CATALYTIC PELLISTORS GAS SENSORS - Nenvitech

A Pellistor operates on the principle that when a combustible gas/air mixture is in contact with the catalyst surface, maintained at about 500°C as current is passed through it in a Platinum coil, combustion occurs. The heat generated increases the temperature of the bead, which in turn changes the resistance of the coil.Get price

R-143. It is used as a refrigerant either by itself or more commonly as a component of blended mixtures. Unlike CFCs used as refrigerants, trifluoroethane has no chlorine atoms and is therefore not an ozone-depleting chemical, though its high chemical stability and infra-red absorbency make it a potent green-house gas with a global warming potential of 4300, higher than many other commonlyGet price

Streamer and leader formation in sf6 gas and sf 6 mixtures under

Dec 14, 1986 · For pt.I see ibid., vol.12, p.2351 (1986). This second paper on the breakdown mechanisms in electronegative gases under non-uniform field conditions deals with the development of the leader type of discharge, the emphasis being laid on details of the streamer to leader transition, which is found to be very much different from the corresponding process in air.Get price
