GAS DENSITY MONITOR COMPRISING A TRANSMISSION ELEMENT, AND GAS DENSITY MONITORING METHOD

摘要

Density monitor for monitoring a gas density in a measuring volume, including a membrane which communicates with the measuring volume in such a way as to move in the measuring volume when a gas density changes, and a membrane movement detection device connected to the membrane, for converting a membrane movement into an electrical signal. The membrane movement detection device is coupled to the membrane by a transmission element for mechanically amplifying the membrane movement path.
