Description
Signaleinrichtung hei li'leßgeräten Die Erfindung betrifft eine Signaleinrichtung bei Meßgeräten. Ihre Wirkung beruht darauf, daß kalte und warme Körper von dem Meßwerk des Meßgerätes einander genähert oder voneinander entfernt werden, wodurch, eine Thermokraft oder ein Widerstandswert und dadurch die Stromverhältnisse in einem Relaiskreis geändert werden.Signal device for measuring devices The invention relates to a signal device for measuring devices. Their effect is based on that cold and hot body of the measuring mechanism of the meter brought closer together or away from each other, whereby a thermal force or resistance value and thereby the current ratios are changed in a relay circuit.
Die Zeichnung zeigt einige Ausführungsbeispiele. Das Meßwerk des Meßgerätes mit dem Zeiger z ist mit einem am Bügel b befestigten Thermoelement t (Abb. i) oder statt dessen mit einem feinen Widerstandsdraht w (Abb. 2) versehen. Heizspulen h, und h2, die ebenfalls verstellbar sein können, wirken auf t oder w ein, sobald diese temperaturempfindlichen Teile in die Spulen eintauchen oder an ihnen vorbeistreifen. Hierdurch wird ein Relais y in Tätigkeit gesetzt.The drawing shows some exemplary embodiments. The measuring mechanism of the measuring device with the pointer z is provided with a thermocouple t attached to the bracket b (Fig. I) or instead with a fine resistance wire w (Fig. 2). Heating coils h and h2, which can also be adjustable, act on t or w as soon as these temperature-sensitive parts immerse themselves in the coils or slip past them. This activates a relay y.
Die Signaleinrichtung behindert den Zeiger nicht in seiner Bewegung. Er kann infolgedessen anmehreren Stellen gleichartige oder verschiedenartige Relaiswirkungen auslösen. Je nach der Erhitzung durch die Heizspulen hi, h2 wird die Wirkung schneller oder langsamer eintreten, so daß im Bedarfsfalle auch eine Verzögerung möglich ist. Läßt man das wärmeempfindliche Element in eine Flüssigkeit f (Abb. 3) eintauchen, so ist die Wirkung plötzlicher.The signaling device does not hinder the movement of the pointer. As a result, it can have relay effects of the same or different types in several places trigger. The effect is faster depending on the heating by the heating coils hi, h2 or enter more slowly, so that a delay is possible if necessary. If the heat-sensitive element is immersed in a liquid f (Fig. 3), so the effect is more sudden.
Die Einrichtung kann auch in umgekehrter Weise arbeiten, indem die Teile sinngemäß miteinander vertauscht sind. Ebenso kann die Wirkung durch Temperaturänderung derart stattfinden, daß erhitzte Körper abgekühlt werden.The device can also work in reverse by adding the Parts are mutually interchanged accordingly. The effect can also be caused by a change in temperature take place in such a way that heated bodies are cooled.
