P2.9.10 A Preliminary Study on Package of Catalytic Methane Sensor with Silica Aerogel

H. Y. Ma & E. J. Ding
The heat dissipation of catalytic combustion (pellistor) gas sensors through package has been neglected for a long time. Actually, the thermal isolation performances deserve to be taken into serious consideration. Due to the high sensing temperature and the quasi-closed metal package, a certain amount of thermal energy definitely lost from the pellistor sensors into ambience. If the thermal insulation ability of its package could be improved successfully, there would be a promising new approach to...
