Touch Screen Computer Dual Control Building Materials Smoke Density Tester

ASTM D2843 Touch Screen Computer Dual Control Burning Smoke Density Tester

Application

The touch screen computer dual-control smoke density tester for building materials is developed according to the technical conditions specified in the national standard GB/T8627-2007 "Smoke Density Test Method for the Burning or Decomposition of Building Materials". It is suitable for static burning of building materials and their products and other materials. Determination of smoke production.

Features

• Double control mode, you can control the operation on the touch screen or on the computer, the operation mode can be easily switched! (Users bring their own computer, printer; PC software, router, network cable we will send out with the device)
• One device can be operated by several computers at the same time, and several computers can be online at the same time, which can realize LAN sharing!
• The main and auxiliary burners can be automatically rotated and the positioning is accurate.
• Self-developed control programs can satisfy various operations, records, time-to-time curves, and result calculations in the test.

Technical parameters

1. For the maximum smoke density (MSD) and smoke density grade (SDR) of the test piece: 0-100% continuously measurable and automatically calculated;

2. Use standard filter to correct the error not more than 3%; each device is equipped with three standard filters, and the data of light source calibration is representative

3. Bunsen burner working pressure (210±5) KPa;

4. The Bunsen burner applies flame to the sample for 4 minutes;

5. Combustion lamp: Bunsen burner, length 260mm, nozzle diameter 0.13mm, 45° angle with smoke box;

6. Photoelectric system: the light source is a bulb, the power is 15W, and the working voltage is 6V;

7. Exhaust system: The machine is equipped with a powerful exhaust fan, after the test, the exhaust gas can be exhausted outdoors;

8. Smoke density measurement range: 0~100%;

9. Smoke density measurement accuracy: ±3%;

10. Receiver: It is a silicon photovoltaic cell, with a light transmittance of 0% for no light to pass, and a light transmittance of 100% for light to pass through without obstruction;

11. The working pressure of the main burner: 276KPa (adjustable);(Optional auxiliary burner)

12 Automatic timing, automatic ignition, automatic smoke exhaust; the luminous flux can be linearly corrected and tested in stages, which improves the accuracy of the data;

13. Touch screen:

①　Size: 5 inches, the effective display size is 11cm long and 6.28cm wide;

②　Resolution: 800*480

③　Communication interface RS232, 3.3V CMOS or TTL, serial port

④　Storage capacity: 1G

⑤　Using pure hardware FPGA to drive the display, "zero" startup time, and it can run after power-on

⑥　M3+FPGA architecture is adopted, M3 is responsible for instruction analysis, FPGA focuses on TFT display, and the main controller adopts low-energy processors and automatically enters energy-saving mode

14. Gas source: 95% propane gas, or coal gas of the same purity (Note: the gas source and link head are provided by the user);

15. Length * width * height 740 * 500 * height 900 (mm)

Working Environment

Structure

Divided into two parts: smoke box and control;

Smoke box part: On the left and right side panels of the smoke box, there are power switches, safety signs switches (backlight switches), gas regulators, and switches for controlling exhaust fans (fan switches).
