Abstract
Temperaturfühler für integrierende Temperaturerfassung mit einem elektrischen Messanschluss (5) sowie einem Thermoelement welches zwei Thermoschenkel (1, 2) und eine Messstelle aufweist, dadurch gekennzeichnet, dass der Messanschluss (5) mittels der beiden Thermoschenkel (1, 2) mit einer Schweißstelle (4.2) verbunden ist und einer der beiden Thermoschenkel (2) eine weitere Schweißstelle (4.1) aufweist, wobei die Schweißstellen 4.1 und 4.2 durch einen Leiter aus dem Material des anderen Thermoschenkels (1) verbunden sind.Temperature sensor for integrating temperature measurement with an electrical measuring connection (5) and a thermocouple which has two thermal legs (1, 2) and a measuring point, characterized in that the measuring connection (5) by means of the two thermal legs (1, 2) with a welding point (4.2 ) and one of the two thermal legs (2) has a further welding point (4.1), the welding points 4.1 and 4.2 being connected by a conductor made of the material of the other thermal leg (1).
Description
Die Erfindung betrifft einen Temperaturfühler für integrierende Temperaturerfassung mit einem elektrischen Messanschluss sowie einem Thermoelement, welches zwei Thermoschenkel und eine Messstelle aufweist. The invention relates to a temperature sensor for integrating temperature detection with an electrical measuring connection and a thermocouple, which has two thermo legs and a measuring point.
Bekannt sind Widerstandsthermometer mit gestrecktem Messdraht, wie beispielsweise Nutenthermometer. Eine integrierende Wirkung wird mittels gestreckter oder teilweise gewickelter Messdrahtlänge erreicht. Nachteilig sind hierbei das aufwändige Herstellungsverfahren und eine geringe Zuverlässigkeit im Hochtemperaturbereich. Resistance thermometers with a stretched measuring wire, such as groove thermometers, are known. An integrating effect is achieved by means of stretched or partially wound measuring wire length. Disadvantages here are the complicated production process and low reliability in the high-temperature range.
Es ist weiterhin bekannt, Mittelwerte aus nebeneinander angeordneten Einzelmesskreisen oder Einzelmessfühler, wie z.B. bei Stufenthermoelementen zu bilden. Nachteilig ist hierbei die elektrische Auswertung, die für jeden Messkreis separat vorhanden sein muss. It is also known to use averages of juxtaposed single measurement circuits or single sensors, such as, e.g. to form at stage thermocouples. The disadvantage here is the electrical evaluation, which must be available separately for each measuring circuit.
Der Erfindung liegt die Aufgabe zugrunde, einen Temperaturfühler der eingangs genannten Art zu schaffen, der eine integrierte Messung und eine einfache Auswertung ermöglicht. The invention has for its object to provide a temperature sensor of the type mentioned, which allows an integrated measurement and a simple evaluation.
Erfindungsgemäß wird die Aufgabe mit einem Temperaturfühler gelöst, welcher die in Anspruch 1 angegebenen Merkmale aufweist. According to the invention the object is achieved with a temperature sensor, which has the features specified in
Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche. Advantageous embodiments are the subject of the dependent claims.
Der Temperaturfühler zeichnet sich dadurch aus, dass einer der beiden Thermoschenkel an zwei Stellen eine Schweißperle aufweist, welche zwei Messstellen bilden, wobei die beiden Messstellen mit einem Leiter aus dem Material des anderen Thermoschenkels elektrisch verbunden sind. The temperature sensor is characterized in that one of the two thermo legs has a weld bead in two places, which form two measuring points, wherein the two measuring points are electrically connected to a conductor made of the material of the other thermo leg.
Im sensitiven Teil des Thermoelementes wird damit eine Überbrückung hergestellt, wobei diese keinen Kurzschluss der Messspitze darstellt. In the sensitive part of the thermocouple a bridging is thus produced, which does not represent a short circuit of the measuring tip.
Als Material für die Thermoschenkel wird vorzugsweise Kupfer und eine Kupfer-Nickel-Legierung verwendet. As the material for the thermo legs copper and a copper-nickel alloy is preferably used.
Ausführungsbeispiele der Erfindung werden im Folgenden anhand von Zeichnungen näher erläutert. Embodiments of the invention are explained in more detail below with reference to drawings.
