Basically the technique of Current Reversal Mode (CRM) consists of applying a potential difference forward into the sensor and measuring the resultant electrical current. The next step is to apply the same potential difference backward into the sensor and re-measure the electrical current. The ratio between forward and reverse electrical currents is linearly proportional to the percentage of oxygen in the medium where the measurements are made. The proposal of this study was to apply the Current Reversal Mode into an automotive lambda sensor and to make measurements of oxygen percentage in the flue gases of aindustrial combustion chamber. Results did show that such technique is simple and accurate when the flue gases oxygen percentage were measured. This is an economic alternative for the monitoring industrial combustion for small farmers.
