Product Overview
After the YSF-100II gas density controller is connected to the closed system, SF6 gas is filled into the system equipment. When the SF6 gas density reaches the specified value, the pointer of the density controller points to the rated working pressure. When the working environment temperature changes, although the density of SF6 gas does not change, the pressure of SF6 gas will change with the temperature change. The pointer on the density controller should have deviated with the pressure change.
At this time, the temperature compensation device inside the controller compensates for the change in SF6 gas pressure to prevent the pointer from deviating. Only when SF6 gas leaks in the system, causing a decrease in density, will the pointer of the SF6 gas density controller deflect.
It is used to monitor the density of SF6 gas in a closed container and can display the gas density on site. When the density value reaches the set value, an alarm will be triggered. It is suitable for monitoring and control of medium voltage systems. To prevent damage to equipment in the event of SF6 gas leakage, thereby providing protection for the equipment and ensuring its normal operation.
Product Features
Using imported temperature compensation components, the measurement accuracy is high and the performance is more stable.
Adopting AISI304 stainless steel sealed case, the appearance is exquisite and the protection level is high.
Use AIS1316 stainless steel to make the gas pipeline connection fittings system.
Adopting a plug-in junction box, the wiring is convenient, reliable and stable.
Using argon gas protection and laser welding, leak detection is ensured through helium mass spectrometry sealing to ensure sealing performance.
Adopting a gold-plated electrical contact switch design to achieve precise and stable SF6 gas density monitoring function.
Adopting multiple interface connection methods, it can be matched with various self sealing valves.
Up to three pairs of contacts can be used to achieve multiple options such as overpressure alarm, dual alarm, or dual locking, making monitoring safer and more reliable.
