產品用途：與鹵酸氣體測試儀同時配合使用，是檢驗電線電纜及光纜低阻燃性電纜評定發煙特性*的專業儀器。
工作原理：
電纜或光纜在特定條件下燃燒的煙密度光測系統由光源、硅光電池接受器和計算機系統組成。光源產生的光通過3m×3m×3m的煙密度實驗室，在光源對面的墻上形成一直徑1.5m±0.1m 的均勻光束，安裝在光束中心處的光電池檢測來自光源的光束強度。當燃燒室內由于燃燒電纜或光纜產生大量煙霧時，煙把光電吸收掉一部分，達到硅光電池的光束強度就減弱，通過計算機系統對數據進行處理，就能夠計算出相對于初始時為100%的具有線性響應的透光率It。
本儀器涉及機械、光學、電子三個方面的專業知識，是機光電一體化產品，具有結構合理、性能穩定、操作簡便等優點；具有WINDOWS XP操作系統、LabVIEW風格界面、完善的安全機制。測試期間實時顯示測量結果并動態地繪出曲線，數據可以*保存、調閱和打印輸出。

Wire and cable smoke density tester
Number: GD201311030069
Specification: DLMD - A
DLMD - A wire and cable smoke density tester
Meet the standards: GB/T17651.1, 17651.2 1998, IEC61034-1 ~ 21, 61034-61034 standard.
Product use: used with halogen acid gas tester at the same time, test wire and cable and optical fiber cable is low flame retardant cable assess smoke characteristics essential professional instrument.
Working principle:
Cable or fiber under certain conditions of combustion smoke density measuring system is 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 of the laboratory, in the wall opposite the light source form a uniform beam diameter 1.5 m + 0.1 m, 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 generate a lot of smoke when burning cable or optical cable, the smoke of photoelectric absorption, achieve the silicon photocell beam intensity is abate, through the computer system for data processing, will be able to calculate the relative to the initial 100% with linear response light transmittance of It.
It involves the mechanical, optical, electronic three aspects of professional knowledge, is the machine products, photoelectric integration has advantages of reasonable structure, stable performance, easy operation; With WINDOWS XP operating system, LabVIEW interface style, perfect security mechanism. During testing real-time display measurement results and dynamically draw perfect curve, the data can be stored permanently and read and print output.
The component of product:
1, building block laboratory (national standard of lab area of 3 m x 3 m x 3 m, this set of system in the laboratory can be adjusted according to the customer's actual area for building blocks, in the laboratory including wind deflector, burning plate, sample holder, circulating fan, precision purifying regulated power supply system, connection system and electric control system, etc.);
2, light source system imported from Germany (nominal light source and silicon optical receiving system);
3, data acquisition, processing and computer automatic control test system;
Product performance indicators:
