gas density meters and monitors are crucial safety devices used to measure the density of sulfur hexafluoride gas in closed tanks, such as switchgear, to ensure insulation integrity and detect leaks. These devices often use temperature compensation or a reference gas chamber to provide accurate, normalized pressure readings, typically triggering alarms if density drops below set limits.

What is a gas density monitor?
Gas density monitors
The gas density monitor is based on the principle of reference gas comparison and therefore no temperature compensation is necessary. It works electromechanically and is thus independent of electrical energy supply. Since no recalibration of switchpoints is needed, it operates maintenance-free.
