常温可燃性气敏元件

NORMAL ATMOSPHERIC TEMPERATURE AND COMBUSTIBLE GAS SENSITIVE DEVICES

以ＳｎＯ２为主体敏感材料，通过掺杂及表面处理等技术，对常温可燃性气敏元件进行了研究。结果表明，对甲烷及异丁烷（３０００ｐｐｍ）的灵敏度＞３，元件初期稳定性、响应及恢复特性好，抗干扰能力强．

SnO2 is the majoy sensing material.By doping and surface-treatment flaming gassenor.the combustible gas sensitive duices.The result prove that the sensitivity tomethane and butane 3000 ppm is more than 3.The sensor has good perlod-stability.The responsive and renewablecharacters are very good.The snsor has good antijampowr.
