SF6 gas density
  There is curves for solving problem of density changes with temperature to avoid a problem of temperature compensation is accurate.
Product introduction:
   SF6 gas density main used for high voltage electric equipment form a complete set which taking gas as insulation arcing medium.to monitor the density of SF6 gas that in In a sealed container,it is widely used in SF6 circuit breaker,SF6 Ring Main Unit,SF6 C-GIS,SF6 pole top switch,transformer and mutual inductor.
Product features:
 1.Good sealed performance,all products do strict sealing test through helium mass spectrometer, yearly gas leakage rate less-than ≤1×10-9 m bar.L/s.)
 2. According to the SF6 gas 20 ℃ when the pressure value is equal to the density of the gas, SF6 gas pressure varies with the temperature.A disc on the first curve is in different temperature curves of pressure value to display 0.01 Mpa SF6 gas density value;Dial on the second curve is under different temperature curves of pressure value to display 0.03 Mpa when SF6 gas density value;Article 3 the curve on the dial is under different temperature curves of pressure value to represent the SF6 gas density value is 0.06 Mpa
 3.Accurate display density value and can avoid the error of temperature compensation which display density through temperature compensation)
 4.It is cost-effective and upgrade of old pressure gauge.
Main technical parameter:
   Range:0-0.1Mpa
Absolute Pressure:1-2.0bar
Accuracy:1.5degree
Temperature:-40℃～60℃
Relative humidity:≤95%RH
Sealing property:≤1×1015Mpa.m3/s
Connection：M20×1.5 、  3/8、M14x1.5<Can produce according to customers requirements>
 Installment and use：
The SF6 density must be installed vertically on the interface of the device.
2.The relay must be tightened by spanner at the sate of the joint when it is installed.)
3.Please lift and lower pressure slowly in case of damaging the SF6 density.
