Sulfr hexafluoride Gas or Sulfur Hexafluoride Gas Properties | Electrical4U

History of sf 6Chemical Properties of Sulfr hexafluoride GasElectrical Properties of sf6 gas Gasgaz sf6 or sulfur hexafluoride gas molecules are combined by one sulfur and six fluorine atoms. This gas was first realized in the year 1900 in the laboratories of the Faculte de Pharmacie de, in Paris. In the year of 1937, General Electrical Company first realized that sf 6 gas could be used as gaseous insulating material. After the Second World War, i.e. in the middle of 20th century, the popularity of using sulfur hexafluoride gas as an insulating material in electrical system was rising very r...

It can detect the detect carbon monoxide density from 10ppm to 1000ppm and flammable gases density from 100ppm to 10000ppm. MQ9 has an internal heater which starts warming up if a 5V voltage is applied. The internal resistance of this sensor changes as the density of the detectable gases changes. This value can be read by a simple circuit.
