Aufgabe der Erfindung ist es, bei einen Miniaturmanometer der eingangs genannten Art die Anzeigegenauigkeit zu verbessern.task The invention is in a miniature pressure gauge of the aforementioned Way to improve the display accuracy.
Diese Aufgabe wird durch ein Miniaturmanometer mit den Merkmalen des Anspruchs 1 gelöst. Vorteilhafte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.These The object is achieved by a miniature pressure gauge with the features of the claim 1 solved. advantageous embodiments The invention are specified in the subclaims.
Bei dem erfindungsgemäßen Miniaturmanometer sind die beiden Schenkel des Verbindungsstücks derart flexibel ausgebildet, daß sie in jeder Stellung des Zeigers und damit im gesamten Meßbereich an dem Bourdonrohr anliegen. Sowohl in der besonders kritischen Mittelstellung als auch in den beiden Endstellungen ist somit kein Spiel zwischen den Schenkeln des Zeigers und dem zwischen ihnen gehaltenen Ende des Bourdonrohres vorhanden, wodurch die Anzeigegenauigkeit eines derartigen Miniaturmanometers innerhalb des gesamten Anzeigebereichs entscheidend verbessert werden kann.at the miniature gauge according to the invention the two legs of the connecting piece are designed to be so flexible, that she in every position of the pointer and thus in the entire measuring range abut the Bourdon tube. Both in the most critical Middle position as well as in the two end positions is thus no Play between the thighs of the pointer and the one held between them End of the Bourdon tube exists, reducing the display accuracy such a miniature manometer within the entire display area can be decisively improved.
In einer fertigungstechnisch besonders zweckmäßigen Ausführung der Erfindung bestehen die beiden Schenkel aus Kunststoff und sind einstöckig mit dem Zeiger ausgeführt. Der Zeiger kann zusammen mit den Schenkeln z.B. als Spritzgußteil aus einem Thermoplast auf Polyoxymethylen-Basis (POM) hergestellt sein.In a manufacturing technology particularly expedient embodiment of the invention are the two legs made of plastic and are executed in one piece with the pointer. Of the Pointer can be used together with the thighs e.g. as an injection molded part of a Polyoxymethylene-based (POM) thermoplastic.
