Quantitative gas circuit breakers Density Monitors

Description: Sf6 density pressure switch is an economical and reliable way to monitor SF6 gas density and leakage over a wide temperature range. These instruments are used to monitor SF6 gas density in sealed tanks. They are applied to indicate gas density and to provide a signal outputs when the density reaches preset threshold values.
