  • Interference-compensating NDIR gas sensor for measuring acetylene
    Patent number: 9285308
    Abstract: A gas sample separated from transformer oil is circulated through an NDIR gas sensor system which obtains an acetylene concentration by calculating a detected acetylene concentration obtained by an absorption biased (“AB”) NDIR acetylene gas sensor, calculating a detected carbon dioxide concentration obtained by an AB NDIR carbon dioxide gas sensor, calculating a detected water vapor concentration obtained by an AB NDIR water vapor NDIR gas sensor and then determining the acetylene concentration from the detected acetylene concentration through use of the detected carbon dioxide and water vapor concentrations to compensate for their interference.
    Type: Grant
