sf6 gas density monitor
sf6 gas density monitor Description:
When our SF6 gas density is connected to the closed system, the system equipment is filled with SF6 gas. When the SF6 gas density reaches the specified value, the pointer of the density controller points to the filling gas pressure. When the temperature of the working environment changes, although the density of SF6 gas does not change, the pressure of SF6 gas will change with the change of temperature, and the pointer on the density should be deflected with the change of pressure. The change of the SF6 gas pressure is compensated by the temperature compensation device inside the density so that the pointer does not deflect. Only when the SF6 gas leaks in the system, causing the density to drop, the pointer of the SF6 gas density is deflected to monitor the density of the SF6 gas in the closed container, and the gas density can be displayed on site, when the density value reaches the set value. Alarm for monitoring and control of high pressure systems. Prevent damage to the equipment when SF6 gas leaks, thus protecting the equipment and ensuring normal operation of the equipment.
