BFI火焰检测器CFC2000IR2L产品简介
各光谱范围内的积分方法用于紧凑型火焰控制器的火焰辐射分析。
在预放大之后，从输出信号中提取不需要的恒定光部分。随后的灵敏度调节允许信号抑制以适应相应的燃烧器条件。
随后连接的带通滤波器实现了仅评估主燃烧区的典型火焰辐射的调制，并且来自相邻燃烧器的外部光信号可以与单个燃烧器区分开。
其他功能组集成了动态监控通道的信号处理功能，通过暗相监控，持续检查设备的故障安全性。
元件缺陷导致火焰继电器立即关闭，火焰继电器可作为无电位转换触点使用。
开关状态“火焰开启”由设备背面的黄色LED显示，就像火焰的强度一样，由闪烁的绿色LED显示。
火焰强度输出0（4）- 20 mA可用于外部显示器。
安全关闭时间始终取决于要检测的燃料，出厂时调整为1秒。更长的关闭时间可选的本地规格。
The integral method in the respective spectral range is used for the flame radiation analysis of the compact flame controller.
After pre amplification, the unwanted portion of constant light is withdrawn from the output signal. The subsequent sensitivity adjustment permits signal suppression for the adaptation to the respective burner condition.
The subsequently connected band pass filter achieves that modulation of the typical flame radiation of the primary combustion zone is evaluated only, and outside light signals from neighbouring burners can be differentiated from the individual burner.
The further functional groups integrate the signal processing for the dynamic monitoring channel, which by means of a dark-phase monitoring, continuously checks the failure-safety of the unit.
A component defect leads to an immediate switch-off of the flame-relay, which is available as a potential-free changeover contact.
The switching state flame on is displayed by a yellow LED on the rear side of the unit, just as the intensity of flame, which is displayed by a flashing green LED.
A flame intensity output 0(4) - 20 mA can be used for external displays.
The safety switch-off time, which always depends on the fuels to be detected, is factory adjusted to 1 second. Longer switch-off times in acc. to local specifications available as option.
