85UVF1-1QDK3 火焰检测器

概述：Fireye生产的Phoenix 85UVF/IRF系列火焰检测器是应用了固态火焰检测传感器的微处理器设备。它设有一个可以自动设定ON/OFF （有火/无火）门槛值的内部继电器，因此可以取消远程放大器或者火焰开关。

Phoenix火检探头检测目标火焰产生的调制振幅（即火焰闪烁特性），以检测宽广的频率。在探头的设定程序中，目标火焰的振幅将会与最佳的ON/OFF值一起被自动储存。相应适合的传感器增益也将被自动选取。探头兼有全部自诊断和电子自检功能。

Phoenix 85UVF/IRF因为检测元件和适用危险区不同级别的认证不同而分成多种型号Phoenix 85UVF/IRF火焰探头需24Vdc供电，通过8针电气快拆接头与电缆连接（QD型号）。还有标准4-20mA火焰强度信号输出。

注意: QD型号的接线形式改为电气快拆接头连接，替代了原有的自带3米长电缆的探头型号。
QD探头（相应电缆型号为59-546-X）可直接应用于Class I Division 2危险区。因而取消了“EX”型号，应用于Ex II 2 G/D 类危险区的“CEX”型号保留不变。

应用：Phoenix 85UVF 自检探头可检测295-340nm波长的紫外线。Phoenix 85UVF1-1QDK3和85UVF1-1CEXK3火检探头是标准的Phoenix产品的衍生，使用先进的光学滤镜。该滤镜调节了光学灵敏度，可探测310nm到500nm波长的可见光。

Overview: Fireye’s Phoenix 85UVF/IRF series flame detectors are microprocessor devices with solid-state flame detection sensors. It has an internal relay that automatically sets the ON/OFF (fire/no fire) threshold, so remote amplifiers or flame switches can be cancelled.

The Phoenix fire detector detects the modulated amplitude (i.e. flame flicker characteristics) generated by the target flame to detect a wide range of frequencies. The amplitude of the target flame is automatically stored along with the optimal ON/OFF value during the probe setup program. The appropriate sensor gain will also be selected automatically. The probe has full self-diagnostic and electronic self-test functions.

The Phoenix 85UVF/IRF is divided into various models due to different levels of certification for different detection components and applicable danger zones. The Phoenix 85UVF/IRF flame probe requires a 24Vdc power supply and is connected to a cable via an 8-pin electrical quick-release connector (QD model). There is also a standard 4-20mA flame intensity signal output.

Note: The QD model has an electrical quick-release connection instead of the original probe model with a 3-meter cable.
The QD probe (corresponding cable model 59-546-X) can be directly applied to Class I Division 2 danger areas. The “EX” model was therefore eliminated and the “CEX” model for use in the Ex II 2 G/D danger zone remained unchanged.

Application: The Phoenix 85UVF self-test probe can detect ultraviolet light at 295-340nm wavelengths. The Phoenix 85UVF1-1QDK3 and 85UVF1-1CEXK3 fire detectors are derivatives of the standard Phoenix products and use advanced optical filters. The filter adjusts the optical sensitivity to detect visible light at wavelengths from 310nm to 500nm.
