Description
Rodiometer für glotte Oberflächen hoher Raflexion Die Erfindung betrifft ein Rodiometer zur Meßung von flöchentemparcturen on glotten Oberfl@chen hoher Reflexion mit einem Objektiv, einem Tamperoturstr@hlungsempfönger und einem Anzeigegeröt.Rodiometer for flat surfaces of high reflection The invention relates to a rodiometer for measuring surface temperatures on glottal surfaces of high reflection with a lens, a tamperotur receiver and a display unit.
Die Meßung von Oberflöchentemperoturen durch Bestimmung der mittleren Temperotur größerer Oberflöchenteile wird zweckmößig mit den bekonnten Rodiometern vorgenommen, bei denen die Basis des auf dem Objekt endenden Sichtkegels des Meßobjestives, dos auch aus einer Lochblende bestehen konn, dio zu messende Flache bestimmt. Dadurch kann auf einfache Weise die mittlere Temperatur einer Meßflöche son der Gr@ßenordnung einiger cm2 gemessen und in den Föllen, in denen eine hohe örtliche Auflösung der Tempoerotur nicht benötigt wird, die Meßgenouigkeit erhöht werden.The measurement of surface temperatures by determining the mean The temperature of larger surface parts is expedient with the well-known rodiometers made, in which the base of the cone of vision of the measuring objective ending on the object, can also consist of a perforated diaphragm, which determines the area to be measured. Through this can easily determine the mean temperature of a measuring surface of the order of magnitude of a few cm2 and in the fills where there is a high spatial resolution of the Tempoerotur is not required, the measuring accuracy can be increased.
Diese Meßmethode ist nur bedingt verwendbar, wenn beispiebweise die Oberflöche von blonken, glotten Metollen gemessen werden soll, do in diesem Fall der Refieionskoeffizient groß und danit der Eissionskoeffizient klein wird, da gier in hohem Moße die von der Meßflöche roflektierte Um@@bung gemessen wird, was zu verfölschten Meßergebnissen f@hrt. Andererseits ist es oft, beispielsweise bei Kolonderwolzen, nicht möglich, durch Aufbringen von Schichten hoher Emissionskoeffizientsn die Emissionseigenschoften zu verbessern.This measuring method can only be used to a limited extent if, for example, the Surface of blonken, glotten metollen should be measured, do in this case the reflection coefficient becomes large and then the emission coefficient becomes small because greed to a large extent the um @@ exercise reflected by the measuring surface is measured, which leads to leads to falsified measurement results. On the other hand, it is often, for example with Kolonderwolzen, not possible, by applying layers of high emission coefficients, the emission properties to improve.
Es stellt sich somit die Aufgabe, eine Anordnung zu entwickeln, mit der auch bei glatten Oberflöchen hoher Reflexion eine genaue Strohlungsmessung möglich ist.It is therefore the task of developing an arrangement with which enables precise radiation measurement even with smooth surfaces with high reflections is.
Dies. Aufgnbo bst die Erfindung dadurch, da ein dunner, mit dem Objektiv federnd fest-verbundane reflonstreifen im Sichtkegal des Objektivs derort dufgespunnt ist, doß die Bosis des Sichtkegels vellstöndig ouf dem feflonstreifen liegt.This. The invention is enhanced by the fact that it is thin with the lens resilient, firmly connected reflon strips in the viewing area of the lens where there is a scent is, that the bosis of the cone of vision lies completely on the feflon strip.
Der Vorteil dieser Anordnung liegt dorin, doß der Teflonstreifen, wenn er ouf eins glotte Obsrflöche hoher Reflexion aufgelegt wird, deren Temperctur annimmt und seinerssits eine Strchlung dussendet, so daß jetzt die mittlexe Temper@tur einfach me@bor ist. Dabei ist es gleichgültig, ob sich die Orerflöche bewegt oder nicht, da Teflon einen sehr geringen Reibungskosffizientem hat. Auf diese Weise wird der Enissionskoeffizient der glctten Oberflöche hoher Reflemion definierbor vergrößert und die Strchlungs messung ouch bei diesen Oberrflöchen nöglich.The advantage of this arrangement is that the Teflon strip, when it is placed on a glotty obscurus of high reflection, its temperature assumes and, on the other hand, sends a flicker, so that now the mean temperature simply me @ bor is. It does not matter whether the Orerflöche moves or not, as Teflon has a very low coefficient of friction. In this way the emission coefficient of the smooth surface of high reflection is defined enlarged and the flow measurement is also possible with these surfaces.
Es ist zwar bekannt, Kontokt@ermometes wit Teflon zu ummonteln und mit solchen Thermometern bei bionken beweglichen Oberflöchen die Temperotur zu messen. Hier hat dos Teflon die Aufgabe der Wörmecbleitung aus einem kleinen Bereich, wdhrend in einer Anordnung nach der Erfindung eine Meßwertwondlung eingescheltet wird. wodurch ein großer Flöchbereich der Messung zugönglich wird.It is known to ummonteln and account @ ermometes wit Teflon to measure the temperature of bionken movable surfaces with such thermometers. Here dos Teflon has the task of heat transfer from a small area, while In an arrangement according to the invention, a measured value winding is switched on. through which a large surface area of the measurement becomes accessible.
In der Zeicbnung ist ein Ausfubrungsbeispinl der Erfindung schematisch dargestellt.An embodiment example of the invention is shown schematically in the drawing shown.
Ein einen Tenperoturstrohlungsempfönger entheltendes Rodiometer # mit einem Anzeigeinstrument 2 und einem, die Temperoturstrchlung ouf den Temperatuzstrdhlungsempfönger richtendes Objektivß, dos ouch ous oier Lochblende bestehen konn, mit einem Sichtkegel, 4 ist miteinem federnd-fost mit dem Objektiv 3 verbundenen Stützgestell 6 @rsehen, in dem ein Teflonstreifen 5 oulgespannt ist. Druckfedern 55 sorgen für die Spreizung des Stutzgestelis 6, so daß der Teflon^ streifen 5 glott oufgespannt ist, rier Teflonstrcifen 5 ist so bemessen.@@ß der Sichtkegel 4 des Rodiometers voll ouf dem Streifen liegt. Wird diese Anordnung auf eine Wolze 7 @ufgedruckt, dann wird durch die Wirkung der Federn das Teflon glott auf diese Walze gezogen. Da der Reibungskoeffizient des Teflonstreifens gering ist, entsteht auch bei beweglichen Walzen 7 nur venig Reibungswärme, die jedoch durch eine Eichung des Rodiometers eleminiert werden konn. Die von der Innenseite des Teflonstreifens @usgehende Strahlung, die eine Funktion der temperatur ist, wird vom Objektiv des R@@iometers oufgenommen, ouf den To@per@turstrchlungsempfönger gerichtet und zur Anzeige g@brocht.A rodiometer containing a tenperoture radiator # with a display instrument 2 and one, the Temperoturstrchlung on the Temperatuzstrdhlungsempfönger judging Lens, there can also be oier pinhole diaphragm, with a cone of vision that is 4 with a spring-loaded support frame 6 connected to the lens 3, in which a Teflon strip 5 is oulgespannt. Compression springs 55 ensure the expansion of the support frame 6, so that the Teflon ^ strip 5 is stretched open, rier Teflon strip 5 is dimensioned so. @@ ß the cone of vision 4 of the rodiometer lies fully on the strip. If this arrangement is printed on a Wolze 7, the effect of the Springs the Teflon glott pulled onto this roller. Since the coefficient of friction of the Teflon strip is small, there is little frictional heat even with movable rollers 7, which, however, can be eliminated by calibrating the rodiometer.
