LWD-5A Marshall Stability Tester

Product Information

The LWD- Marshall Stability Tester adopts an integrated design, with the main unit and control system integrated together. The installation and connection are simple, and it has the ability to load and measure axial loads up to 50KN, as well as measure vertical deformation. It is used for measuring the stability and flow value of specimens with a size of Φ 101.6mm in Marshall tests. At the same time, the main unit of this testing instrument only needs to be modified slightly and equipped with relevant accessories to complete various tests that require the application of vertical loads.

Product Features:

1. It can achieve automatic loading, automatic shutdown, data display, data acquisition, peak discrimination, and peak maintenance.

2. Built in origin correction algorithm that meets regulatory requirements, automatically eliminates initial nonlinear deformation errors of the specimen. The slope of the corrected straight line can be adjusted. ⊙ Industrial grade board design, high-precision and high-speed sampling, precise capture of loading curve feature points.

3. Adopting dual self-protection functions of hardware and software to ensure the safety and reliability of the experimental process.

4. The modular design concept is applied, and each functional module is relatively independent, making it easy to repair and maintain.

5. Equipped with manual knob and electrically adjustable loading function.

6. Display screen: 10.1-inch touch screen.

7. Equipped with data storage and curve display functions.

8. Large capacity data storage and high-resolution curve storage.

9. Patent fragmentation point optimization algorithm.

10. High torque stepper motor with software speed closed-loop control and noise free design.

11. Equipped with both master and slave U ports, test data can be exported using a U drive.

12. Standard PC version testing software with comprehensive testing and reporting functions, capable of exporting high-precision curve data.

13. Equipped with communication interface, optional networking PC software or networking communication protocol version.
