insulating gas Gas Measurement Theory - MBW Calibration AG

MBW has more than forty years of experience measuring water vapor (moisture, humidity, dew point, frost point, ppm v, ppm w) in SF 6 gas applications. We have supplied thousands of dew point measurement systems, many of which remain in daily use despite being in use for 20…30 years. Our fundamental measurement technology provides the highest possible accuracy and long-term stability so that engineers can depend on good measurements when they need them, without regular and expensive sensorGet price

Measuring Dew Point and Moisture in sf6 gas Gas

Most Gas Insulated Equipment (GIE) manufacturer recommend minimum and maximum tolerances for certain variables within the gas, including moisture, gas decomposition, and purity of Sulfr hexafluoride. A typical dew point range for servicing the gaz sf6 equipment is -50…-20 °C. Pure Sulfr hexafluoride may be even drier.Get price
