Abstract
In a catalytic sensor, a bead is located within a can having an aperture in its front surface. The bead is surrounded by thermally insulating material such as glass fiber and a filter material is arranged between the bead and the aperture in the can. This acts to remove H2S or other inhibiting gases before they reach the bead and impair its performance. The thermally insulating material allows the filter material to be included whilst still permitting the bead to be operated at a high temperature.
