~Microcomputer Screen Display Hydraulic Universal Testing Machine WEW-B series

Product description
This series of products are mainly used for metal, non-metallic materials, tensile, compression, bending, shear, peel, tear and other mechanical properties test. The model is a high strength double space frame structure, cylinder using gap seal, spherical bearing support, the next set structure, tension and pressure spacing can be automatically adjusted, hydraulic automatic fixture, set manual control. The control unit is completed by hydraulic system, the test data is collected and analyzed by computer. It can be accessed, and the data and curve can be obtained. The mechanical properties of the materials can be obtained automatically.

Technical specification and scope of use
The products of this series are fully comply with <GB/T2611-2007>, <GB/T16826-2008>, <GB/T228-2002>, <GB/T232-1999> and other standards.
The control system:
A. adopts high precision amplifier and 24 bit high precision A/D converter, effective code + 120000, the test force measurement resolution of 1/120000, the measurement range of continuous measurement range, measurement accuracy of better than 1;
B. The displacement measurement resolution of test machine is 0.0025mm, which is used to measure and control the displacement of the piston;
C. The resolution of the deformation of the test machine is 0.00025mm, which is used to measure and control the deformation of the specimen;
D. in order to manually control the test process, the test data to complete the test data screen;
E. measurement and control system software can work under the WindowsXP/Win7 operating system, using standard database management test data, and provide networking data interface;
F. has the function of test force, peak value, deformation of specimen, displacement of piston, screen display function of test curve, real time display test curve, can choose the coordinates, such as stress, strain, load, load, load, load, time, displacement, time, and so on;
G. can meet the test method of tensile GB/T228-2002< material at room temperature > on the mechanical test and data processing, metal tensile test can automatically calculate the Fel, Feh, Fp, Ft, Fm, Rel, Reh, Rp, Rt, Agt, Z, A, Rm and other parameters, but also on the Fel, Fm etc. artificial recognition, and then print the results. According to the requirements can print different kind of report and curves. Using EXCEL form open, convenient user management; original test record value, report value according to the standard requirements of GB/T228 revision;
The applicable standards and data processing:
A. users can be customized to meet the national standards or other standard data processing software;
B. The test procedure can be used to simulate the re analysis of the data.
