Research of oxygen concentration and temperature detection system
-
摘要: 针对现有煤矿火灾探测技术存在的响应时间长、精度低、可靠性差等问题,基于可调谐激光光谱吸收检测技术,设计了一套氧气浓度和温度检测系统,并在实验室环境下对该系统进行了测试,结果表明,在0~100.0%氧气浓度范围内,系统测量误差小于1%;在253~1 000 K气体温度范围内,系统测量误差小于2%。Abstract: For problems that long response time, low precision and poor reliability of existing coal mine fire monitoring technologies, a oxygen concentration and temperature detection system was designed based on tunable laser absorption spectroscopy detecting technology. The system has been tested in laboratory. The test results show that the measurement error of the system is less than 1% when oxygen concentration is 0-100.0%, and the one is less than 2% when gas temperature is 253-1 000 K.
