Abstract

Das Verfahren der Druckmessung unterscheidet sich dadurch, daß als elastisches Element das selbstzentrierte System verwenden. Das selbstzentrierte System unterhält die medialen und äußerlichen Rahmen 1, 2. Auf jedem Rahmen sind die Rollen 4 Rotationen gefestigt. Die Zahl der Rollen der Rotation auf jedem Rahmen ist nicht weniger drei identisch. Die Rollen der Rotation sind untereinander vom flexiblen Seil 3, dem Riemen oder der Kette serienweise verbunden. Die Wendung einen der Rollen zieht die Wendung aller übrigen Rollen. In den Abrieß des Seiles, des Riemens oder der Kette kann die Feder 6 für die Spannung aufgenommen sein. In der Ausgangsstellung besetzen die äußerlichen und medialen Rahmen verhältnismäßig einander mit der streng bestimmten Lage immer. Wenn zwischen dem medialen und äußerlichen Rahmen handeln die äußerlichen Kräfte, so verschieben sich die Rahmen verhältnismäßig einander. Wenn fehlen die äußerlichen Kräfte, so kehrt die relative Lage der Rahmen in die Ausgangsstellung zurück. Diese Ausgangsstellung hängt von der Größe der Kraft der Spannung des flexiblen Seiles nicht ab. Es bedeutet, dass hat das ganze System die Deformationsreste nicht. Als Umwandler der relativen Absetzung der Rahmen kann jede Art des Umwandlers, zum Beispiel, kapazitiv, magnetisch, optisch, resonanz-, tensometrisch, mechanisch verwendet sein.The pressure measurement method differs in that the self-centered system is used as the elastic element. The self-centered system maintains the medial and external frames 1, 2. The rollers 4 rotations are fixed on each frame. The number of rolls of rotation on each frame is identical not less than three. The rollers of the rotation are connected to each other in series by the flexible rope 3, the belt or the chain. The turn of one of the roles pulls the turn of all other roles. The spring 6 can be included for the tension in the tear off of the rope, belt or chain. In the initial position external and medial frames always occupy each other with strictly determined position. If the external forces act between the medial and external framework, the frameworks shift relative to one another. If the external forces are missing, the relative position of the frame returns to the starting position. This starting position does not depend on the magnitude of the force of tension in the flexible rope. It means that the whole system does not have residual deformation. Any type of converter, for example capacitive, magnetic, optical, resonance, tensometric, mechanical, can be used as the converter of the relative offset of the frames.

Description

Es sind die Verfahren der Druckmessung mit Hilfe der elastischen deformierten Elemente bekannt. Zum Beispiel, der Bourdonröhren, der Rohrmembräne, der flexiblen Diaphragma. Der Mangel dieser Verfahren ist das Deformationsrest der elastischen Elemente. ( DE000010154554A1 ), ( DE000010312467A1 )The methods of pressure measurement using the elastically deformed elements are known. For example, Bourdon's tubes, tubular membranes, flexible diaphragms. The defect of these methods is the deformation residue of the elastic elements. ( DE000010154554A1 ) DE000010312467A1 )

Ein Ziel der Erfindung ist die Nutzung des elastischen Elementes, das das Deformationsrest nicht hat.An object of the invention is the use of the elastic element that does not have the deformation residue.

