Summary
SF6 density monitor is used for monitoring and controlling SF6 density (pressure) in substation equipment, where SF6 is used as insulating medium. To ensure the safe operating, the system will output alarm signal and deadlock alarm signal when SF6 leaking.
Applications
SF6 circuit breakers
ring network cabinets
inflatable cabinets
column switches and mutual inductors
Feature of SF6 Gas Densimeter
Stainless steel housing and air connection for gas density meter,beautiful appearance and high protection level.
Gold-plated contacts for gas density meter, high opening power, small contact resistance.
Imported temperature sensing element, high precision and stable performance.
Silver fiber and laser welding are used, and the sealing performance is ensured by helium mass spectrometry leak detection.
A variety of interface connection, can be matched with various types of self-sealing valves, suitable for a variety of SF6 equipment at home and abroad.
