Sensor arrangement for detecting gases, e.g. natural gas or carbon mon:oxide

摘要

Sensor arrangement for detecting gases comprises: (a) at least a first gas sensor (GS1); (b) a catalyst filter (K) to convert interfering gases into non-interfering gases, the filter being spaced apart from the gas sensor (GS1); and (c) a heat source (H) to heat the catalyst filter (K).
