摘要
设计了一种甲烷测量装置。该装置采用锯齿波调制的DFB激光器作为检测光源,利用光谱吸收的原理,实现对甲烷浓度的实时检测等功能。具有测量精度高,抗干扰能力强,使用寿命长等特点。本文首次报告了光纤瓦斯检测装置在煤矿瓦斯抽采监测方面的现场监测结果。
This paper presents a fiber methane detection device , which is based on a DFB laser diode and a fiber optic probe, whose spectral selection is near infrared spectroscopy. The device is of high precision, immunity to humidity and a long life span. This paper originally reports the situation test results of its application in the surveillance of methane extraction.
