摘要
本文对金属氧化物半导体气敏传感器和CD212气敏传感器的性能作了分析和比较,并介绍了适用于瓦斯气、液化石油气等可燃气体的贮气仓库使用的JTFB—93防爆型可燃气体泄漏报警器的设计思想、电路结构、工作原理、主要技术指标、调试和使用方法。
This paper gives an analysis and comparison of the natures between metal oxide semi-conductor gas sensors and CD212 gas sensors. It also tells about the design, circuit configu-rations, operafing principles, main technical qualifications, shakedown tests and usage modes of the JTFB-93 Explosion Protection Type Combustible Gas Leakage Sirens, which can be used in warehouses storing clmbustible gases, such as methane gas and liquefied petroleum gas.
