Description

Druckmesser mit Signallampe. Gegenstand der Erfindung ist ein Druckanzeiger mit elektrischer Signallampe von besonders einfacher und billiger Ausführung, der nur (las Vorhandensein eines Mindestdruckes anzeigt. Der Druckanzeiger ist mit einem an sich bekannten Signalknopf verbunden. Die Erfindung besteht in der Ergänzung dieser Einrichtung durch eine Signallampe.Pressure gauge with signal lamp. The invention relates to a pressure indicator with an electric signal lamp of a particularly simple and cheap design, the only (reads the presence of a minimum pressure. The pressure indicator is with a known signal button connected. The invention consists in the supplement this facility by a signal lamp.

I#'alls der erforderliche Mindestdruck nicht vorhanden ist, leuchtet eine Lampe auf, welche im Innern des Druckanzeigers auswechselbar angeordnet ist. Die aufleuchtende Lampe sitzt hinter einer roten Scheibe, so daß im Augenblick der Gefahr ein rotes Signal aufleuchtet. Die Zeichnung zeigt in Abb. i die Vorrichtung ohne Druck im Schnitt im Aufriß, Abb. 2 den Grundriß der Vorrichtung, Abb. 3 die Vorrichtung im Schnitt von der Seite unter Druck.If the required minimum pressure is not available, a lamp lights up, which is arranged in an exchangeable manner inside the pressure indicator. The lamp that lights up is located behind a red pane, so that a red signal lights up at the moment of danger. The drawing shows in Fig. 1 the device without pressure in section in elevation, Fig. 2 shows the plan view of the device, Fig. 3 shows the device in section from the side under pressure.

Das Gehäuse a trägt einen Gewindedeckel b, welcher mit einem roten Fenster c versehen ist. In (lern Gewiu(le(leclzel c ist der eine Pol des Leuchtkörpers d angebracht, dessen anderer Pol e am Boden des Gehäuses befestigt ist und auf dem ein Kontaktf ruht, dessen Federg am Knopf h befestigt ist, der durch eine Feder i auf die Membran k gedrückt wird. Von dem Kontakt geht eine elektrische Leitung 1 ab. Befindet sich der Druckmesser nicht unter Druck, so liegt der Knopf mit der Membran flach auf dem Anschlußstutzen, und die beiden Kontaktfedern berühren sich, so daß ein Strom fließt, der die Lampe aufleuchten läßt. Ist ein genügender Druck vorhanden, so steigt der Knopf bis gegen das als Anschla.g nach innen gezogene Gehäuseteil; die eine Kontaktfeder steigt mit dem Knopf, an dem sie befestigt ist, empor, und dadurch wird der Strom unterbrochen. Die Signallampe erlischt. Sinkt der Druck unter den zulässigen 'Mindestdruck, so spielt sich derselbe Vorgang in umgekehrter Reihenfolge ab, das heißt der Knopf sinkt zurück, die beiden Kontaktfedern schließen den Stromkreis, und die Signallanipe leuchtet auf.The housing a carries a threaded cover b, which is provided with a red window c. In (lern Gewiu (le (leclzel c) one pole of the luminous element d is attached, the other pole e of which is attached to the bottom of the housing and on which a contact r rests, the spring of which is attached to the button h, which is attached to the membrane is pressed k. from the contact an electric line 1 does not come off. located at the pressure gauge pressure, the button is located with the membrane flat on the connection piece and the two contact springs touch, so that a current flows, the If there is sufficient pressure, the button rises up to the part of the housing that is pulled inwards as a stop; one contact spring rises up with the button to which it is attached, and the current is interrupted If the pressure falls below the permissible minimum pressure, the same process takes place in reverse order, i.e. the button sinks back, the two contact springs close the circuit and the Si gnallanipe lights up.

PATENTANSPRUCH -. Druckmesser mit Signallampe, dadurch gekennzeichnet, daß ein Signalki-topf (h). el auf den einerseits die vom Druckmitt beeinflußte Membran (le), andererseits eine Gegenfeder (i) wirkt. ein Kontaktstück (f) trägt, das den Stromkreis der Signallampe (d) nur bei der dem 'Xfindestdruck entsprechenden tiefsten Stellung der Membran schließt. PATENT CLAIM -. Pressure gauge with signal lamp, characterized in that a signal plug (h). el on the one hand the diaphragm (le) influenced by the pressure medium and on the other hand a counter spring (i) acts. carries a contact piece (f) which closes the circuit of the signal lamp (d) only when the membrane is in the lowest position corresponding to the test pressure.
