Independent structure design of the operation controller, with the microcontroller as the control core, together with a large-screen (800*480 dot matrix) color touch screen, which can be wired, remotely operated, and can also be moved and wirelessly operated.
It adopts variable frequency motor to control the tensile speed of the bitumen specimen, the photoelectric pulse to detect the tensile speed, and the frequency converter to automatically adjust the speed, and the two tension sensors independently test the tensile value and display the tensile value via display screen.
With 50L split tank design, separate water tanks independently complete the refrigerating, heating and constant temperature control of circulating water. It equipped with digital temperature sensor to measure temperature.
The double-sink design ensures that the test time is constant at ±0.1°C, and there is no fluctuation in the water surface of the tank during the tensile test. The temperature is constant. After the test is completed, it will automatically reset and work again.
Stretching system adopts external screw rod, double track positioning; drive motor adopts variable frequency motor, large torque range, wide selection range, stable and reliable work.
With automatic operation mode and manual adjustment mode, users can select [Automatic operation] or [Manual adjustment machine], making the operation and maintenance of the instrument very convenient and easy.
The Bitumen Ductility Testing Machine is designed with two-way force measuring devices. One test can achieve three specimens of ductility and two specimens tensile test.
