Die Erfindung bezieht sich auf Kontaktmanometer, die auf einen bestimmten Schaltdruck einstellbar sind und betrifft eine Ausgestaltung, bei der der Schaltkontakt durch einen Drehschalter auf mehrere vorbestimmte, an sich beliebige Druckwerte einstellbar ist.The invention relates to contact pressure gauges which can be adjusted to a specific switching pressure and relates to an embodiment in which the switching contact is set to several predetermined, any pressure values can be set.
Man kennt solche Kontaktmanometer mit einem verschwenkbaren Mikroschalter, dessen Schalthebel auf einer vom Druckmeßwerk mechanisch gesteuerten Kurvenscheibe gleitet. In einem anderen bekannten Kontaktmanometerwird eine Exzenterverstellung vorgeschlagen, mit der man die relative Stellung des Kontaktgebers gegenüber dem Impulsgeber verändern kann.One knows such contact pressure gauges with a pivotable microswitch, its switch lever slides on a cam mechanically controlled by the pressure measuring mechanism. In another well-known Contact manometer, an eccentric adjustment is proposed with which one can determine the relative position of the contactor can change compared to the pulse generator.
Die Erfindung besteht darin, daß die Kurvenscheibe mehrere Schaltabschnitte (schräge Kurven) aufweist, die durch Kreisbögen steigenden Durchmessers verbunden sind, und daß ein den Mikroschalter tragender Schwenkarm unter der Spannung einer Feder gegen eine Stufenscheibe anliegt, deren Schaltstufen den Schaltabschnitten der Kurvenscheibe zugeordnet und den Durchmessern der Kreisbogen entsprechend bemessen sind, so daß der Schalthebel in jedem Schaltabschnitt dieselbe Mittelstellung einnimmt. Dabei kann in Ausgestaltung der Erfindung mit der Stufenscheibe ein Zeiger verbunden werden, der auf einer Kreisskala die Schaltstellung erkennen läßt.The invention consists in that the cam has several switching sections (inclined curves), which are connected by arcs of increasing diameter, and that one carrying the microswitch Swivel arm rests against a stepped disk under the tension of a spring, the switching stages of which the Assigned switching sections of the cam and dimensioned according to the diameters of the circular arcs are, so that the shift lever assumes the same central position in each shift section. Included can in an embodiment of the invention with the stepped disk, a pointer can be connected to a Circular scale shows the switch position.
Durch diese Ausgestaltung kann man das Gerät durch Drehen der Stufenscheibe leicht auf den gewünschten Druckwert, den man auf der Skala ersehen kann, einstellen und verstellt dadurch den Schwenkarm mit dem Mikroschalter so, daß der Schalthebel in jedem Schaltabschnitt dieselbe Mittelstellung einnimmt. Dadurch wird es möglich, auf begrenztem Raum eine große Zahl von Schaltstellungen und dementsprechend von Druckwerten unterzubringen, wobei Fehlschaltungen sicher vermieden werden und jeder Schaltvorgang mit großer Präzision ausgeführt wird. Hierin liegt ein erheblicher Fortschritt der Erfindung gegenüber der bekannten Technik.With this configuration, the device can easily be adjusted to the desired position by turning the stepped disk Set the pressure value, which can be seen on the scale, and thereby adjusts the swivel arm with the microswitch in such a way that the switching lever assumes the same central position in each switching section. This makes it possible to have a large number of switching positions and accordingly in a limited space of pressure values, whereby incorrect switching is reliably avoided and every switching operation is carried out with great precision. Herein lies a considerable advance of the invention compared to the known technology.
