液体干燥低氮氧化物应用，以及具有显著水平的水和蒸汽的应用注入后，盖革米勒管火焰探测器探测到的紫外光被雾吸收燃料、蒸汽或水。通用电气的研究中心发明了一种碳化硅(SiC)光电二极管对火焰产生的紫外线波长较长的成分更敏感。

这个时间波长的光确实能很好地穿透油雾，因此基于碳化硅的传感器是显著的对火焰的存在更敏感。通用电气正在生产一种利用碳化硅光电二极管的火焰传感器并已成功地在通用电气的多个燃气轮机装置上运行。

传感器有一个透明的蓝宝石窗口耐紫外光，能承受压缩机排气温度和压力。里面有一个透镜将光聚焦在密封封装中的碳化硅光电二极管上。光电二极管被连接到aMOSFET输入放大器。放大器具有较高的初始增益，可自动转换为较低的增益

Liquid dry low nitrogen oxide applications, as well as applications with significant levels of water and steam After injection, the UV light detected by the Geiger-Miller tube flame detector is absorbed by the fog of fuel, steam or water. Ge's research center has invented a silicon carbide (SiC) photodiode that is more sensitive to the longer wavelengths of ultraviolet light produced by flames.

Light at this time wavelength does penetrate the oil mist well, so a silicon carbon-based sensor is significantly more sensitive to the presence of flame. Ge is producing a flame sensor that utilizes a silicon carbide photodiode and has been successfully operated on multiple GE gas turbine installations.

The sensor has a transparent sapphire window that is resistant to ultraviolet light and can withstand compressor exhaust temperature and pressure. Inside is a lens that focuses light on a silicon carbide photodiode in a sealed package. The photodiode is connected to the aMOSFET input amplifier. The amplifier has a high initial gain that is automatically converted to a lower gain
