Details

Service intended

P580 series are designed to monitor the gas density of closed SF6 tank (for switchgear). It is capable of the measuring real time status of SF6 gas density. These series are equipped with the relay contact which has the three configurable independent units to sense and measure the instantaneous pressure rise.
