- Abstract
A novel measurement system for gas sensing materials is designed, and is suitable for sheet shaped or unpacked materials. Except for protecting powder materials during test procedures, this system complements the protection of brittle materials which is increasingly popular. The system has two working modes: multistep elevated temperature and constant temperature control, applied in the pre testing phase of the material and response & recovery characteristics test phase respectively. The two working modes match with different test circuits and could be selected by the software of the system. The temperature control is realized by the combination of conventional PID control and fuzzy PID control, controlling temperature fast and accurately. These features make it a convenient and efficient system for determining the principal performance indexes of a gas sensing material (e.g. optimum operating temperature point, sensitivity, stability, selectivity, response/recovery times, etc.).
