WES-B Series Microcomputer-Controlled Electro-Hydraulic Servo Universal Material Testing Machine

Description

Product Introduction:

The WES‑B series micro‑electrohydraulic servo‑controlled universal materials testing machine employs a hydraulic power source, electro‑hydraulic servo control technology, and computer‑based data acquisition and processing. It is a high‑precision testing instrument capable of closed‑loop control and automated testing. The system comprises four main components: the testing frame, the oil supply unit (hydraulic power source), the measurement and control system, and the test fixtures. Its maximum test force is 2000 kN, and its accuracy class exceeds Grade 1.

The WES‑B series micro‑electromechanical hydraulic servo‑controlled universal materials testing machine meets the standard test requirements specified for metallic tensile testing, and can also perform tensile, compressive, bending, shear, and other types of tests on various materials and products in accordance with other standards. It is capable of determining key material properties such as tensile strength and yield strength.

This testing machine and its accessories comply with the requirements of GB/T 228, GB/T 2611, and GB/T 3159.
