Description: It is used to monitor the density of SF6 gas in closed tanks, on-site display with switch contact. Raising an alarm when defined limit values have been reached, it is suitable for the monitoring of medium and high-voltage instruments. It can provide a variety of solutions such as supporting new substations and intelligent transformation of existing substations.
