Forney 福尼火检探头 IDD-II

通常用于感应重质燃油和煤的火焰。IDD-IU（未过滤）火焰探测器通常用于探测轻质燃油火焰。ID-IL（褐煤）火焰探测器专门设计用于感应褐煤和高灰煤火焰产生的低火焰频率。

IDD-II系列与福尼的支持放大器IDD-9000配合使用。（DR-6101E、RM-IDD和ID-IIA现已过时，取而代之的是IDD9000放大器）。

当感应到火焰时，IDD-II的固态电路会放大硫化铅传感器发出的连续变化的电压信号。信号通过四芯电缆发送到放大器。放大器处理信号并向燃烧器管理系统提供输出。为了无故障运行，探测器电子设备封装在铸钢外壳内。此外，放大器还启动传感器和印刷电路板的定期电子自检，以验证检测器组件的正确操作。

The IDD-II (Filtered) flame detector is typically used for sensing heavy fuel oil and coal flames. The IDD-IIU (Unfiltered) flame detector is typically used forsensing light fuel oil flames. The ID-IL (Lignite) flame detector is specifically designed to sense low flame frequency produced by lignite and high ash coalflames.

The IDD-II Series is used in conjunction with Forney' s supporting amplifier the IDD-9000. (The DR-6101E, RM-IDD and ID-IIA are now obsolete - replacedwith the IDD9000 Amplifiers).

The IDD-II' s solid state circuitry amplifies a continuously changing voltage signal transmitted from the lead sulfide sensor when flame is sensed. The signal isthen sent to the amplifier by way of a four conductor cable. The amplifier processes the signal and provides outputs to the burner management system.

For trouble-free operation, the detector electronics are potted within the cast steel housing. In addition, the amplifier also initiates a periodic, electronicselfcheck of the sensor and printed circuit board to verify proper operation of the detector assembly.
