SC-O2FM2 光纤荧光氧检测模块 应用场景

SC-O2FM2 基于荧光寿命测量技术,传感器尖端涂覆氧敏荧光指示剂(如铂卟啉 / 钌配合物),当蓝光(约450nm)激发后,氧气分子通过碰撞淬灭效应改变荧光寿命,符合 Stern-Volmer 方程:τ₀/τ = 1 + KSV·[O₂],再通过相位调制法精确反演氧浓度。相比荧光强度法,寿命法不受光源波动、光纤弯曲及荧光膜老化影响,长期稳定性与重复性更佳。

模块集成进口高性能荧光膜与自动温度补偿(精度 ±0.1℃),在 0~50℃ 范围内保持高精度测量;同时具备 RS485 与无线双通道输出,Type-C 或 10~24V DC 宽电压供电,可灵活集成到客户设备中作为微量氧监测核心模块,亦可做成单体便携设备独立使用,配合忻成科技安卓/PC 客户端软件完成数据记录与实时监控,广泛适用于生物制药、食品医药包装顶空、发酵与细胞培养、半导体与核电、工业管道及科研实验等微量氧监测场景。

复杂气体环境中的微量氧检测

在化工反应釜、加氢/保护气氛、半导体与电子特气、惰性气体焊接、烟气管道及密闭舱体等多组分气体环境中,混合气常含氢气、氦气、CO、CO₂、NH₃、H₂S、VOC 与高湿水汽,对氧检测构成严峻挑战。SC-O2FM2 基于荧光淬灭原理,对常见共存组分具有极低的交叉灵敏度:H₂、He、CO、CO₂、NH₃、H₂S、VOC 等几乎不干扰氧读数,同时不消耗氧气、不受硫化物"中毒"、无流速与搅动要求,可有效规避电化学与氧化锆传感器在复杂混合气中的交叉偏差,保障测量长期稳定。

针对高湿、含尘、含酸性介质的恶劣气源,SC-O2FM2 可配套冷凝脱水装置、粉尘过滤器、水汽捕集器与 VOC 碳吸附阱等前置预处理模块,并结合选择性透气膜与催化过滤组件阻挡酸性介质与干扰组分接触感应元件,避免探头腐蚀与数值漂移;配合实时温度补偿与软件补偿参数,可在 N₂、Ar、He、CO₂ 等平衡气下实现微量 ppm 级氧含量的长期稳定测量。

  • 多组分抗干扰——H₂、He、CO、CO₂、NH₃、VOC 等共存组分几乎无交叉干扰,适合惰性、可燃与混合气氛工况
  • 宽量程覆盖——常量氧(0~100%)与微量氧(检出限低至 0.03% / 15ppb)无缝衔接,适配保护气氛与微量氧工艺
  • 平衡气适应——支持 N₂/Ar/He/CO₂ 等平衡气下的实时浓度显示与换算
  • 恶劣工况防护——可选冷凝除湿、粉尘过滤、VOC 捕集、耐腐蚀透气膜等前置预处理方案
  • 安全联锁——氧浓度越限报警,联动切断阀自动补氮/补氩,保障化工、半导体等工艺安全