Das gesetzte Ziel wird davon erreicht, daß als elastisches Element das selbstzentrierte System verwenden. Das selbstzentrierte System unterhält die medialen und äußerlichen Rahmen. Auf jedem Rahmen sind die Rollen der Rotation gefestigt. Die Zahl der Rollen der Rotation auf jedem Rahmen ist nicht weniger drei identisch. Die Rollen der Rotation sind untereinander vom flexiblen Seil, dem Riemen oder der Kette serienweise verbunden. Die Wendung einen der Rollen zieht die Wendung aller übrigen Rollen. In den Abrieß des Seiles, des Riemens oder der Kette kann die Feder für die Spannung aufgenommen sein. In der Ausgangsstellung besetzen die äußerlichen und medialen Rahmen verhältnismäßig einander mit der streng bestimmten Lage immer. Wenn zwischen dem medialen und äußerlichen Rahmen handeln die äußerlichen Kräfte, so verschieben sich die Rahmen verhältnismäßig einander. Wenn fehlen die äußerlichen Kräfte, so kehrt die relative Lage der Rahmen in die Ausgangsstellung zurück. Diese Ausgangsstellung hängt von der Größe der Kraft der Spannung des flexiblen Seiles nicht ab. Es bedeutet, dass hat das ganze System die Deformationsreste nicht. Als Umwandler der relativen Absetzung der Rahmen kann jede Art des Umwandlers, zum Beispiel, kapazitiv, magnetisch, optisch, resonanz-, tensometrisch, mechanisch verwendet sein.The set goal is achieved by using the self-centering system as the elastic element. The self-centered system maintains the medial and external frames. On each frame, the roles of rotation are consolidated. The number of roles of rotation on each frame is not less three identical. The roles of rotation are connected to each other in series by the flexible rope, the belt or the chain. The turn one of the rolls pulls the turn of all remaining rolls. The spring for the tension can be received in the thread of the rope, the belt or the chain. In the initial position external and internal frames always relatively occupy each other with strictly defined position. If external forces act between a medial and external framework, frames relatively shift each other. If the external forces are missing, the relative position of the frames returns to the starting position. This starting position does not depend on the magnitude of the force of the tension of the flexible cable. It means that the whole system does not have the deformation remainders. As a converter of the relative displacement of the frames, any type of converter may be used, for example, capacitive, magnetic, optical, resonance, tensometric, mechanical.

Im Beispiel der konkreten Erfüllung des Verfahrens ist die Konstruktion des Differenzdrucksensors aufgeführt.In the example of concrete performance of the method, the construction of the differential pressure sensor is listed.

Der Drucksensor unterhält den medialen Rahmen 1 und den äußerlichen Rahmen 2. Auf den Rahmen sind die Rollen 4 mit der Möglichkeit der Rotation bezüglich der Achsen 5 gefestigt. Alle Rollen sind untereinander vom elastischen Riemen 3 serienweise verbunden. In die Abrieße des Riemens sind die Feder 6 und den piezoresistiven Umwandler 7 aufgenommen. Auf dem äußerlichen Rahmen sind zwei Stutzbüchsen R1, R2 für die Verbindung mit den Quellen des gemessenen Druckes gefestigt. Die teilenden Membranen M1 und M2 wirken den medialen Rahmen 1 mit Hilfe der Stocke S1 und S2 ein. Bei der Abwesenheit oder bei der Gleichheit der Drücke in den Stutzbüchsen, besetzen die Rahmen mit der Ausgangsstellung verhältnismäßig einander.The pressure sensor maintains the medial frame 1 and the external frame 2 , On the frame are the rollers 4 with the possibility of rotation with respect to the axes 5 strengthened. All rollers are mutually elastic belt 3 connected in series. In the Abrieße of the belt are the spring 6 and the piezoresistive transducer 7 added. On the external frame are fixed two bushes R1, R2 for connection with the sources of the measured pressure. The dividing membranes M1 and M2 act on the medial frame 1 with the help of sticks S1 and S2. In the absence or equality of the pressures in the socket boxes, the frames with the initial position occupy each other relatively.

Auf der 1 ist der Differenzdrucksensor vorgestellt.On the 1 the differential pressure sensor is presented.

Auf der 2 ist die geänderte Lage des Differenzdrucksensors vorgestellt.On the 2 is presented the changed position of the differential pressure sensor.

Auf der 3 ist der Schnitt des Differenzdrucksensors vorgestellt.On the 3 is presented the section of the differential pressure sensor.
