ADVANCED SENSORS FOR INSPECTING HYDROGEN LEAK DETECTION

The development of leak detection as a method of detecting leaks using penetrating substances is closely linked with new directions in devel oping gas analytical sensors. These sensors cannot be developed withou t applying modem microelectronic technology which makes it possible to produce under mass production conditions large batteries of cheap dev ices reducing at the same time the energy and material requirement of analyzers. The combination of these qualities with high sensitivity, s electivity, and operating speed makes it unsuitable for developing new and compact leak detectors constructed on microelectronic components.
