| Zusammenfassung: | The present invention relates to improvement in a gas sensor having a coiled heater electrode.
A central electrode is arranged in a coiled heater electrode They are buried in a SnO-based inner area and the entirety is covered by a filter The volume of the inner area is set at from 1×10mmto 16×10mm, the total volume of the bead is set at from 15×10mmto 70×10mm, and the ratio of the total volume of the bead to the volume of the inner area is set at from four to twenty to bring the sensor resistance in CO and that in methane closer to each other and increase the selectivity from hydrogen. |
