Description
BeschreibungDescription
Minima-Thermometer als Einschlußthermometer werden im technischen Bereich(Labor usw.)verwendet. Die Wirkungsweise ist folgendermaßen: daß sich in der Kapillare,und zwar innerhalb der Anzeigeflüssigkeit , ein Glasstift(Schwimmer) befindet,der beim Zurückweichen der Flüssigkeit,also bei Temperaturrückgang, durch die Oberflächenspannung der Fadenkuppe(Meniskus) mitgezogen wird,beim Ansteigen dagegen liegen bleibt. Demzufolge zeigt der Glasstift mit seinem dem Füllgefäß abgewandten Ende stets den innerhalb eines bestimmten Zeitraumes eingetretenen Temperatur-Tiefstand an.Zur Neueinstellung wird das Thermometer auf den Kopf gestellt, der Schwimmer gleitet dann auf Grund seiner eigenen Schwere innerhalb des Flüssigkeitsfadens bis an die Oberflächenhaut der Fadenkuppe heran.Minima thermometers as enclosed thermometers are used in technical areas (laboratory, etc.). The way they work is as follows: in the capillary, within the display liquid, there is a glass pin (float) which, when the liquid recedes, i.e. when the temperature drops, is pulled along by the surface tension of the thread tip (meniscus), but remains in place when it rises. As a result, the end of the glass pin facing away from the filling vessel always shows the lowest temperature that has occurred within a certain period of time. To reset, the thermometer is turned upside down, and the float then slides due to its own weight within the thread of liquid up to the surface of the thread tip.
Die Bauweise dieses Minima-Thermometers(Zylinderrohr, Gabelgefäß,Milchglasskale) ist auf Grund seines speziellen Einsatzes im Labor nicht für den Gebrauch im Haushalt geeignet,da eine hohe Bruchgefahr und keine Halterung vorhanden ist.Bedingt durch die feine Skaleneinteilung besteht eine erschwerte Ablesbarkeit.The design of this minima thermometer (cylindrical tube, forked vessel, frosted glass scale) is not suitable for use in the home due to its special use in the laboratory, as there is a high risk of breakage and no holder. Due to the fine scale divisions, it is difficult to read.
Der im Schutzanspruch angegebenen Erfindung liegt das Problem zugrunde,ein Minima-Thermometer zu schaffen, welches durch einfache Handhabung,geringe Bruchgefahr, gute Ablesbarkeit im Haushalt einsetzbar ist.The invention specified in the protection claim is based on the problem of creating a minima thermometer, which can be used in the home due to its ease of use, low risk of breakage, and good readability.
Diese Problem wird mit den im Schutzanspruch aufgeführten Merkmalen,daß das Kapillarrohr mit Füllgefäß(2),gefüllt mit einer transparenten Flüssigkeit,in der sich ein Glasstift(3) befindet,auf einer Grundplatte(1)mit Skalenabbildung befestigt ist,und daß die Grundplatte(1) mit zwei Bohrungen(4,5) versehen ist,gelöst.This problem is solved with the features listed in the protection claim, that the capillary tube with filling vessel (2) filled with a transparent liquid in which a glass pin (3) is located, is attached to a base plate (1) with a scale image, and that the base plate (1) is provided with two bores (4, 5).
Mit der Erfindung wird erreicht,daß das Thermometer leicht zu bedienen,durch seine Größe gut ablesbar und durch eine stabile Grundplatte einer geringen Bruchgefahr ausgesetzt ist.The invention ensures that the thermometer is easy to use, easy to read due to its size and has a stable base plate which means it is less likely to break.
Ein Ausführungsbeispiel wird an Hand der Abbildung erläutert.An example of implementation is explained using the figure.
Die Abbildung zeigt das Thermometer mit der stabilen Grundplatte(1),das Kapillarrohr mit Füllgefäß(2), mit dem in der Flüssigkeit schwimmenden Glasstift(3), und die zwei Bohrungen(4,5).The illustration shows the thermometer with the stable base plate (1), the capillary tube with filling vessel (2), with the glass pin floating in the liquid (3), and the two holes (4,5).
