Gas detector finds application in a wide range of scientific and technical fileds. Gas detectors are commonly used to determine the component gasses in automobile exhaust so as to measure the effectiveness of pollution control devices. Gas detection devices are also used for a variety of applications in oilwell drilling technology. A gas detector generally comprises a sensor mounted on the ceiling to detect existence of the gas. When the sensor detects that the gas concentration in a site such as the house or the like exceeds a predetermined limit, the gas safety detector emits an alarm signals. Infrared gas sensors have been widely used for either detecting the presence of a gas or measuring the concentration of a gas in a particular environment. Infrared gas sensors are based on the principle of the selective absorption of infrared radiation by gases. Infrared gas sensors generally comprise one or more radiation sources, such as thermal radiators, one or more absorption sections, wavelength-selecting elements and one or more radiation detectors, which convert the optical signal into an electrical measurement signal. Pulsed discharge detectors ionize a discharge gas in a chamber to produce photons, introduce a sample gas to be tested and measure ionization currents of electrons produced from interaction of the photons with the sample gas. Gas detectors which operate and monitor gas concentrations in a fixed location are known in the industry as point detectors.
