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.
