Operating principle ‐Electrochemical-type gas sensor

The oxidation potential of CO gas (as expressed in Equation 1) is lower than the oxidation potential of the electrode(2H+ + 2e-⇔ H 2), oxidation of CO has less noble potential than deoxidization. Since this reaction occurs easily, no external energy is needed to stimulate the sensor’s chemical reaction, unlike with three-electrode type sensors. As a result, this two-electrode type ...

GAS LEAKAGE SENSOR | MODEL CONSTRUCTION

When gas reached a certain concentration (2,1—9% density natural gas in the air), the sensor resistance DG1 decreases to such a value that the voltage at the non-inverting input of the comparator becomes less than the inverting. In this mode, the voltage at terminal 9 of the comparator is close to zero. Transistor VT1 opens, piezoelectric capsule HA1 generator CC alerted to gas hazards.
