the system. viscosity and acoustic impedance / oil viscosity measurement. electronics industry (2007) 11, using gas chromatographs or mass spectrometers to analyze / DE10 2009052006 / or to use dielectric constant and thermal conductivity for condition determination / PCT EP02 03552 /.
Der Ölsensor SGM110 von BOSCH misst Temperatur, Viskosität, Leitwert und Permittivität. Der Ölsensor von DAIMLER ermittelt Permittivität und Viskosität. Für Frittieröle ermittelt das Messgerät FOM-320 von PCE Deutschland polare Anteile im erhitzten Öl. Der Ölsensor FPS2800B12C4 von TE sensor solutions misst Temperatur, Viskosität, Dichte und Dielektrizitätskonstante.The BOSCH SGM110 oil sensor measures temperature, viscosity, conductivity and permittivity. The oil sensor from DAIMLER determines permittivity and viscosity. For frying oils, the FOM-320 meter from PCE Germany determines polar components in the heated oil. The oil sensor FPS2800B12C4 from TE sensor solutions measures temperature, viscosity, density and dielectric constant.
All diese Messverfahren sind aufwendig und teilweise teuer, so dass es bisher keinen Sensor gibt, der allgemein z.B. in KFZ mit Dieselmotoren eingesetzt ist.All of these measuring methods are expensive and sometimes expensive, so that there is no sensor which is generally used e.g. used in vehicles with diesel engines.
Aufgabe der Erfindung ist deshalb, eine Anordnung zu finden, die mit geringen Mitteln und einfacher Konstruktion die Begrenzungen der oben aufgeführten bisherigen Lösungen weitgehendst egalisiert.The object of the invention is therefore to find an arrangement that largely equalized the limitations of the above-mentioned previous solutions with low resources and simple construction.
Die Erfindung ist dadurch gekennzeichnet, - dass Elektroden aus verschiedenen Materialien so zusammengefügt werden, dass sie elektrochemisch generierte elektrische NERNST-Spannungen liefern, wenn der zu ermittelnde Ölzustand kurzzeitig für ein zu wählendes Messintervall in einem Messvolumen über einen Temperaturimpuls auf eine erhöhte Temperatur gebracht ist. Die während dieser Zeit sich einstellenden NERNST-Spannungen werden zwischen jeweils zwei Elektroden, erweitert auch auf
Es wurde weiterhin erfunden, dass eine oder mehrere Elektroden selbst als Heizer eingesetzt werden können oder ein Heizdraht als Elektrode geschaltet ist. Bei Erhitzung durch einen Laserimpuls kann das Halbleiterchip ebenfalls als Elektrode eingesetzt werden.It was further invented that one or more electrodes can be used even as a heater or a heating wire is connected as an electrode. When heated by a laser pulse, the semiconductor chip can also be used as an electrode.
Die Elektroden können weiterhin als Messelektroden für eine Impedanzmessung mit Real- und Imaginärteil geschaltet sein, um weitere Merkmale für die Muster-bzw. Objekterkennung zu gewinnen. Das kann für verschiedene Temperatur- und Frequenzbereiche erfolgen. Damit stehen genügend Merkmale als Vektorkomponenten für eine Klassifizierung zur Verfügung, um den Alterungszustand von Ölen zu ermitteln. Der Messkopf muss dazu erfindungsgemäß nicht von seiner Konstruktion her verändert werden. Erfindungsgemäß ist auch, diese Anordnung für andere Zustandsbestimmungen von Objekten einzusetzen. Objekte in diesem Sinne sind alle nicht ölhaltige.The electrodes can furthermore be connected as measuring electrodes for an impedance measurement with real and imaginary parts, in order to obtain further characteristics for the pattern or image. Obtain object recognition. This can be done for different temperature and frequency ranges. Thus, enough features are available as vector components for classification to determine the aging state of oils. According to the invention, the measuring head does not have to be modified in terms of its construction. It is also according to the invention to use this arrangement for other state determinations of objects. Objects in this sense are all non-oily.
