Description

KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Den Gegenstand der vorliegenden Erfindung bildet ein vereinfachter Druckmesser mit Wärmeausgleich nach Patent 224213.The subject of the present invention is a simplified pressure gauge Heat compensation according to patent 224213.

Nach dem älteren Patent 224213 ist zwisehen den vom Druck beeinflußten Körper und das Werk ein Kompensationsstück eingeschaltet, welches verhindert, daß das Manometer, wenn es durch den Dampf usw. erwärmt wird, einen höheren Druck anzeigt, als in Wirklichkeit vorhanden ist. Gemäß vorliegender Erfindung ist der Druckmesser nun dadurch vereinfacht, daß das druckempfindliche Organ (Röhren- oder Plattenfeder) selbst als Wärmedehnungsausgleicher ausgebildet ist, beispielsweise durch Auf- oder Einlötung eines Kompensationsstreifens von anderem Ausdehnungskoeffizienten auf dieses druckempfindliche Organ.According to the earlier patent 224213 there is a difference the body influenced by the pressure and the movement switched on a compensation piece, which prevents the pressure gauge, when heated by the steam, etc., from showing a higher pressure than actually exists. In accordance with the present invention, the pressure gauge is now simplified by the fact that the pressure-sensitive organ (tubular or plate spring) itself is designed as a thermal expansion compensator, for example by soldering or soldering a Compensation strip of different expansion coefficient on this pressure-sensitive Organ.

Auf der Zeichnung ist der Erfindungsgegenstand in einer beispielsweisen Ausführungsform an einem Röhrenfedermanometer veranschaulicht, und zwar istIn the drawing, the subject matter of the invention is illustrated in an exemplary embodiment on a tubular spring manometer, namely is

Fig. ι eine Vorderansicht, zum Teil im Schnitt, des gesamten Manometers,Fig. Ι a front view, partly in Section, of the entire manometer,

Fig. 2 eine Draufsicht auf den den Kornpensationsstreifen tragenden Teil der Röhrenfeder. Fig. 2 is a plan view of the compensation strip load-bearing part of the tubular spring.

Die Einrichtung des Manometers ist die übliche, braucht daher nicht näher beschrieben zu werden. Auf die Röhrenfeder α ist der Kompensationsstreifens h aus einem Material von anderem Ausdehnungskoeffizienten als die Röhrenfeder aufgelötet, so daß die durch die Erwärmung bewirkte Formänderung ausgeglichen wird.The setup of the manometer is the usual one and therefore does not need to be described in more detail. The compensation strip h made of a material with a different coefficient of expansion than the tubular spring is soldered onto the tubular spring α, so that the change in shape caused by the heating is compensated for.

Die Anwendung der Erfindung bei Plattenfedermanometern ist hiernach ohne weiteres klar.The application of the invention to diaphragm pressure gauges is then readily apparent.
