Fireye火焰检测器45RM4系列 
Fireye火焰检测器45RM4系列 是自检火焰传感装置。 它们由透镜，光电探测器和固态频率调谐电路组成，包含在压铸铝外壳中。

当通过兼容的自检Fireye火焰安全控制装置供电时，扫描仪会检测是否存在具有某些特性的火焰。

45RM4有一个16位旋转选择器，用于选择理想的火焰“闪烁”频率。 这对于检测和区分低频排放占主导地位的装置（煤粉，低氧等）以及中频应用（天然气）的火焰开启和火焰关闭条件非常有效。 这使得45RM4型扫描仪可以区分目标火焰和背景火焰，适用于各种应用和燃料。
45RM4 Series Scanner
The Fireye® Type 45RM4 flame scanners are self-checking, flame sensing devices. They consist of a lens, photodetector, and a solid-state, frequency tuned circuit contained in a die-cast aluminum housing.

When powered by a compatible, self-checking Fireye flame safeguard control, the scanner detects the presence and absence of flames having certain characteristics.

The 45RM4 has a 16-position rotary selector to select the ideal flame “flicker” frequency. This is effective in detecting and discriminating Flame ON and Flame OFF conditions on installations where low frequency emissions predominate (pulverized coal, lo-nox, etc.), as well as mid-range frequency applications (natural gas). This allows type 45RM4 scanners to discriminate between the targeted flame and background flame for a wide range of applications and fuels.
