Catalytic Comustible Gas Sensor - Combustible gas mixtures will
not burn until they reach an ignition temperature. However, in the
presence of certain chemical media, the gas will start to burn or ignite
at lower temperatures. This phenomenon is known as a catalytic combustion.
Most metal oxides and their compounds have these catalytic
properties....[from International Sensor Technology] |

Pellistors - Pellistors employ catalytic combustion to measure
combustible gases or vapors in air up to the Lower Explosive Limit (LEL)*
of the gas. The standard sensor consists of a matched pair of elements,
typically referred to as a detector and compensator (reference element).
