CARBON QUANTITY DETECTING SENSOR WITH INCREASED DETECTING PRECISION

摘要

A carbon quantity detecting sensor for continuously detecting a carbon quantity of measuring gases with increased precision using a simplifier structure is disclosed. The sensor includes at least a proton conductive body composed of a solid electrolyte body having a proton conductivity, an electrode pair composed of a measuring electrode and a reference electrode formed on the proton conductive body at opposing surfaces thereof respectively, and a power source for applying at least one of a given current or a given voltage across the electrode pair. The measuring gases electrode is exposed to the measuring gases and the reference electrode is isolated from the measuring gases. This enables the carbon quantity of measuring gases to be detected with increased precision for a long period of time without causing a carbon component to accumulate on a surface of the measuring electrode due to an electrochemical reaction.
