  • Abstract
    The paper presents a combustible gas detector mode by thick film technology. Two gold wires were coiled on a cylindrical alumina substrate to form the measuring electrodes. A platinum wire was used to heat the device. The sensitive film was produced by a γ-Fe2 O3-TiO2 resistive ink. The device electrical resistance decreased from 1 MΩ in pure air to 100 kΩ in a 2000 ppm butane atmosphere for a working temperature of 300°C
