20190115· The temperature of the active bead must be high enough for the gas to be oxidized. While other gases can be oxidized at lower temperatures, in order to detect methane the temperature of the active bead must be 500°C or higher. If combustible gas is present, oxidation heats the active bead to an even higher temperature. The temperature of the untreated reference bead is unaffected by the ...

a very high temperature. When a combustible gas comes in contact with the sensor, the active bead begins to burn the gas causing it to increase in temperature. Since the reference bead is blind to the combustible gas, its temperature does not change. The increased temperature of the active bead creates an imbalance in the circuit and this imbalance is converted into a gas reading. Because ...

Most commonly used combustible gas sensors detect gas by catalytically oxidizing or burningthe gas on an active bead or – pellistor located within the sensor. While there are numerous variations, the underlying detection principle has not changed for the better part of a century. The catalyticbead sensor contains two coils of fine platinum wire which are coated with a ceramic or porous ...
