AAN 104 How Electrochemical Gas Sensors Work

AAN 104 How Electrochemical Gas Sensors Work Alphasense toxic gas sensors are electrochemical cells that operate in the amperometric mode. That is, they generate a current that is linearly proportional to the fractional volume of the toxic gas, such as CO or H 2S. Figure 1 shows schematically the structure of a toxic gas sensor. Figure 1. Schematic diagram of electrochemical toxic gas sensor ...

How electrochemical CO sensors detect gas. Gas that enters the sensor undergoes an electrochemical reaction that causes a change in the electrical output of the sensor. The difference in the electrical output is proportional to the amount of gas present. Gas enters the sensor through an external diffusion barrier that is porous to gas but nonporous to liquid. An internal organic vapor filter ...
