Résumé des résultats (Abstract) (Anglais)

SCR Crevoiserat SA has 12 years of experience in the design, production, marketing and sales of oxygen sensors and atmosphere regulators for industrial furnaces. An enormous emerging market is envisaged (about 500'000 units/year in Europe) in the field of anti-pollution control for domestic heating installations. New regulations will soon force a CO2 tax for domestic burners without control. Competitive control systems which exist now are either too expensive, or not reliable enough to meet the current needs of this new market. With these facts in mind, a new low-cost patented miniaturized oxygen probe was developed, which is perfectly able to meet all the needed requirements. It is self-calibrated, stable in time, highly resistant to the corrosion of combustion products and doesn't require any reference gas. However, the electronic control system, designed with standard ICs, must be redesigned in order to decrease the costs. The objectives of this Application Experiment is to develop a mixed signal ASIC (analog/AD-DA conversion/microcomputer) to analyze the signal coming from the miniaturized oxygen probe, in order to supervise the combustion in existing or new domestic heating systems. Compared to the current control system (19' enclosure, about 7500 ECUs) the new system should dramatically reduce the number of parts, the PCB space, the mounting and testing costs down to around 200 ECUs. In addition the new system allows savings of fuel or gas estimated between 5 and 8 %.
