measurement,
2、適用范圍:Scope of application:
用來(lái)測(cè)定電纜和光纜在特定條件下燃燒時(shí)釋出煙的濃度
Used for determination of cable and cable released under certain conditions when burning smoke concentration
3、主要性能參數(shù)：The main performance parameters:
1、本儀器涉及機(jī)械、光學(xué)、電子三個(gè)方面的專業(yè)知識(shí)，是機(jī)光電一體化產(chǎn)品，具有結(jié)構(gòu)合理、性能穩(wěn)定、操作簡(jiǎn)便等優(yōu)
點(diǎn)；WINDOWS XP操作界面、LabVIEW風(fēng)格、完善的安全機(jī)制。測(cè)試期間實(shí)時(shí)顯示測(cè)量結(jié)果并動(dòng)態(tài)地繪出曲線，數(shù)據(jù)可以永
久保存、調(diào)閱和打印輸出,可直接打印報(bào)表。
2、 電纜或光纜在特定條件下燃燒的煙密度光測(cè)系統(tǒng)由光源、硅光電池接受器和計(jì)算機(jī)系統(tǒng)組成。光源產(chǎn)生的光通過(guò)3m×
3m×3m的煙密度實(shí)驗(yàn)室，在光源對(duì)面的墻上形成一均勻光束，安裝在光束中心處的光電池檢測(cè)來(lái)自光源的光束強(qiáng)度。當(dāng)燃燒室
內(nèi)由于燃燒電纜或光纜產(chǎn)生大量煙霧時(shí)，煙把光電吸收掉一部分，達(dá)到硅光電池的光束強(qiáng)度就減弱，通過(guò)計(jì)算機(jī)系統(tǒng)對(duì)數(shù)據(jù)進(jìn)
行處理，就能夠計(jì)算出相對(duì)于初始時(shí)為的具有線性響應(yīng)的透光率It。
3、光源：進(jìn)口石英鹵素?zé)?，?biāo)稱光返量：2000～3000Lm
4、接受器：光譜響應(yīng)與照明委員長(zhǎng)（CIE）的測(cè)光儀相匹配。
5、透光率0%為無(wú)光線通過(guò)，透光率光無(wú)遮擋完全通過(guò)。
6、標(biāo)準(zhǔn)火源：為1.0L酒精配置：乙醇90%、甲醇4%、水6%
7、利用臺(tái)式風(fēng)扇使煙在燃燒室里均勻分布。風(fēng)扇轉(zhuǎn)軸距離地面高度250mm,具墻500mm,風(fēng)量7立方米每分鐘。試驗(yàn)期間空氣
由風(fēng)扇作水平吹動(dòng)。
1, it involves the mechanical, optical, electronic three aspects of professional knowledge, is a photoelectric
integration products, with reasonable structure, stable performance, easy operation, etc
Point; WINDOWS XP operating interface, LabVIEW style, perfect security mechanism. During testing real-time
display measurement results and dynamically draw perfect curve, the data can be everlasting
For a long time to save and read and print output, can be directly printed statements.
2, cable or optical cable under certain conditions of combustion smoke density optical measurement system
composed of light source, silicon photocell of receiver and the computer system. Light source of light by 3 m
x
3 m x 3 m smoke density lab, form a uniform light beam in the wall opposite the light source, the installation
of the photocell detection in the center of the beam intensity of light from a light source. When the
combustion chamber
Due to combustion within the cable or optical cable to produce a large amount of smoke, the smoke of
photoelectric absorption, achieve the silicon photocell beam intensity is abate, through the data into the
computer system
Line processing, will be able to calculate the relative to the initial with linear response light
transmittance of It.
3, light source: imported quartz halogen lamp, nominal return amount of light: 2000 ~ 3000 lm
4, receiver: chairman of the spectral response and international lighting (CIE) match the photometer.
5, 0% light transmittance through light, light transmittance light shining through.
6, standard fire: 1.0 L configuration: alcohol 90%, water 6% 90% ethanol, methanol
7, use desktop fan to make smoke uniform distribution in the combustion chamber. Fan shaft height distance 250
mm, 500 mm wall, air volume 7 cubic meters per minute. During the test air
Level blown by the fan.
