Product Description

Product Description

IEC 61034 Smoke Density Measuring Device for Cable Optical Cable Smoke Concentration Chamber
1. Introduction
In accordance with GB/T17651.1~2, IEC61034-1~2 "cable or optical cable burning under specific conditions of smoke density determination" part 1 "test equipment" and part 2 "test procedures and requirements". The measurement of smoke density is an important aspect to evaluate the combustion characteristics of cable or optical cable, which is related to the evacuation of personnel and the determination of whether close to fire extinguishing. This instrument is mainly used to determine the smoke concentration of the cable and optical cable when burning under specific conditions, and to verify the smoke density. In the flame combustion or flameless combustion conditions, transmittance is used as a comparison of different cables or optical cable under specific conditions of a determination.

2. Features
The instrument involves mechanical, optical, electronic three aspects of professional knowledge, is the integration of mechanical and electrical products, has the advantages of reasonable structure, stable performance, easy operation; Windows XP operation interface, LabVIEW style, perfect security mechanism. During the test, the measurement results can be displayed in real time and the perfect curve can be drawn dynamically (displaying the transmission rate and time curve). The data can be permanently saved, read and printed out, and the report can be printed directly.
Measurement software: it is in Windows XP+VB6.0 operation interface, can test the main data smoke optical density, specific optical density, smoke generation rate, maximum smoke generation rate, average smoke density, etc.Also has the calibration, editing, testing, parameter adjustment and other operation interface. The program adopts computer automatic control, collection, record and result settlement.

3. Principle
The smoke density light measurement system for cable or optical cable burning under specific conditions consists of a light source, a silicon photocell, a light source receiver and a computer system. The light generated by the light source passes through the smoke density laboratory of 3m×3m×3m, and forms a uniform beam with a diameter of 1.5m±0.1m on the wall opposite the light source. A photocell installed at the center of the beam detects the intensity of the beam from the light source. When a large amount of smoke is generated in the combustion chamber due to the burning cable or optical cable, the smoke absorbs part of the photoelectricity, and the beam intensity of the silicon photocell is weakened. By processing the data through the computer system, It can be calculated that the transmittance with linear response is 100% relative to the initial transmittance.
Three, the design of the combustion chamber, take two ways for customers to choose: the first kind of brick wall, our company to promote the design scheme, send professional engineers on-site construction guidance; The second is fixed on an Angle iron bracket with a suitable material and constitutes the entire cubic combustion chamber.
