Ⅰ、Main functions
WDW series are suitable for tensile, compression, bending
cutting,shearing and tearing test of rubber, plastic, electrical
wire and cable, composite, plastic profiled bar, waterproof roll,
etc. They may add test metheds or rules according to
customers’requirement .They are essential testing instrument for
quality testing section, university and college, research
institution and industrial and mining enterprise.
Ⅱ、Product features
This machine equips alternating servo motor for driving crosshead
and imported photoelectric encoder for displacement measure. This
machine is accompany with the digital multi-channel closed loop
control system which applicates the latest moitoring and control
systems with lots of advanced profassional and technical
development. Control software can automatically finger out routine
data, such as tensile modulus of elasticity, extend rate after
rupture, non-proportional extend strength RP0.2, etc. It can
realize three close loops control and real time display many
testing curves of force-displacement, force-time, and
stress-strain. These curves automatically switch. Testing process
control and data processing conform to the requirements of GB. This
machine has the following performances: Auto zero, auto gear
shifting or no subsection, auto indication, auto save, unicontrol
or multistep programmed control, auto stop, auto analysis or
assistant manual analysis, batch test, testing result statistic,
curve select and over load protection. And the machine is
beautiful, multifunctional, and oprates easily and reliably.
