| Abstract: | Based on the basic principle of sensors with supporter filled element that measures the methane concentration, a method for designing Weston bridge by using the sensor and the reference element is proposed and the mathematical model of the automatic temperature control and the measurement of methane concentration is developed. The measurement results show that this design expands the measuring range, reduces burning-knot and vaporization of catalyst and extends the service life of the supporter catalyst filled element. |
