Abstract
A compensated opto-electronic gas sensor system comprises active apparatus utilizing electromagnetic radiation for sensing gas and sealed apparatus utilizing electromagnetic radiation for sensing gas. The sealed apparatus exhibits matched characteristics to the active apparatus and exhibits a sensing sensitivity dependent upon the wavelength of the electromagnetic radiation. The system further includes tunable wavelength source respectively coupled to the apparatus for sensing gas for supplying it with electromagnetic radiation of a selectable wavelength. A computer coupled to at least the sealed apparatus for sensing gas and is responsive to an output thereof for controlling the wavelength of the electromagnetic radiation such that the sealed apparatus for sensing gas exhibits an optimal sensitivity.
