R2868日本HAMAMATSU公司生产的火焰传感器和传感器应用电路板。
我司是日本HAMAMATSU公司中国区域一级代理商主营紫外线照度计专用紫外线传感器G5842,火灾报警装置用火焰传感器R2868配套消防器材厂商,现货供应日本HAMAMATSU公司R2868火焰传感器C3704探测模块,R2868称为火焰发现者.在火星产生瞬间能够准确地发现,
并且对非可见光的高传输的电晕现象可以完全解除.Hamamatsu R2868 是利用紫外线 TRON
通过金属的光电效果和瓦斯乘法效果来发现火星源. 它可以探测 185 到
260个不同的狭窄光谱敏感源.它对可见光完全没有感应,也不需要过滤器任何可见光(不像半导体探测器).
它具有很小的体积和很宽敏感角度(择向性),并能快速准确地发现从火焰被发出的弱紫外线.(能够探测 5 m 或在稍远处发现香烟点大小的火焰.)
Compact UV
Sensor with High Sensitivity and Wide Directivity,
Suitable for
Flame Detectors and Fire Alarms. Hamamatsu
R2868 is a UV TRON ultraviolet detector that makes
use of
the photoelectric effect of metal and the gas multiplication
effect.
It has a narrow spectral sensitivity of 185 to 260 nm, being
completely insensitive to visible light. Unlike semiconductor
detectors, it does not require optical visible-cut filters, thus
making
it easy to use. In spite of
its small size, the R2868 has wide angular sensitivity
(directivity) and can reliably and quickly detect weak ultraviolet
radiations emitted from flame due to use of the metal plate
cathode
(eg. it can detect the flame of a cigarette lighter at a
distance of more than 5 m.).
The R2868 is
well suited for use in flame detectors and fire
alarms,
and also in detection of invisible discharge phenomena
such as
corona discharge of high-voltage transmission lines.
