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 /spl gamma/-Fe/sub 2/O/sub 3/-TiO/sub 2/ resistive ink. The device electrical resistance decreased from 1 M/spl Omega/ in pure air to 100 k/spl Omega/ in a 2000 ppm butane atmosphere for a working temperature of 300/spl deg/C.
