Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Durch Messung von Druck und Temperatur eines strömenden Mediums wird meist eine dritte physikalische Größe bestimmt.By measuring the pressure and temperature of a flowing medium is usually a third physical quantity is determined.

Die bisher bekannte Anordnung besteht nun darin, daß man einen beliebigen Wärmemesser (Hg-Thermometer, Thermoelement oder elektrisches Widerstandsthermometer) an der betreffenden Meßstelle anordnet; gleichzeitig bringt man auch den erforderlichen AnschlußThe previously known arrangement now consists in using any heat meter (Mercury thermometer, thermocouple or electrical resistance thermometer) at the relevant measuring point; simultaneously you also bring the necessary connection

ίο eines beliebigen Druckmessers in kleinerer oder größerer Entfernung an oder macht das Anschlußrohr des Druckmessers zum Träger des Wärmemessers, je nachdem es die örtlichen Verhältnisse erlauben. Obwohl nun die Einzelmessungen von Druck und Temperatur, jede für sich genommen, als richtig anzunehmen sind, ist jedoch die daraus bestimmte dritte physikalische Größe mit größeren Fehlern behaftet, weil die Meßinstrumente nicht genau an demselben Ort sitzen, und bekanntlich sind Druck und Temperatur in einem strömenden Medium an jedem Ort veränderlich. Hierzu kommt noch der weitere Umstand, daß es an und für sich schwierig und oft geradezu unmöglich ist, zwei verschiedene Instrumente an einer bestimmten Stelle oder mindestens in unmittelbarer Nähe anzuschließen. Der Zweck der nachfolgenden Erfindung ist nun die Beseitigung vorstehender Mängel, wie in folgendem beispielsweise gezeigt wird.ίο any pressure gauge in a smaller one or greater distance or makes the connecting pipe of the pressure gauge to the carrier of the heat gauge, depending on it local conditions allow. Although now the individual measurements of pressure and temperature, each taken individually, can be assumed to be correct, however, is that third physical quantity determined therefrom is subject to greater errors because the measuring instruments not sitting in exactly the same place, and as is well known, pressure and temperature are changeable in a flowing medium at any place. In addition there is the further fact that it is an and for difficult and often downright impossible to use two different instruments on one at a certain point or at least in the immediate vicinity. The purpose The following invention is now the elimination of the foregoing deficiencies, as in the following for example is shown.

Ausgegangen werde z. B. von den bekannten Einrichtungen eines Thermoelementes, dessen zwei verschiedene Metalle in diesem Fall aber als Hülsen α und b (Fig. 1) ausgebildet sind und am Ende entweder auf einem Vollring oder Ringsektor c verlötet sind. Diese beiden Hülsen sind nun gleichzeitig die Anschlußrohre für ein oder zwei Manometer; dabei kann die Metallhülse α noch verschiedene Löcher d haben. Das Thermoelement selbst wird durch Anlegung der Schließungsdrähte an die Klemmen β und f vervollständigt. It is assumed z. B. of the known devices of a thermocouple, the two different metals in this case, however, are designed as sleeves α and b (Fig. 1) and are soldered at the end either on a full ring or ring sector c. These two sleeves are now at the same time the connection pipes for one or two pressure gauges; the metal sleeve α can also have different holes d . The thermocouple itself is completed by applying the closing wires to terminals β and f .

Fig. 2 zeigt dasselbe mit nebeneinander angeordneten Hülsen α und b. Fig. 2 shows the same with sleeves α and b arranged side by side.
