西德 Valvo 公司生产的型号为82040262001的半导体气敏元件是一个毫米级的陶瓷小丸,烧结上二条铂丝。在温度升高的情况下,当某一特定气体的浓度改变时,其电阻值也发生变化。元件安装在一个圆柱形金属栅网罩内。当空气中某种有害气体(如
West Germany Valvo company’s model 82040262001 semiconductor gas sensor is a millimeter-sized ceramic pellets, sintered on two platinum wire. In the case of an increase in temperature, the resistance of a particular gas also changes as the concentration of a particular gas changes. The components are mounted in a cylindrical metal grille. When the air some kind of harmful gas (such as
