Universal Testing Machine For Steel Strand Computer Hydraulic
Standards:
EN ISO 6892-1, EN ISO 15630-1, EN ISO 7500-1, EN 10002, ASTM A370, UNI 7676
Description:
The hydraulic power source is used to drive, and the measurement and control system is used to collect and process the test data. It is composedof four parts: test host, oil source (hydraulic power source), measurement and control system and test instruments. The accuracy level of the test machine is better than level 1.
It can meet the standard test requirements in the international regulations on tensile test of steel strands, and can calculate the tensile strength, elastic modulus and other performance indicators of the measured materials.
The testing machine is a six column, double space structure. There is a tensile space between the upper beam and the lower beam, and a compressed space between the lower beam and the test bench. The test space is automatically adjusted by driving the lower beam up and down through the rotation of the sprocket and the lead screw mother. The upper and lower crossbeams are equipped with hydraulic control clamping jaws, which can be equipped with special jaws for steel strands for Φ 8～ Φ Tensile test of 18mm steel strand; The bottom end of the lower crossbeam of the standard model is equipped with an upper pressing plate, and the test bench is equipped with a lower pressing plate with a spherical structure, which can be directly used for compression test.
Features:
l Six column providing superior axial and lateral stiffness and precision alignment
l Two different work spaces, the upper one for tension and the lower one for compression, bending and shearing, for a comfortable test execution
l High precision load cell, class 1 and class 0.5 calibration
l Digital displacement transducer for the best positioning and measuring accuracy
l User friendly remote for Multifunctional control
l Hydraulic jaws, for stronger clamping of the specimens
l Overload protection limit sensor
l Long piston stroke for the most convenient and easy adjustment and testing of different sample lengths
l Easy calibration procedure
l Remote control via software, text execution, data analysis available
l Software updates and modification installation available via email or remote support
l Diverse and robust configurations for test end options, graph options, PID values, crosshead movement speeds etc
l Different Testing Methods including cyclic, creep, relaxation, keeping etc
l View data and graphs of ran tests
l Determine and analyze data points such as yield point, breaking point, modulous etc
l Test report printing options include direct to printer or excel file export
l Test report data can be configured to show only necessary data and to exclude unused data
l Raw data analysis for detailed test data
l Exportable to excel and customizable to show user required data
