GWE-300 Microcomputer Display Strand Wire Testing Machine is mainly used for the tensile experiment of the strand wire. It can also implement the experiments such as the tensile, compression, bending, cutting etc,to the metal and non-metallic, composite materials. It adopts the four vertical columns framework structure with the more stable structure and the more guaranteed rigidity, It employs the hydraulic chuck sample automatic clamping and sputter film pressure sensor with the higher measuring accuracy and the wider range . GWE series also utilizes the high precision shift sensor to measure the displacement. It adopts the high accuracy drawing meter to measure the sample deformation. It uses PCI bus control mode and Windows XP operation system .It can be allocated with touch screen which is more beneficial for the operation and control of the tester .It can partially amplify the experimental curves and hold the additive comparison to the multiple curves. It can automatically seek the multiple technical parameters such as elastic module E, upper yield strength Rah, lower yield strength R_el, tensile strength R_m , stipulated non-proportional extension force Fp0.2,max force extensibility A_gt ,max force Fm and so on . It can print the complete experimental report and curves. It comprehensively conforms with GB/T228-2002 and GB/T5224-2003 requirements.
