A solid state sensor consisting of at least two electrodes associated with a solid substrate exhibiting ionic conduction. The two electrodes are connected in an electrical circuit which facilitates measuring of peaking voltage signals generated by the sensor, the sensor being capable of generating peak electrical signals of more than a hundred millivolt while exposed to hot combustion gases resulting from air fuel mixtures changing between lean and rich fuel-air mixtures.read more

System, apparatus, and method for measuring an ion concentration of a measured fluid
TL;DR: In this article, the pump current through a pump cell is switched between a constant positive current and a constant negative current when upper and lower thresholds of the output signal are reached, and the pulse width ratio of the square wave produced by the varying current is compared to a pulsewidth ratio function derived from a calibration procedure to determine the ion concentration of the measured fluid.
