Description
Die Erfindung betrifft einen Sensor nach dem Oberbegriff des Patentanspruchs 1.The The invention relates to a sensor according to the preamble of the claim 1.
Derartige Sensoren werden zur Messung von Meßgrößen in der Hausgeräte- und Haustechnikindustrie verwendet. Insbesondere sind diese Sensoren für Haushaltsgeräte, wie Waschmaschinen, Geschirrspülmaschinen o. dgl., bestimmt.such Sensors are used to measure measured variables in household appliances and appliances Building services industry used. In particular, these sensors are for home appliances, like Washing machines, dishwashers o. The like., Determined.
Viele Anwendungen, in denen Flüssigkeiten bewegt werden, erfordern neben der Erfassung der Durchflußmenge die Messung von Druck, Temperatur und Verschmutzungsgrad des Fluids. Bei Heizanlagen beispielsweise dienen Durchflußmenge und Temperatur des umgewälzten Heizwassers der Regelung der transportierten Wärmemenge, während der Druck ein Maß für den Füllgrad des Kreislaufes und die Funktion der Umwälzpumpe ist. Für Zwecke der vorausschauenden Wartung benötigt man zusätzlich den Verschmutzungsgrad des Heizwassers, damit man das Heizwasser wechseln kann, bevor zu viele aggressive Partikel und andere Verunreinigungen einzelne Bauteile wie Ventile lahm legen können.Lots Applications where liquids move be required, in addition to the detection of the flow rate Measurement of pressure, temperature and degree of contamination of the fluid. For heating systems, for example, serve flow and temperature of the circulating heating water the regulation of the amount of heat transported, while the pressure is a measure of the degree of filling of Circulation and the function of the circulation pump is. For the purpose of anticipatory maintenance needed one additionally the degree of contamination of the heating water, so that the heating water can change before too many aggressive particles and other impurities Individual components such as valves can shut down.
Für die einzelnen Meßfunktionen wird bisher eine Anordnung von einzelnen Sensoren mit zugehörigen Meßkomponenten verwendet, von denen jeder einen Kabelanschluß mit Stecker benötigt. Für die Messung von wenigstens zwei Meßgrößen sind somit wenigstens zwei Meßkomponenten mit elektrischen Wandlerelementen als Bestandteil der Meßkomponenten zur Umwandlung der jeweiligen Meßgröße in ein elektrisches Signal notwendig. Die Kosten sind daher beträchtlich und stehen dem Einsatz in preiskritischen Anwendungen im Haushalt- und/oder Konsumsektor entgegen.For the individual Measurement functions So far, an arrangement of individual sensors with associated measuring components used, each of which requires a cable connection with plug. For the measurement of at least two measured quantities thus at least two measuring components with electrical transducer elements as part of the measuring components for converting the respective measured variable into an electrical signal necessary. The costs are therefore considerable and are used in price-critical applications in the household and / or consumer sector opposite.
Der Erfindung liegt die Aufgabe zugrunde, die Anordnung der Sensoren zu vereinfachen.Of the Invention is based on the object, the arrangement of the sensors to simplify.
Diese Aufgabe wird bei einem gattungsgemäßen Sensor durch die kennzeichnenden Merkmale des Anspruchs 1 gelöst.These Task is in a generic sensor by the characterizing Characteristics of claim 1 solved.
Beim erfindungsgemäßen Sensor sind die beiden elektrischen Wandlerelemente auf einem einzigen Träger befindlich. Weitere Ausgestaltungen der Erfindung sind Gegenstand der Unteransprüche.At the inventive sensor are the two electrical transducer elements on a single carrier located. Further embodiments of the invention are the subject the dependent claims.
In zweckmäßiger Ausgestaltung besitzt der Sensor ein Gehäuse, wobei die Meßkomponenten in dem Gehäuse angeordnet sind. Der Einfachheit halber bietet es sich an, daß der Träger mit einem einzigen Steckanschluß kontaktierbar ist, derart daß die zu den Meßgrößen korrespondierenden elektrischen Signale der elektrischen Wandlerelemente am Steckanschluß abgreifbar sind. Im Hinblick auf eine preiswerte Herstellung kann der Träger aus einer Leiterplatte, einem mit Kunststoff umspritzten Stanzgitter aus elektrisch leitfähigem Metall o. dgl. bestehen. Der Träger kann in Steckrichtung des Steckanschlusses ins Gehäuse eingesteckt sein, derart daß dabei alle Meßkomponenten in ihrer Solllage positioniert und/oder verrastet sind, womit eine einfache Montierbarkeit des Sensors gegeben ist.In expedient embodiment the sensor has a housing, wherein the measuring components in the case are arranged. For simplicity, it is advisable that the carrier with contacted a single plug connection is, so that the corresponding to the measured variables electrical signals of the electrical transducer elements can be tapped at the plug connection are. With regard to an inexpensive production, the carrier can be made a circuit board, a plastic-encapsulated stamped grid electrically conductive Metal o. The like. Exist. The carrier can be plugged into the housing in the plug-in direction of the plug connection be such that there all measuring components are positioned in their desired position and / or locked, bringing a simple mountability of the sensor is given.
