Description
Registriergeräte mit einer Vielzahl von quer zur trode an, deren Lage der Größe des durch die Stel-Bewegungsrichtung des Aufzeichnungsträgers in len/i bism dargestellten Meßwertes entspricht. Die gleichmäßigem Abstand voneinander angeordneten niederwertigen Stellen m-1 bis 0 des Meßwertes wer-Schreibelektroden sind bekannt. Entsprechend der 35 den am Umsetzer 3 in einen Analogwert umgesetzt Größe des Meßwertes wird jeweils eine Elektrode und dem Verschiebeantrieb 4 zugeführt, der den Träangesteuert, d.h., an eine elektrische Spannung ge- ger<5 der Meßelektroden proportional dem Analoglegt, die auf dem Aufzeichnungsträger eine Spur hin- wert, maximal um den Abstand zweier Elektroden terläßt. Als Aufzeichnungsträger wird z. B. ein ehe- verschiebt. Liegt beispielsweise der Meßwert 20,6 an. misch besonders präpariertes Papier verwendet 40 so wird die dem Wert 20 entsprechende Elektrode an-(USA.-Patentschrift *2 927 834). Bei einem anderen gesteuert und der Elektrodenträger um 60 0O des Abbekannten Verfallen wird ein elektrisches Ladungs- star.Urs zwischen zwei Elektroden zu höheren Werbild auf dem Träger erzeugt oder verändert und die ten hin verschoben. Als Verschiebeantrieb kann ein Aufzeichnung mittels eines Entwicklungsverfahrens bekannter elektromagnetischer Antrieb verwendet sichtbar gemacht (USA.-Patentschrift 3 394 385). Es 45 werden oder ein piezoelektrischer Antrieb, wie er können auch Aufzeichnungsträger mit einer Schicht schematisch in der Figur angedeutet ist. Hier wird an aus Flüssigkristallen verwendet werden. Die Auf- einen Biegestreifen 4 aus piezoelektrischem Material zeichnung ist infolge der Abstände der Aufzeich- eine der Verschiebebewegung entsprechende elektrinungselektroden und der damit verbundenen sprang- sehe Spannung angelegt. Der Streifen nimmt bei mahaften Änderung der Meßgröße nicht kontinuierlich 50 ximaler Verschiebung die gestrichelt gezeichnete und läßt ein stufenförmiges Bild erkennen. Lage ein.Recording devices with a large number of transversely to the electrode, the position of which corresponds to the size of the measured value represented by the direction of movement of the recording medium in len / i to m. The evenly spaced low-order points m-1 to 0 of the measured value wer-write electrodes are known. Corresponding to the size of the measured value converted into an analog value at the converter 3, one electrode is fed to the displacement drive 4, which controls the carrier, ie, to an electrical voltage of the measuring electrodes proportional to the analog value that is on the recording medium Leaves a trace worth a maximum of the distance between two electrodes. As a recording medium z. B. a marriage postponed. For example, if the measured value is 20.6. mixed specially prepared paper is used 40 so the electrode corresponding to the value 20 is used (USA. Patent * 2 927 834). In the case of another controlled and the electrode carrier decays by 60 0 O of the unknown, an electrical charge star.Urs is generated or changed between two electrodes to higher image on the carrier and the thes are shifted. As a displacement drive, a recording can be made visible by means of a development process known as an electromagnetic drive (US Pat. No. 3,394,385). There will be 45 or a piezoelectric drive, as it can also record carrier with a layer is indicated schematically in the figure. Here, an made of liquid crystals will be used. The drawing on a bending strip 4 made of piezoelectric material is applied as a result of the spacing between the recording and an electrical electrode corresponding to the displacement movement and the jump voltage associated therewith. In the event of a gradual change in the measured variable, the strip does not take the one drawn in broken lines continuously by 50 times the shift and reveals a stepped image. Location a.
