FRICTIONAL RESISTANCE TYPE VACUUM MEASURING INSTRUMENT AND METHOD OF MEASURING PRESSURE BY USING SAID VACUUM MEASURING INSTRUMENT

摘要

the measurement is a gasreibungsvakuummeter used in the measuring head between electric driver in magnetic field rotation without contact, is stored. the rotation body is with the help of the driver in turn transferred above a predetermined minimum and drehfrequenz.as a result of gasreibung occurring drehzahlverminderungen of rotationsku00f6rpers by continuous or intermittent water of the driver from the compensated ac three phase generator.the measuring head of the gasreibungsvakuummeters are sensors arranged to capture drehfrequenz of rotationsku00f6rpers serve and signals to an electronic rechnereinheit pass, the temporal change of the rotation object drehfrequenz pressure of surrounding gas identified.the application of the gasreibungsvakuummeters higher printing to broaden, the rechnereinheit in addition with an electric signal with the temperature of the rotation object surrounding gas correlated, in the way is that the influence of the drive by the the rotationsku00f6rpers on the gas transferred heat on the measurement is corrected.
