Description

Anordnung zur Einstellung des Sollwertes bei Reglern mit elektrischem Reglermeßwerk und hierzu in Reihe geschaltetem Anzeigegerät Die. Neuerung bezieht sich auf eine Anordnung zur Einstellung des Sollwertes bei Reglern mit in den meisten Fällen noch vorhandenen Registrier-oder Anzeigegeräten. Bei diesen Reglern kann die den Sollwert abbildende Spannung dem Meßwert nicht unmittelbar elektrisch überlagert werden da hierbei der Ausschlag bei nicht abgeglichener Reglerbrücke gefälscht wird.Arrangement for setting the setpoint for controllers with electrical controller measuring mechanism and connected in series for this purpose Display device The. The innovation relates to an arrangement for setting the setpoint value in regulators with recording or display devices that are still present in most cases. With these controllers, the voltage representing the setpoint cannot be electrically superimposed on the measured value, since the deflection is falsified if the controller bridge is not adjusted.

Durch die Erfindung wird die Sollwertaufschaltung auf das Meßwerk ohne Beeinflussung des Anzeige-oder Registriergerätes möglich* Meßwerk, deren bewegliches System mehrere Spulen trägt, sind an sich bekannt. Bei Meßwerken für Regelzwecke hat man bereits neben der Meßspule auf dem beweglichen System eine zweite Spule angebracht, an die eine dem Ruckfuhrwert proportionale Spannung angeschlossen. ist.The invention enables the setpoint value to be applied to the measuring mechanism without influencing the display or recording device possible* Measuring mechanism, the moving system of which carries several coils, are known per se. With measuring units for control purposes one already has In addition to the measuring coil, a second coil is attached to the movable system, to which a voltage proportional to the return value is connected. is.

Es ist bekannt, die zweite Spule mit einer entsprechend dem Sollwert des Reglers einstellbaren Spannung zu speisen.It is known that the second coil with a corresponding to the setpoint the adjustable voltage of the controller.

Hierbei ist jedoch die Meßspule mit einem Widerstandsthermometer in Reihe geschaltet und beide Spulen werden von der gleichen Spannungsquelle gespeist. In dieser Schaltung kann die Meßspannung nicht den Wert Null durchlaufen. Da beide Spulen über einen gemeinsamen Vorwiderstand gespeist werden, ist ausserdem die Meßspannung vom eingestellten Sollwert abhängig und dieser kann daher nur innerhalb bestimmter Grenzen verändert werden, da sonst zu große Messfehler auftreten.Here, however, the measuring coil with a resistance thermometer is in Connected in series and both coils are fed by the same voltage source. In this circuit, the measuring voltage cannot pass through the value zero. Since both Coils are fed via a common series resistor, is also the measuring voltage depends on the set target value and can therefore only be used within certain Limits are changed, otherwise measurement errors that are too large will occur.

Bei einer Anordnung zur Einstellung des Sollwertes bei Reglern mit einem elektrischen Reglermesswerk, das zwei bewegliche . Spulen besitzt und wobei die den Meßwert erfassende Spule in der Messdiagonalen einer Brückenschaltung liegt, wird daher gemäß der Neuerung die zweite Spule aus einer von der Meßspannungsquelle unabhängigen Spannungsquelle gespeist und der an der Spule liegende Spannungswert ist entsprechend dem Sollwert des Reglers einstellbar. Infolge der Brückenschaltung kann der Mesawert den Wert Null durchlaufen und da eine getrennte Spannungsquelle zur Einstellung des Sollwertes benutzt ist. Sparmungso wird der Messwert von der Sollwerteinstellung nicht beeinflußt.In an arrangement for setting the setpoint in controllers with an electrical controller measuring mechanism, the two movable ones. Has coils and where the coil which detects the measured value lies in the measuring diagonal of a bridge circuit, according to the innovation, the second coil is therefore fed from a voltage source independent of the measured voltage source and the voltage value across the coil can be adjusted according to the setpoint of the controller. As a result of the bridge circuit, the mesa value can pass through the value zero and there a separate one Voltage source is used to set the setpoint. Savings so the measured value is not influenced by the setpoint setting.

Die beiden Spulen können auf dem gleichen Meßwerkrähmchen sitzen und einpolig miteinander verbunden werden, so daß nur drei Zuführungen zum beweglichen System notwendig sind. Es kann ein normales Meßwerk verwendet werden. Der Wickelraum des Rähmchens wird dann z. B ß0 aufgeteilte daß die Meßspule 90 % und die Sollwertspule 10 % des gesamten zur Verfügung stehenden Wickelraumes einnimmt. Die. Empfindlichkeit des Meßwerks wird hierdurch niehtnennenswsrt beeinflußt. Der den Sollwert abbilkdenden elektischen Spannung kann außerdem der Rückführwert des Reglers als elektrische Spannung überlagert werden. Beide Spannungen werden dann gemeinsam auf die zweite Spule geschaltet. Die Zeichnung zeigt gemäss der Neuerung aufgebaute Schaltungen zur Sollwerteinstellung. In der Fig. 1 sdl z. B. 1 eine Brückenschaltung eines CO2- oder Sauerstoffmessers darstellen.The two coils can sit on the same measuring frame and be connected to one another with one pole, so that only three leads to the moving system are necessary. A normal measuring mechanism can be used. The changing room of the frame is then z. B ß0 divided that the measuring coil 90% and the Setpoint coil takes up 10% of the total available winding space. The. This does not affect the sensitivity of the measuring mechanism. The electrical voltage representing the setpoint can also be superimposed on the feedback value of the controller as electrical voltage. Both voltages are then switched to the second coil together. The drawing shows circuits for setpoint adjustment constructed according to the innovation. In Fig. 1 sdl z. B. 1 represent a bridge circuit of a CO2 or oxygen meter.

Die Messbrücke 2 und die Vergleichsdrähte 3 liegen in einer Brückenschaltung und die dem Messwert entsprechende Brückenspannung wird der Meßspule 4 des Reglermesswerkes und einem Anzeigegerät 5 zugeleitet. Die den Sollwert abbil-' dende Spannung wird an einem in einer Brückenschaltung liegenden Potentiometer 7 abgegriffen. Die Brückenschaltung ist durch die Schaltelemente 7 und den Punkt 8 nur andeutungsweise dargestellt. Der in dieser Brücke abgegriffenen Sollwertspannung ird mit der Schaltung 6 der Rückführwert des Reglers überlagert. Beide Spannungen werden gemeinsam der zweiten Spule 9 des Reglermesswerkes zugeführt. Fig. 2 zeigt die Bildung der Sollwertspannung mittels einer Batterie 10 und eines je nach dem gewünschten Sollwert einstellbaren Potentiometers 11.The measuring bridge 2 and the comparison wires 3 are in a bridge circuit and the bridge voltage corresponding to the measured value becomes the measuring coil 4 of the regulator measuring mechanism and fed to a display device 5. The voltage representing the setpoint is tapped at a potentiometer 7 located in a bridge circuit. The bridge circuit is only indicated by the switching elements 7 and the point 8. The setpoint voltage tapped in this bridge is connected to circuit 6 of Feedback value of the controller superimposed. Both tensions become the second together Coil 9 of the regulator measuring mechanism supplied. Fig. 2 shows the formation of the setpoint voltage by means of a battery 10 and one adjustable depending on the desired setpoint Potentiometer 11.
