Abstract :
Spectrum absorption type optic fiber gas sensor is a typical optical fiber gas sensor. The sensors use gas in the silica optical fiber (0.8 ~ 1.7 (including m) within the absorption peak, measurement of light intensity attenuation due to gas absorption, gas concentration. Common gases (such as CO, CH4, C2H2, NO2, CO2). There is frequently absorption line in the silica optical fiber transmission window. The device and receiving device of this wavelength light-emitting are ideal photoelectric sensor. So most of the gas concentration can be relatively high precision measurement by this way.
