MEM6 Hydrogen-Compensated 4-Electrode-Sensors

ELECTROCHEMICAL GAS SENSORS. 3) Calibration and Calculation Three measurements and two different gas mixtures are needed for the calibration. In the case of an H2-compensated CO sensor, the first gas mixture consists solely of CO gas, whereas the second is a mixture of both CO and H2. Definitions The 4-electrode sensor gives two signals: A current at the sensing pin (ISens) and a …

· As an example the Figaro company’s CO gas electrochemical sensors works on this simple premises of monitoring the oxidation or reduction of a gas on an electrode surface. It works as an amperometric (detections current/time) cell with two electrodes, the working (sensing) electrode and the counter (pseudo reference) electrode which are placed in between a layer of electrolyte (H + ).

Gassensor – Wikipedia

Problematik chemischer Sensoren. Das Gebiet der chemischen Sensoren ist relativ jung. Während Sensoren zum Messen physikalischer Größen wie beispielsweise Temperatur, Druck und Beschleunigung wasser- und luftdicht verschlossen sind, steht ein chemischer Sensor wie der Gassensor in direkter Wechselwirkung mit seiner Umgebung. Dadurch ist er auch wesentlich …
