Description
Für viele Betriebe, z. B. in Kesselhäusern bei der Rauohgiasanalyse, ist es erforderlich, aus einer Reihe von Messungen Mittelwerte zu ziehen, um daraus Schlüsse auf die Songfalt der Bedienung usw. ziehen zu können. Diese Notwendigkeit macht umständliche Rechnungen erforderlich.For many companies, e.g. B. in boiler houses in the Rauohgiasanalyse, it is necessary, to draw mean values from a series of measurements in order to draw conclusions about the variety of songs the operation, etc. to be able to pull. This necessity makes it cumbersome Invoices required.
Gegenstand der vorliegenden Erfindung ist nun eine Vorrichtung, um solche MittelwerteThe present invention now relates to a device for determining such mean values
ίο anzuzeigen und es dem Betriebspersonal zu ermöglichen, sie jederzeit ablesen zu können,. Um die Aufgabe zu lösen, wird eine Vorrichtung verwandt, in welcher der Kreuzungspunkt zweier sich schneidender Zeiger den zu messenden Wert anzeigt. Erfindungsgemäß ist diese Vorrichtung nun so gestaltet, daß innerhalb eines Koordinatensystems zwei sich schneidende Arme derart winkelgleich zueinander verstellt werden, daß der eine nach Maßgabe der von dem Meßinstrumente angezeigten Meßwerte, der andere nach Maßgabe bestimmter Zeitabschnitte bewegt wird zum Zwecke, den Mittelwert aus einer MehrzaM von Messungen desselben Instrumentes un-ίο to indicate and to the operating staff enable you to read them at any time. In order to solve the problem, a device used, in which the point of intersection of two intersecting pointers indicates the value to be measured. According to the invention this device is now designed so that two within a coordinate system cutting arms are adjusted at the same angle to each other that the one after According to the measured values displayed by the measuring instrument, the other according to the measure certain periods of time is moved for the purpose of finding the mean value from a MehrzaM of measurements of the same instrument and

Dieser allgemeine Lösungsgedanke kann zweckmäßig nach der vorliegenden Erfindung d'adurch verwirklicht werden, daß die Achsen mit je einer Buchse verbunden sind, welche auf winklig zueinander angeordneten Spindein in der Längsrichtung der letzteren verstellbar gelagert sind.This general idea of the solution can be expedient according to the present invention d'be realized by the axes are each connected to a socket, which on angled to each other spindles are mounted adjustably in the longitudinal direction of the latter.
Besonders einfach gestaltet sich die Vorrichtung erfindiungsgemäß dadurch, daß die Spindeln durch elektromagnetische Schritt-Schaltwerke bewegt werden, von denen das eine von einem in bestimmten Zeitabschnitten betätigten Kontaktwerk und das andere von einer die Meßwerte anzeigenden Einrichtung gesteuert wird.The device is particularly simple according to the invention in that the Spindles are moved by electromagnetic stepping mechanisms, one of which is the one by a contact mechanism operated in certain time periods and the other by a device displaying the measured values is controlled.
In Abb. ι ist ein Ausführungsibeispiel und in Abb. 2 die elektromagnetische Fortschaltung der Spindeln schematiseih dargestellt.In Fig. Ι is an exemplary embodiment and in Fig. 2 the electromagnetic switching of the spindles is shown schematically.
α und b sind zwei Achsen, z. B. Stäbe, welche au den Trägern c und d befestigt sind. A und B sind zwei Spindeln, auf denen die Träger c und d bei Drehung der Spindeln derart entlanggleiten, daß die' Achsen α und & winkelgleicih zueinander verstellt werden. Beide Spindeln A und B veranschaulichen das α and b are two axes, e.g. B. rods which are attached to the beams c and d. A and B are two spindles on which the supports c and d slide along when the spindles are rotated in such a way that the axes α and are adjusted at the same angle to one another. Both spindles A and B illustrate this

Koordinatensystem, innerhalb welchem die Arme α und b winkelgleich verstellt werden. Die Spindel B wird nun in bestimmten gleichmäßigen Zeitabständen um je einen bestimmten Winkel gedreht, so daß der Träger d innerhalb derselben Zeitabschnitte um je ein bestimmtes Stück in der Richtung des Pfeiles weitergerückt wird. Die Spindel A dagegen wird entsprechend den MeßwertenCoordinate system within which the arms α and b are adjusted at the same angle. The spindle B is now rotated at certain regular intervals of time by a certain angle so that the carrier d is advanced within the same time segments by a certain distance in the direction of the arrow. The spindle A, on the other hand, is adjusted according to the measured values
