MESURING DEVICE FOR DETERMINING THE FILL QUANTITY OF AN SF6 GAS IN AN ISOLATION CHAMBER OR A SWITCHGEAR, AND CORRESPONDING METHOD

摘要

A measuring device (1) according to the invention for determining the fill quantity of an SF6 gas in an isolation chamber (2) has a pressure transducer (15), a temperature measuring element (13), and a processing device (16) for determining the fill quantity of the SF6 gas from the measured pressure value and the associated measured temperature value, wherein the measuring device (1) seals a corresponding opening in the isolation chamber (2) and both the pressure transducer (15) and the temperature measuring element (13) are acted on directly by the SF6 gas to be measured.
