Description
Vorrichtung zur Messung der Taupunkttemperatur, der relativen und absoluten Feuchtigkeit bzw. des Wasserdampfdruckes der Luft Vorrichtung zur Messung der Taupunkttemperatur, der relativen und absoluten Feuchtigkeit bzw. des Wasserdampfdruckes der Luft.Device for measuring the dew point temperature, the relative and absolute humidity or the water vapor pressure of the air device for measuring the dew point temperature, the relative and absolute humidity or the water vapor pressure the air.
Zur Messung der Taupunkttemperatur, der absoluten Feuchtigkeit bzw. des Wasserdampfdruckes der Luft sind mehrere Einrichtungen bekannt, welche entweder aus getrennten Instrumenten bestehen oder die Anzeigen zweier Instrumente vermittels zweier mechanischer Vorrichtungen auf eine gemeinsame Zeigeranzeige zurückführen. Auch ist es bekannt, an der rückwärtigen Verlängerung des Hygrometerzeigers, der die relative Feuchtigkeit auf einer Skala anzeigt, ein Thermometer anzubringen, das mittels des Quecksilberfadens an einer Skala den Taupunkt abzulesen gestattet.To measure the dew point temperature, the absolute humidity or the water vapor pressure of the air several devices are known, which either consist of separate instruments or provide the readings of two instruments trace two mechanical devices back to a common pointer display. It is also known on the rear extension of the hygrometer pointer, the shows the relative humidity on a scale, attach a thermometer, which allows the dew point to be read off a scale using the mercury thread.
Vorliegende Einrichtung gestattet nun gleichzeitig die relative Feuchtigkeit, die Taupunkttemperatur und die absolute Feuchtigkeit bzw. den Wasserdampfdruck der Luft bei Verwendung nur einer mechanischen Übertragungsvorrichtung abzulesen.The present device now allows the relative humidity at the same time, the dew point temperature and the absolute humidity or the water vapor pressure of the Read air using only a mechanical transmission device.
Von den Abbildungen zeigt: Abb. z die Vorderansicht, Abb. 2 einen Schnitt nach A-B, Abb. 3 einen Schnitt nach C-D der Abb. 2. Hinter der feststehenden durchsichtigen Skalenscheibe a, auf welcher die Skalen für Temperatur und relative Feuchtigkeit sowie die Verbindungslinien aller Punkte gleicher absoluter Feuchtigkeit bzw. gleichen Wasserdampfdruckes der Luft in Kurven aufgetragen sind, ist auf der Welle c das durch das Hygrometer d drehbare Thermometer b befestigt. Dieses zeigt durch die Höhe seiner Flüssigkeitssäule auf der Skalenscheibe a die Temperatur und die absolute Feuchtigkeit bzw. den Wasserdampfdruck der Luft, durch die an seinem oberen Ende angebrachte Zeigerspitze die relative Feuchtigkeit der Luft an. Den Taupunkt kann man durch Verfolgung der jeweiligen Feuchtigkeitskurve bis zur Sättigungslinie auf dieser ablesen.Of the figures: Fig. Z shows the front view, Fig. 2 shows a Section according to A-B, Fig. 3 a section according to C-D in Fig. 2. Behind the fixed transparent dial a, on which the scales for temperature and relative Humidity as well as the connecting lines of all points of the same absolute humidity or the same water vapor pressure of the air are plotted in curves, is on the Shaft c is attached to thermometer b, which can be rotated by hygrometer d. This shows by the height of its liquid column on the dial a the temperature and the absolute humidity or the water vapor pressure of the air through which at his The pointer tip attached to the upper end indicates the relative humidity of the air. The The dew point can be set by following the respective moisture curve up to the saturation line read on this.
