Universal Strength Test Equipment Computer Control Lab Hydraulic Tensile Testing Machine
Introduction:
Hydraulic Tensile Testing Machine is suitable for doing testing experiments such as the tensile,
compression, bending and shear testing for all kinds of metal
materials and nonmetal materials such as plastic, concrete, cement
and so on.
The oil cylinder is set on the bottom in the machine, and with
double space frames, the test space can be adjusted automatically.
The control unit is composed of computer and control system, it
process stress, strain and displacement control modes, the test
data can be stored at will, and the data and curves can be
reanalyzed, part amplified and data re-edition, test conditions
(specimen, measurement) are programmable, all the mechanical
properties can be obtained automatically, and print whole test
report and curve.
Main Features:
1, Structure: The machine has four column and double screw with
strong stiffness,oil cylinder down setting.It is The main engine
consists of an adjustable support and a working frame
Element of the machine
2, Transmission system:Screw no move, beam go up and down
3,Control system: full digital control system, realize the test
force, specimen deformation, piston displacement and test process
closedloop control. It can also print the complete experimental
report and curve. It comprehensively conforms with GB/T228-2002
requirements.
4, Multiprotection: Stroke protection: When the ram arrives at the
upper limited position, the motor of oil pump will stop,it is with
Position limiter; emergency switch; the control system can protect
automatically once over-load, over-currency, over-voltage,
over-temperature
5. Load:adopting load cell to ensure high accuracy, reliability and
consistency;
6. Displacement:adopts optical encoder with high accuracy and
stability;
7.Strain:Adopt high accuracy electronic extensometer

Brief Introduction STC300 Control System
STC300 all-digital closed-loop control system has many advanced
features and technological innovation, mainly reflected in:
● To achieve the test force, the specimen deformation, piston
displacement and testing process, the four closed-loop control；
● Data acquisition system is composed of 4-way high-precision
24-bit A / D converter channels. The maximum resolution of up to 1
/ 300000, full regardless of section；
● Use BB, AD, Xilinx and other original brand-name integrated
device, all-digital design；
● Meet the PCI standard, computer and installation of automatic
identification,；
● Electronic measurement systems without analog components such as
potentiometers to ensure interchangeability for easy maintenance
and replacement.
