resistive type sensor, for measuring the relative concentrations of the reactive species, in the temperature compensated.

摘要

The invention relates to an oxygen sensor of the resistive type for measuring the relative concentrations fluids of reactive species fluids. / p & & p & on a same substrate are: - a sensitive element 2, the resistivity of which is sensitive to an excess of one of the reactive species; - a thermistor 3 mounted in the resistor bridge 3 with the sensitive element 2; - a heating resistor 4 which determines the minimum point of operation of the sensor. / p & & p & the invention is particularly applicable to the sensors to oxygen.
