Microcomputer-controlled constant stress pressure tester (YAW-2000)

Microcomputer-controlled constant stress pressure tester (YAW-2000)

Product Classification： Fully automatic pressure tester
Product Overview：This series of products is mainly used for mechanical properties tests of concrete, high-strength concrete, cement components and other materials. This series of products adopts a computer to fully automatic control of the test process, uses an electro-hydraulic servo system to control the loading, and an electric lead screw to adjust the test space, and has automatic and manual loading functions.

1. Functional uses of microcomputer-controlled constant stress pressure tester (YAW-2000):

This machine is an important instrument and equipment for testing the physical properties, structural properties and internal and external defects of various concrete materials and their products. Tests on compression types of metal or non-metallic materials can be realized, performance indicators such as compressive strength of the measured material can be automatically obtained, and closed-loop controls such as equal rate loading, equal rate deformation, equal rate displacement, and equal rate strain can be completed.

This machine is accurate in testing, powerful in functions, convenient in operation, stable and reliable. Widely applicable to universities, research institutes, testing institutions, aerospace, military industry, metallurgy, machinery manufacturing, transportation construction, construction and building materials and other industries to conduct precise material research, material analysis, material development and quality control. Process qualification performance verification tests for materials or products can be carried out.
