Description

Kombinierter Temperatur- und Drehzahlmesser für beliebige rotierende Körper Das Patent 859 388 betrifft eine Vorrichtung zur Bestimmung der Drehzahl und der Temperatur rotierender Körper, bei der ein temperaturabhängiger Meßgenerator mit dem zu messenden Körper wärmeleitend verbunden ist, während ein zweiter, temperaturunabhängiger Meßgenerator zur Bestimmung der Drehzahl des rotierenden Körpers dient.Combined temperature and tachometer for any rotating body The patent 859 388 relates to a device for determining the speed and the temperature of rotating bodies at which a temperature-dependent measuring generator is connected to the body to be measured in a thermally conductive manner, while a second, temperature-independent Measuring generator is used to determine the speed of the rotating body.

Durch Quotientenbildung der von beiden Generatoren gelieferten Spannungen ergibt sich ein Maß für die Temperatur des rotierenden Körpers.By forming the quotient of the voltages supplied by both generators this gives a measure of the temperature of the rotating body.

Der in der Patentschrift 859 388 vorausgesetzte zweite temperaturunabhängige Meß generator ist entbehrlich, wenn man mittels des temperaturabhängigen Generators über einen entsprechend frequenzabhängigen Widerstand, z. B. eine Drossel, einen frequenzunabhängigen Generatorstrom erzeugt, der als Meßgröße für die Temperatur dient. The second temperature-independent one required in the patent specification 859 388 Measuring generator is unnecessary if you use the temperature-dependent generator via a corresponding frequency-dependent resistor, e.g. B. a throttle, a frequency-independent generator current generated as a measured variable for the temperature serves.

Ein geeigneter Wechselstrommesser mit geeichter Temperaturskala dient als Meßgerät. Derselbe Generator kann gleichzeitig zur Drehzahlmessung benutzt werden, wenn man die Generatorspannung jeweils über einen frequenzunabhängigen und einen frequenzabhängigen Vorwiderstand an die beiden Zweige eines geeigneten Quotientenmessers legt, z. B. Kreuz- oder T-Spulinstrument. Die Drehzahlmessung wird so spannungs- und damit temperatur- unabhängig. Der Quotientenmesser kann in Umdrehungen pro Minute geeicht werden.A suitable alternating current meter with a calibrated temperature scale is used as a measuring device. The same generator can be used for speed measurement at the same time, if you have the generator voltage over a frequency-independent and a frequency-dependent series resistor to the two branches of a suitable quotient meter places, e.g. B. Cross or T-coil instrument. The speed measurement is so voltage and thus temperature independent. The quotient meter can be in revolutions be calibrated per minute.
