SGDL-5369 Asphalt Concrete Beam Bending Testing Machine

Product Information

The asphalt concrete small beam bending testing machine is a subsystem of our asphalt concrete mechanical performance testing machine. As a universal testing machine for mechanical testing of asphalt concrete, this product has an integrated environmental chamber with a built-in 10 ton axial loading system. It adopts a dual sensor design and optional servo system, which can accurately control any loading rate. By adapting to different software, it can complete common mechanical experiments of asphalt concrete. The redesigned split type control system adopts a high-speed CPU design, with a large screen (240 × 128 dot matrix) LCD Chinese graphic LCD display and analog-to-digital separation design. The high-speed sampling CPU is specifically responsible for data sampling and supports 2 displacement sensor inputs with high accuracy. It also adopts a built-in real-time RTOS and complete testing software functions, which can complete unconventional tests of various materials. The instrument also has a constant temperature box, which can perform low-temperature tests required for certain tests. The instrument automatically maintains a constant temperature with temperature fluctuations of less than 0.3 ℃. This machine comes standard with a 15 inch industrial PC and supports PC control for various experiments.

Product Features:

1.240 × 128 large screen LCD display, numeric keypad, the LCD screen can display complete test data and real-time test curves. Built in embedded real-time OS, modular software design, menu based operation, simple and clear operation, complete functions.

The input channel of the 2.2 channel time-sharing pressure sensor can be configured with different ranges to complete different functional tests.

3. RS232 communication port, with built-in communication protocol consistent with similar products of our company. The upper computer software can be connected to this instrument without modification to complete the start and stop of the test, and read the test result data and test process data.

4. Built in micro printer driver, which can be connected to a micro printer to output test results and simple curve graphs (optional).

5. Built in data storage function, which can save a total of 30 sets of data such as test parameters, test types, test numbers, test results, test curve data streams, etc., and can be directly viewed on the LCD screen.

6. 15 shutdown points can be set for both pressure and displacement, and crushing points and peak values can be detected. Some functions can be turned off through the settings. By selecting the pressure range, setting the recording point, pausing the function, and detecting the crushing point, the majority of material testing requirements can be completed.

7. The instrument automatically controls the temperature, and the target temperature can be set arbitrarily between -25 ℃ and 70 ℃.

8. It can connect to a PC and use the "Asphalt Mixture Testing System Software" to complete experimental operations, calculations, report printing, and other functions. This instrument can operate independently without a PC, but for instruments without a micro printer installed, it cannot print test conclusions. It is recommended to connect to a PC and use powerful PC software to complete experimental operations and data processing, in order to obtain more accurate test conclusions and complete report data.
