Abstract
In a system for detecting gaseous emissions (10), a housing (20) encases a mechanical member such as a flanged coupling (21) of a closed mechanical system which contains a fluid such as a gas (11) and receives gas (11) escaping through the flanged coupling (21). A sensor (26) extends through the housing (20) into a cavity (22) formed by the housing (20). A semipermeable membrane (28) forming the union between the sensor (26) and housing (20) allows gas (11) encased by the housing (20) to slowly pass from the housing (20) while preventing foreign matter from entering the housing.
