Fiber-optical transformer of concentration of gas includes receiver of infrared radiation, wavelength of radiation of those is matched with wavelength of natural absorption of gas being analyzed, source of infrared radiation with wavelength that corresponds to spectral line of absorption of gas radiation from which is propagated by light guides of divider with formation of fluxes that go through one working channel in which measuring cuvette (open channel) is placed, and second working channel that is fiber-optical line with small losses of energy of radiation. In one working field one places measuring cuvette (open channel) with built-inn at outlet infrared receiver of radiation spectral sensitivity of which is matched with wavelength of natural absorption of gas under investigation and in second – fiber optical communication line to receiver of infrared radiation losses of energy of radiation there can be neglected. At that through measuring cuvette one pumps gas being analyzed and concentration of gas is determined by value of change of voltage at flux of radiation falling on photoreceiver, of frequency at outputs of devices at radiation flux falling on those. |
