● It adopts high sealing one-way/two-way cylinder, which is highly efficient and durable.
● The host structural parts are made of high-strength iron plates, making the whole machine rigid and stable.
● The force measuring element is a high-precision oil pressure digital sensor. The sensor has high accuracy, good repeatability and long-term stability.
● The electrical signals emitted when the force is applied are collected and processed by computer software.
● The oil source system adopts servo closed-loop control, equipped with digital servo valves, motors with stable torque and speed, high-precision valves and other components, with fast response and high sensitivity.
● The system monitors parameters such as load and deformation in real time, has features such as tracking, follow-up, and adjustability, and can achieve fully automatic and precise control.
● The measurement and control system uses a high-speed Ethernet communication interface to communicate with the computer.
● Test data is managed using a standard database and can be accessed at will. It can realize re-analysis of test data and curves, partial amplification and data re-editing. It can automatically calculate various mechanical performance indicators of materials, print out complete test reports and curves.
● Equipped with force overload protection, force channel overspeed protection, range limit protection, etc.
● The measurement and control system can be programmed by users according to test needs, such as cyclic loading, test force maintenance, etc.
