Abstract
An explosion-proof gas sensor (,) with a flashback barrier (,) permeable to the gas to be measured between the measuring space (,) and the environment in an otherwise gas-impermeable housing (,) is described. The sensor provides reduced response time and higher signal sensitivity for the gas to be measured. A flashback barrier (,) is provided including a plurality of flexurally rigid fabric layers made preferably of metal, which are permeable to the gas to be measured, with an overall thickness of one to ten mm, an overall porosity of at least twenty percent by volume relative to the volume of the flashback barrier (,), and with a maximum number of one percent of all pores with a pore size larger than 240 &mgr;m.
