Latest Patents
One of Hisashi Sasaki's latest inventions is an NOsensor control apparatus. This apparatus is connected to an NOsensor, which includes a first pumping cell and a second pumping cell. The second pumping current flows through these cells, corresponding to the NO concentration in the gas being measured. The NOsensor control apparatus features a first pumping current detection unit, a second pumping current detection unit, and an oxygen concentration calculation unit. This unit calculates oxygen concentration based on the first pumping current, corrected according to the pressure of the gas being measured. Additionally, it includes an NO concentration calculation unit that determines NO concentration based on similar parameters.
Another notable invention is the NOx sensor control apparatus. This apparatus includes a NOx sensor with a heater and an oxygen concentration detection cell, along with the first and second pumping cells arranged sequentially. The control apparatus detects the first and second impedances of the respective cells and corrects the output of the first pumping cell based on the impedance deviation.
