The design of a coke oven gas oxygen content analyzer based on STM32F407 and PM1158

The online analyzer based on STM32F407 for oxygen content in coke oven gas is designed. The analyzer measures oxygen content with digital magnetic and mechanical type oxygen sensor PM1158.It can not only be used to measure the constant oxygen, but also to detect trace oxygen with the characteristics of high measurement accuracy and fast response speed. The output signal of sensor, passing through signal acquisition circuit and conditioning circuit, is sent to microprocessor STM32F407 for subsequent processing. The experimental results show that the coke oven gas oxygen content on-line analyzer can fully meet the needs of industrial field with strong anti-interference ability and good stability.
