Product Description
Wire and Cable Smoke Density Test Chamber
Product Description
Comply with GB/T17651.1~2, IEC61034-1~2. The determination of smoke density is an important aspect of assessing the burning characteristics of cables or optical cables, which is related to the evacuation of personnel and the ability to approach the determination of fire fighting.This instrument is mainly used to determine the concentration of smoke released when the cable and optical cable are burned under specific conditions, and to verify the density of smoke produced. Under flame burning or flameless burning conditions, light transmittance is used as a way to compare different cables or optical cables under specific conditions.
Features
This instrument involves professional knowledge in three aspects of machinery, optics, and electronics. It is an electromechanical integration product with reasonable structure, stable performance, and easy operation. WINDOWS XP operating interface, LabVIEW style, and perfect security mechanism. During the test, the measurement results are displayed in real time and the perfect curve is dynamically drawn (displaying the transmittance and time curve). The data can be permanently saved, read and printed out, and the report can be printed directly.
Principle
The smoke density optical measurement system of the cable or optical cable burning under specific conditions is composed 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 3 × 3 × 3(m) to form a uniform beam with a diameter of 1.5m±0.1m on the wall opposite the light source. The 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 burning cables or optical cables, the smoke absorbs a part of the photoelectricity, and the intensity of the beam reaching the silicon photovoltaic cell is weakened. By processing the data through the computer system, it can be calculated that it is 100% relative to the initial Linear response light transmittance.
Composition
The entire instrument consists of closed test chamber, photometric measuring system, alcohol tray, combustion system, igniter, test box, cable holder, temperature measuring instrument and smoke density testing software. The circuit is developed by single chip microcomputer, with high technical content and stable performance. This instrument is suitable for all cables and is widely used by the production factories of wire and cable industry as well as scientific research and testing departments. The test box is a test cube with a volume of 27m3.
