AP 1018: Understanding catalytic LEL combustible gas ...

Figure 4: Catalytic “Pellistor” LEL sensors detect combustible gas by catalytic oxidation. When exposed to gas the oxidation reaction causes the “active” bead to heat to a higher temperature. Pellistor LEL sensors require oxygen to detect gas! Figure 5: The active “Pellistor” bead is strung onto a coiled platinum filament wire.

Portable Gas Detection IR Catalytic Combustible Detection

When gas reaches the catalytic bead sensor, combustion occurs and energy releases. This energy release causes temperature increase, changing electrical resistance inside the sensor that is reported by a change in sensor signal. Catalytic bead combustible sensors are fast, reliable and can monitor a wide range of combustible gases, including ...
