Sensing Resistance in air
Sensitivity Factor
A minimum value of 85mW ensures sufficient sensitivity to ethanol. Heating powers above 120mW can cause permanent
damage to the sensor when ambient temperatures exceed 120°C.
Heating resistor values from sensors out of production range between 90 and 110 Ohm. Due to material properties of the
heating resistor its value increases during operating life. This behavior has to be taken into account in the application
design.
