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 ...

Wie funktioniert ein CO2-Sensor? -

NDIR is an industry term for " nondispersive infrared ", and is the most common type of sensor used to measure carbon dioxide, or CO2. An infrared (IR) lamp directs waves of light through a tube filled with a sample of air toward an optical filter in front of an IR light detector. The IR light detector measures the amount of IR light that passes ...

Inductive Sensors | Detection Method and Function

Inductive sensors function such that the sensor emits a high-frequency magnetic alternating field. When a metallic switching target approaches this magnetic field, energy is extracted from the alternating field through eddy current loss. In addition, ferromagnetic switching targets cause remagnetization loss. These losses are evaluated and the sensor switches when a defined threshold is ...
