IR SF6 density sensor Siemens

In this paper, the Ir-modified MoS2 monolayer is suggested as a novel gas sensor alternative for detecting the characteristic decomposition products of SF6, including H2S, SO2, and SOF2. The corresponding adsorption properties and sensing behaviors were systematically studied using the density functional theory (DFT) method. The theoretical calculation indicates that Ir

  • SF6 Air Sensor Analysis Siemens - rvcarcare.nl

    SF6 Air Sensor Analysis Siemens. In previous articles, we discussed the characteristics of SF6 (sulfur hexafluoride) gas which make it advantageous for use in medium- and high-voltage electrical equipment. Here we compare the features of conventional medium-voltage load interrupter switches operating in air with those of operating in an SF6

  • Gas density monitors and gas density sensors for SF6

    Trafag gas monitoring devices measure the gas density directly, i.e. SF 6 Gas Density Monitors, with the unique gas density reference principle or the patented quartz tuning fork technology, i.e. SF 6 Gas Density Sensors, or by combining both principles, i.e.SF 6 Hybrid Gas Density Monitors. They thus offer the most reliable solution on the market by directly measuring theSF 6 gas density.
