Automatic asphalt mixture Wheel-Track Tester

 (touch screen single-channel scientific research type)

Model: HYCZ-5

The asphalt mixture road rutting tester not only supports the original 0.7MPa standard road rutting test, but also can complete the 1.4MPa heavy-duty traffic road rutting test by adding optional accessories. At the same time, it can also complete some non-standard tests, and the adaptation range is greatly improved. . Applicable standards: JTGE20-2011/T0719-2011.

Improvement points

The instrument's control system uses the latest kernel high-speed ARM microprocessor, embedded real-time OS, full-featured software, 7-inch full-color touch display, full Chinese display, whether it is debugging or testing, easy to learn.

The instrument can be connected to the host computer for testing, or it can be run independently from the computer and complete the relevant test functions. When the PC is not connected, all tests of a single test wheel can be performed, including temperature control, test, storage, printing, and graph display. However, these functions can only provide users with basic needs, display information, interface friendliness, graph accuracy, etc. can not be compared with PC software.

When the instrument is separated from the PC test, a completely independent control system is adopted, and the test data is stored in the internal memory of the controller, and can only be inquired and printed on the controller interface, and cannot be uploaded to the PC.

main feature

1. Automatic temperature control system with air circulation, internal with constant temperature water tank, can be used for water immersion test. The heating of the cabinet adopts a constant temperature PTC heating unit, which is more safe and reliable. The temperature of the air stream heated by heating is limited to the maximum, the flow rate is increased, and the temperature uniformity inside the cabinet is at least 50% higher than that of the old model.

2. The improved universal crank connection mechanism transmits more power and has less noise. Due to the improved transmission mechanism, the force of the connecting member is reduced, and the life of the moving member is greatly improved.

3, the internal components are all treated with stainless steel infiltration process, beautiful and not rust.

4, additional load, can be used for heavy traffic rutting test.

5, 7-inch color touch screen, friendly and beautiful interface, test real-time curve, test status at a glance.

6, you can enter the test number and test mode, the data is automatically stored and printed. Has 100 sets of tests and storage capacity for curve data.

7. With USB host interface, internal test data and device sensor calibration information can be backed up and exported or imported using U disk, directly supporting EXCEL format file (including test information, test results and graph data) named by storage number.
