English term or phrase:VS cell
Au fait, c'est la paire VS cell/IP cell qui me pose problème dans le passage suivant :
The ECM controls the intensity and the direction of the pump current to the IP cell so as to maintain the certain voltage between both electrodes of VS cell (between LFUN and LFVM terminals), therefore, the ECM maintains the oxygen concentration to a specified value in the detection chamber.
Explanation: (pumping) IP cell: cellule de pompage
(sense/sensing) Vs cell: cellule de détection
Combining the narrow band and the pump cells allows the narrowband sensor to sense the mixture resulting from pumping oxygen into or out of the diffusion chamber. The resulting sensor is shown at left. To save wires, the "Vs (sense)" and the "Ip (pump) cells" are connected together - they share a common reaction surface anyway, so this isn't a problem.
courant de pompage nécessaire pour égaliser la diffusion de l'oxygène entre la "cellule de détection" et la "cellule de pompage" d'une sonde dont la sortie est proportionnelle à la concentration d'ions oxygène
