Description

Vorrichtung zur Umwandlung einer Druckschwankung. Device for converting a pressure fluctuation.

Die vorliegende Neuerung betrifft eine Vorrichtung zur Umwandlung einer Druckschwankung in eine elektrische Meßgröße. The present innovation relates to a device for conversion a pressure fluctuation into an electrical measured variable.

Die Vorrichtung ist in der Weise gestaltet, daß eine der zu messenden Druckschwankung unterworfene Membrane über einen Gelenkhebel mit einer Welle derart verbunden ist, daß die Welle eine Rotation um ihre Längsachse ausführt, wenn sich die Membrane unter der Wirkung der Druckschwankungen bewegt, wobei auf der Welle ein Magnet fest angeordnet ist, dessen Kraftlinien durch eine Trennwand des Vorrichtungsgel, äuses auf einen zweiten, außerhalb desselben angeordneten Magneten einwirken, der seinerseits einen elektrischen Widerstand, z.B. einen Potentiometer betätigt.The device is designed in such a way that one of the to be measured Diaphragm subjected to pressure fluctuations via an articulated lever with a shaft in this way is connected that the shaft performs a rotation about its longitudinal axis when the diaphragm moves under the action of the pressure fluctuations, being on the shaft a magnet is firmly arranged, the lines of force through a partition of the device gel, äuses act on a second, outside of the same arranged magnet, the in turn actuates an electrical resistor, e.g. a potentiometer.

In der Abbildung ist die Vorrichtung dargestellt, und zwar an zwei zueinander senkrechten Längsschnitten. In the figure the device is shown on two longitudinal sections perpendicular to each other.

Die zu messende Druckdifferenz wird zwischen den Stutzen St. 1 und St. 2 angelegte Unter dem Einfluß von Druckschwankungen wird die Membrane Mb. mehr oder weniger stark gedehnt oder zusammengezogen. Die Bewegung der Membrane wirkt über den Gelenkhebel G auf die Welle W ein, die in Spitzen gelagert ist. Je nach der Bewegung der Membrandeckels dreht sich die Welle W um ihre Längsachse in der einen oder anderen Richtung. Auf der Welle W ist ein Magnet M. l befestigt, dessen Kraftlinien zwischen den Polen durch die magnetisch durchlässige Trennwand T. des Gehäuses H. hindurchreichen und auf die entsprechenden Gegenpole eines außerhalb angeordneten Magneten M. 2 wirken. Sobald sich mit der Drehung der Welle W. der Magnet 1 dreht, wird auch der Magnet 2 mitgenommen und dreht beispielsweise den Schleifer eines Regelwiderstandes Wie Der Vorteile der Neuerung besteht darin daß eine große einstellbare Meßgenauigkeit erzielt wird. Außerdem ist das Gerät klein im Aufbau und stounospfindlich und kann stehend oder liegend eingebaut werden. The pressure difference to be measured is applied between the nozzles St. 1 and St. 2. Under the influence of pressure fluctuations, the membrane Mb. Is stretched or contracted to a greater or lesser extent. The movement of the membrane acts via the articulated lever G on the shaft W, which is mounted in points. Depending on the movement of the membrane cover, the shaft W rotates around its longitudinal axis in one direction or the other. A magnet M. l is attached to the shaft W, the lines of force of which extend between the poles through the magnetically permeable partition T. of the housing H. and act on the corresponding opposite poles of a magnet M. 2 arranged outside. As soon as the magnet 1 rotates with the rotation of the shaft W., the magnet 2 is also carried along and rotates, for example, the slider of a variable resistor. aside from that the device is small in structure and sensitive to shock and can be installed vertically or horizontally.
