RESISTIVE TYPE SENSOR, MEASUREMENT OF CONCENTRATIONS RELATING TO REACTIVE FLUID SPECIES, TEMPERATURE COMPENSATION

摘要

The invention relates to a resistive type oxygen sensor for measuring fluid relative concentrations of fluid reactive species. On the same substrate are implanted: a sensitive element whose resistivity is sensitive to an excess of one of the reactive species; a thermistor 3 mounted on a resistance bridge 3 with the sensitive element 2; - A heating resistor 4 fixing the minimum operating point of the sensor. / P P The invention is particularly applicable to oxygen sensors. / P
