| Abstract: | A group of optimum design of measuring circuit for gas sensor has been investi-gated in this paper. Linear step-up voltage heating power'resistance output ratio amplifier pho-to-phonon display and auto-return zero curcuit are included in measuring circuit. The VH-Rg continuous curves and precise values of sensitivity and selectivity of gas sensing elements have been given. |