ίο innerhalb eines Zeitabschnittes mehrmals um denselben Winkel gedreht. Wird z. B. in dem Zeitabschnitt t die Spindel B einmal gedreht und ist in derselben Zeit der Meßwert n, so wird die Spindel A in dem Zeitraum t n-mal um den gleichen Winkel gedreht. Dementsprecehnd macht die Achse α η - gleiche Schritte und die Achse b einen Schritt in der angedeuteten bezüglichen Pfeilrichtung. Auf diese Weise werden die beiden Achsen αίο rotated several times by the same angle within a period of time. Is z. B. in the time segment t the spindle B is rotated once and the measured value n is at the same time, the spindle A is rotated n times by the same angle in the period t. Accordingly, the axis α η makes the same steps and the axis b one step in the indicated relative arrow direction. In this way the two axes become α
und δ winkelgleich im Verhältnis ^ψγ- zueinander verstellt. Der Kreuzungspunkt P beider Achsen zeigt dann, über eine strahlenförmige Skala geführt, den jeweiligen Mittelas wert der ausgeführten Messungen an. Die Skala ist dabei erfindungsgemäß entsprechend verschiedener A^erhältniswerte aus der Summe der Meßwerte innerhalb eines bestimmten Zeitraumes und dieses Zeitraumes geeicht. Der Antrieb der Spindel A und B kann in einfachster Weise dadurch geschehen, daß die Fortbewegung mit Hilfe eines elektromagnetischen Schrittschaltwerkes erfolgt, dessen Arbeitsweise in Abb. 2 schematisch dargestellt ist. S1 (S2) ist ein auf der Spindel A bzw. B befestigtes Zahnrad, in welches eine Stoßklinke K eingreift. Diese Klinke ist mit dem Anker des Bewegungselektromagneten D beweglich verbunden, so daß bei jedesmaliger Stromschließung über den Schaltelektromagneten D das Rad S1 bzw. S2 um einen Schritt gedreht wird, wodurch die Achsenträger c und c? entsprechend schrittweise fortbewegt werden. Der Stromkreis für den Fortschaltmagneten der Spindel A wird: über ein von dem Meßinstrument betätigtes Kontaktwerk innerhalb eines bestimmten Zeitabschnittes mehrmals, entsprechend den jeweiligen Meßwerten, geschlossen. Der Stromkreis für den Antriebsmagneten der Zeitspindel B dagegen wird von einem Kontaktwerk geschlossen, welches durch eine Uhr in bestimmten Zeitabschnitten betätigt werden kann. Selbst- I verständlich können die Kontaktwerke für Meßwerte und Zeit auch an dem Meßinstru- : ment vereinigt sein. Der Mittelungsanzeiger ] selbst kann an einem beliebig entfernten Ort !and δ adjusted at the same angle in the ratio ^ ψγ- to each other. The intersection point P of both axes then shows the respective mean of the measurements carried out, guided over a radial scale. According to the invention, the scale is calibrated according to different ratio values from the sum of the measured values within a certain period and this period. The drive of the spindles A and B can be done in the simplest way that the locomotion takes place with the aid of an electromagnetic stepping mechanism, the mode of operation of which is shown schematically in Fig. 2. S 1 (S 2 ) is a gear attached to the spindle A or B , in which a pawl K engages. This pawl is movably connected to the armature of the movement electromagnet D , so that each time the current is closed via the switching electromagnet D, the wheel S 1 or S 2 is rotated by one step, whereby the axle carriers c and c? be moved step by step accordingly. The circuit for the indexing magnet of the spindle A is closed several times within a certain period of time, according to the respective measured values, via a contact mechanism actuated by the measuring instrument. The circuit for the drive magnet of the time spindle B, on the other hand, is closed by a contact mechanism which can be operated by a clock in certain time segments. I self-evident the contact works for measured values and time can also join the Meßinstru-: be unified management. The averaging indicator] itself can be at any remote location!
aufgestellt werden, was sich als ein besonderer Vorzug der Anwendung der elektrischen Fortschaltung darstellt.what turns out to be a particular advantage of the application of the electrical Represents progression.
Sobald ein Träger c oder d das Ende der Spindel erreicht, ist die Stillsetzung des Apparates erforderlich, was in einfachster Weise dadurch erfolgen kann, daß der Träger c bzw. d einen Kontakt 0 bzw. p betätigt, welche im Stromkreis der Bewegungselektromagneten, wie in Abb. 2 angedeutet, liegen. Die Rückführung der Träger in die Anfangslage kann dann von Hand in beliebiger Weise er-, folgen.As soon as a carrier c or d reaches the end of the spindle, it is necessary to shut down the apparatus, which can be done in the simplest way that the carrier c or d actuates a contact 0 or p , which is in the circuit of the motion electromagnet, as in Fig. 2 indicated, lie. The carrier can then be returned to the initial position by hand in any desired manner.
