产品细节：DSF-2000-MB-UV 2653-213-06 Coen iScan 基于DSP(数字信号处理器)的仪器

iScan2是一种基于DSP(数字信号处理器)的仪器。火焰扫描仪使用固态光学探测器来产生模拟信号。光学探测器在紫外和红外光谱下工作。处理器使用DSP技术来确定是否存在火焰。
火焰扫描仪包含一个自检系统，每20秒测试一次所有关键部件。自检失败将自动切断内部火焰继电器(如果在冗余火焰中配置了继电器)的电源继电器模式)并激活故障继电器(如果配置为独立火焰/故障继电器模式)。

闪烁-闪烁或闪烁频率是指由于燃料的微爆炸而引起的火焰强度的调制。
fport -火焰探测器的响应时间-从火焰强度上升超过用户可调阈值到火焰继电器触点关闭的时间。
FDRT——火焰探测器响应时间——从感觉到火焰消失到发出指示火焰消失的信号之间的一段时间。
MFFRT -边际火焰失效响应时间-从火焰强度低于用户可调阈值到火焰继电器触点打开的时间。
EASI——电子辅助视力指示器——是指位于非危险区域车型背面的红色LED(发光二极管)，它闪烁以指示火焰强度。当没有火焰时，LED大约每秒闪烁1次。当火焰存在时，LED的闪烁频率与火焰强度成正比。在最佳瞄准和扫描仪增益时，LED每秒闪烁约30次。如果LED亮或灭，则扫描仪有故障，不应使用。
DSFComm -这个首字母缩略词代表数字扫描火焰探测器通信软件。
增益-当一个信号被放大时，增益是放大后的信号相对于原始信号的比率。
辨别能力——是区分多重火焰的能力。一个很好的辨别的例子是，当MB扫描仪能够识别与其他燃烧器的主要燃料火焰在背景中的飞行员火焰。
主(背景)火焰的状态不影响检测先导火焰(开或关)的能力。

DSF-2000-MB-UV

The iScan2 is a DSP (digital signal processor) based instrument. The flame scanner uses a solid-state optical detector to generate an analog signal. The optical detector operates in ultraviolet and infrared light spectra. The processor uses DSP techniques to determine if a flame is present.
The flame scanner incorporates a self-check system that tests all critical components every 20 seconds. A selfcheck failure will automatically de-energize the internal flame relay (relays if configured in Redundant Flame
Relay Mode) and energize the fault relay (if configured in the Independent Flame/Fault Relay Mode).

FLICKER – Flicker or Flicker Frequency refers to the modulation of flame intensity due micro-explosions of the fuel.
FDORT – Flame Detector ON Response Time – the period of time from flame intensity rising above the user adjustable threshold to flame relay contacts closed.
FDRT – Flame Detector Response Time –the period of time between the loss of a sensed flame and the signal indicating the absence of flame.
MFFRT – Marginal Flame Fail Response Time – period of time from flame intensity falling below the the user adjustable threshold to the flame relay contacts open.
EASI – Electronically Assisted Sight Indicator – refers to the red LED (Light Emitting Diode) located on the back of the Non-hazardous Area Models, that flashes to indicate flame intensity. When no flame is present the LED blinks approximately 1 time per second. When a flame is present the LED’s blink rate increases proportional to the flame intensity. At optimal sighting and scanner gain, the LED blinks at approximately 30 times per second. If the LED is on solid or off the scanner is faulted and should not be used.
DSFComm – This acronym stands for Digital Scanning Flame-detector Communications software.
GAIN – When a signal is amplified, GAIN is the ratio of the amplified signal relative to the original.
DISCRIMINATION – is the ability to distinguish between multiple flames. An example of good discrimination is when the MB scanner is able to recognize a pilot flame with other burner’s main fuel flame in the background.
The status of the main (background) flame does not affect the ability to detect the pilot flame (ON or OFF).
