摘要
激光式可燃气体探测器基于光谱吸收原理,利用可燃气体对特定波长的探测激光的吸收效应,判断目标区域内是否发生了可燃气体泄漏,并通过计算探测激光被吸收的强弱,分析、判断目标区域内可燃气体的泄漏量,解决了管道阀门、法兰等部位长期存在的微泄漏无法量化监测的难题。超前预警、可视化监测功能,满足了天然气站场天然气泄漏监测的要求。
Based on the principle of spectral absorption, the laser combustible gas detector uses the absorption effect of combustible gas on the detection laser of a specific wavelength to determine whether there is a combustible gas leakage in the target area. By calculating the strength of the absorption of the detection laser, the leakage of combustible gas in the target area is analyzed and judged. The problem that the long-standing micro-leakage of pipeline valves, flanges and other parts cannot be quantitatively monitored is solved. Advance warning and visual monitoring functions meet the requirements of natural gas leakage monitoring in natural gas stations.