Zusammenfassend ist für eine besonders bevorzugte Ausgestaltung festzustellen, daß die Komponenten der verschiedenen Meßfunktionen in einem Gehäuse derart angeordnet sind, daß die elektrischen Wandlerelemente sich alle auf einem einzigen Träger befinden, der seinerseits mit einem einzigen Steckanschluß kontaktierbar ist. Für eine preiswerte Herstellung werden die Wandlerelemente auf einem einzigen Träger, bevorzugt eine Leiterplatte oder ein umspritztes Stanzgitter, angeordnet, welcher in Steckrichtung des Steckanschlusses ins Gehäuse eingesteckt wird und dabei alle Sensoren in ihrer Solllage positioniert.In summary is for to determine a particularly preferred embodiment that the components the different measuring functions in a housing are arranged such that the electrical transducer elements are all on a single carrier, which in turn is contactable with a single plug connection. For a cheap Manufacture the transducer elements on a single carrier, preferably a printed circuit board or an overmolded stamped grid, arranged, which is plugged into the housing in the insertion direction of the plug connection is positioned while all sensors in their desired position.
Beispielsweise werden in einem Durchflußsensor, der nach bekannten Arbeitsprinzipen aus einem Gehäuse, einem von der durchströmenden Flüssigkeit angetriebenem Flügel- oder Turbinenrad, einem davon mitgenommenem Drehgeber und einem gehäusefest angeordneten Impulsgeber besteht, zusätzlich ein in den Flüssigkeitsstrom ragender Wärmeleiter, in dem ein Temperaturgeber sitzt, und die optoelektronischen Teile eines Trübungssensors an einem optisch durchlässigen Teil des vom Fluidstrom durchströmten Gehäuses angeordnet und die elektrischen Anschlüsse alle zu einen einzigen Steckanschluß geführt. Der Träger für die Bauteile läßt sich preiswert als ebene Leiterplatte ausgestalten, die im Gehäuse gegen Anschläge positioniert und verrastet ist. Für größere Stückzahlen kann jedoch auch ein umspritztes Stanzgitter als Träger verwendet werden, was kostenmäßige und konstruktive Vorteile hat. Eine Steck- und/oder Verrastrichtung des Trägers in der späteren Steckrichtung des Anschlusses kann die mechanische Festigkeit erhöhen.For example are in a flow sensor, the well-known working principles of a housing, a from the liquid flowing through powered wing or turbine wheel, one of them taken encoder and a fixed to the housing arranged pulse generator, additionally in the liquid flow protruding heat conductor, in which a temperature sensor sits, and the optoelectronic parts a turbidity sensor on an optically transparent Part of the flow through the fluid housing arranged and the electrical connections all led to a single plug connection. Of the carrier for the Components can be inexpensive designed as a flat circuit board, in the housing against attacks is positioned and locked. For larger numbers, however, can also overmoulded punched grid as carrier be used what cost and has constructive advantages. A plug-in and / or Verreastrichtung the carrier in the later Connecting direction of the connection can increase the mechanical strength.
Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß für Anwendungen, bei denen an fließenden Fluiden der Durchfluß, die Temperatur und/oder die Schmutzbelastung zu überwachen sind, alle Meßgrößen mit nur einem einzigen preisgünstig herzustellenden Kombisensor erfaßt und an einem einzigen Steckanschluß abgreifbar sind. Der vorgeschlagene Aufbau des Multisensors behebt damit die obengenannten Nachteile.The particular advantages of the invention are that for applications, at those at fluent Fluids of the flow, To monitor the temperature and / or the pollution load, all measured variables with only a single low priced detected combisensor detected and can be tapped at a single plug connection. The proposed structure of the multi-sensor thus eliminates the above Disadvantage.
