SF6 gas density monitor
1:An SF6density monitor warns operators of dropping levels that indicate contamination and/or leaks.
SF6 density monitors are temperature compensated and hermetically sealed to shield measurements from atmospheric pressure fluctuations and differences in mounting level.
2: SF6 density relay is widely used in the high and middle voltage switching power electric appliance industry. The product takes the advanced technology of the same industry at home and abroad, and has a unique advanced temperature compensation function. The product can detect and control the inner density of SF6 gas of the high and medium voltage switches and electrical equipment, to ensure the normal operation of the equipment, prevent the equipment from being damaged by the leakage of SF6 gas, and play a protective role for the equipment.
