Abstract
The invention relates to a sensor system for determining the moisture content in a gas to be measured. On the basis of two current saturation ranges during the determination of the moisture content with the aid of a zirconia sensor, according to the invention two spatially separated sensors are provided, which are operated at different voltages corresponding to the individual saturation current ranges. By further evaluation of the signals, this permits a very precise, on-line determination of the moisture content of the gas to be measured.
