Abstract: A gas sensor (10) exposed by diffusion to a gas flow and operable to measure the presence of a particular gas component of the gas flow. The sensor (10) comprises a base (20), a diffuser (34), a source (36), a detector (38), and a detection chamber (40). The diffuser (34) is interposed between the gas flow and the detection chamber (40). Thus, rather than directly exposing the source (36), detector (38), and other electronics to the full force of the gas flow, the gas is passed to and from the detection chamber (40) by diffusion. The source (36) radiates energy having a particular characteristic such that the energy is proportionally absorbed by the gas component. The detector (38) measures the presence of any unabsorbed energy and generates an output signal indicative thereof. The detection chamber (40) is coated with a material known to reflect the radiated energy.

Abstract translation: 气体传感器（10）通过扩散暴露于气体流并可操作以测量气体流的特定气体成分的存在。 传感器（10）包括基座（20），扩散器（34），源极（36），检测器（38）和检测室（40）。 扩散器（34）介于气流与检测室（40）之间。 因此，不是将源（36），检测器（38）和其它电子器件直接暴露于气流的全部力，而是通过扩散将气体传递到检测室（40）。 源（36）辐射具有特定特性的能量，使得能量被气体成分成比例地吸收。 检测器（38）测量存在任何未吸收的能量并产生指示其的输出信号。 检测室（40）涂覆有已知反映辐射能的材料。
