Product Details

WAW-C Computerized Servo Hydraulic Universal Tester /

Universal Testing Machine Manufacture

Applications:

Computer Controlled Electro-Hydraulic Servo Universal Testing Machine Model WAW-500C is suitable to test various metallic & non-metallic materials for tension, compression, flexure, bending and shearing strength. It can be capable of testing the characters of materials on physical & technology properties. It is simple, easy to operate and widely used in works, laboratories and high schools for material properties research and quality control. Equipped with computer as well as printer, it can display, record, process and print the test results and can draw test curves automatically.

Load frame:
• Rigid four column construction & compact design
• Dual workspace design: lower for compression and bending
tests, Upper for tensile test
• Movable lower crosshead providing exceptional ease of
operation
• Accurate force measurement through precision electronic
pressure cell
• With open hydraulic wedge grips for easy change of inserts
and specimen loading
• Integrated displacement photoelectric encoder
• Cylinder mounted at the bottom of the machine

Safeguard
• Overload protection: When the testing load is over 2%-5% of Max. Load, the system will unload.
• Stroke protection: When the piston arrives at the upper limited position, the motor of oil pump will
stop.
• When control deviation exceeds +/-10% of the full scale value, the test will stop automatically.
• Emergency stop switch

Features:
Full Digital Control
The control system adopts special PC control card for testing machine so as to realize digital
adjustment for test load, deformation, displacement zero & gain. It is easy to operate & in high
reliability.
Realize database management of test parameters & test results, which can be stored according to
standard format facilitating other software to be analyzed and transferred.
Completed control mode & intelligent expert system. With auto- processing control function, it can
complete smooth switch of various modes in order to satisfy test requirements for various kinds of test materials & test standards at home & abroad.
Control software has the auto-adjusting function of test hardness, which assures system optimization for every kind of specimen rigidity.
Perfect graphic function, which can realize the arbitrarily magnifying, decreasing, equaling, adding,
indicative display and print of all kinds of test curves, the test point searching as well as the
simultaneous display and print of several kinds of test curves. Data processing supposes
self-disposing and input disposing of graphic human computer interaction, which facilitates the check and contrast of the test result.
The client can self-define the output of the test report, which makes the report format have very high flexibility.
Modularization design facilitates the software upgrading, function spreading as well as the second
development.
