GENERAL DESCRIPTION

UTM-6000, UTM-7000 and UTM-8000 computer controlled servo hydraulic universal testing machines are suitable to test various metallic and non-metallic materials and can carry out tension, compression,  flexural and bending  tests. The capacity of UTM-6000 is 600kN, of UTM-7000 is 1000kN and UTM-8000 is 2000kN. On all models load cell is used for load measurement to achieve best load accuracy during test. The load accuracy of the systems is ±1% down to 2% of the full capacity.  Strain measurements are done by the electronic displacement transducers built in the machine. Displacement or strain measurement can be also done external extensometer fitted to the specimen. The accuracy of the strain measurement on frame is 12.5 microns.

UTM-6000, UTM-7000 and UTM-8000 systems are guaranteed to meet EN ISO 6892-1, EN ISO 15630-1, EN ISO 7500-1, ISO 679, ISO 1920-4, ASTM E 290 and other international and national standards. Servo hydraulic universal testing systems can carry out tension test, compression test, bend test and flexure test by two pace rate type including load control and displacement control . Those two control parameters can be switched during the test. According to the preset condition, the systems can realize constant-rate loading, loading according to preset curve, testing with constant-rate displacement.

With powerful testing software, UTM-6000, UTM-7000 and UTM-8000 systems can acquire, dispose automatically testing data, display real-timely stress-strain curve, load-deformation curve, load-time curve and other related curves, at the same time, can save, output, print test report and data with customized format. With the help of advanced Material Testing Software the machine can be widely used in ultimate R&D department, Universities and Academies, Quality control and Inspection department, calibration centers/laboratories and industry.

LOAD FRAME

Load frames used on Hydraulic Universal Testing Machines has a motor driving system to set distance between grips for test set up has a rugged six column construction for exceptional load frame rigidity. All models feature two test spaces for tension test and compression/flexure and bending test. User can quickly change between tension and compression/flexure and bending testing without having to remove heavy fixtures. This flexible design also helps to ensure safety, reduces operator effort and improves productivity. The distance between the grips can be set by motor driven hand set system for different specimens. With an open front hydraulic wedge grips user can change jaw faces and load specimen easily.

All frames are supplied complete with jaw faces, compression platens and bending fixtures. 

POWER PACK

Servo controlled hydraulic power packs with proportional valve and  advanced power packs used on UTM-6000, UTM-7000 and UTM-8000 to perform tests under load and displacement controls. The frequency of the P.I.D controller and data acquisition is 1000 Hz. Power packs are designed to supply the required oil to the load frames for loading, unloading or low cycle dynamic testing and also hydraulic grips.

All the operations of Data Acquisition and Controls System can be controlled from the touch screen front panel of a 240x320 LCD display or computer. There are extra  two analogue channels for sensors such as Load Cells, Pressure Transducers, LVDT's, strain gauges, extensometers etc. built in the system, and one TTL displacement transducer input exists for frame displacement measurement. Additional two analogue channels can be configured optionally on the order stage for different type of applications.

Power packs can be connected to the computer through Ethernet port for advanced test cycles, data acquisition and reporting. The modulus of elasticity, Poisson's Ratio and compressibility parameters is easily and properly evaluated by attaching extensometers or LVDTs on to the sample. All the calibration values of the transducers and also all the test parameters for the last test is automatically stored on the control unit. Power pack incorporates a pressure safety valve for each frame separately with a cooling unit.

Tensile Test of Reinforcing Ribbbed Steel Bars

EN ISO 6892-1

Tensile Test of Metallic Materials

Universal Test Software is developed for testing tensile strength of Reinforcing Rubbed Steel Bars  and Welded fabric for the Reinforcement and Prestressing of Concrete. The software includes control of machine, data acquisition, saving them and preparing reports. The user can prepare his own report and also can send the results to Microsoft Excel environment. The software accepts sample's weigth, length, diameter and gauge length as input, and then the user can give start test command to the machine. The samples calculated diameter gives user a perspective about the density of rebar prior to the test. The software continously updates load,stress and elongation percentage till the break point. When the test is completed the yield point is calculated and indicated on the graph. Each report is a group of 42 samples where 14 different diameters had been entered. The software is prepared as making at least 3 samples for each diameter. This gives user a total report about all the batch. The report includes all standart limits and one can easily check whether the sample can be acceptable. These limits are minimum yield, minimum tensile, minimum break elongation value,Tensile per yield ratio etc. The user can zoom on the graph for further inspection Break elongation value can be syncronized with the manual  measurement after the test has been completed for the users that do not use extensometer.

  • Foreign Language Support and Customizable User Interface

All contents of experimental data and additional information can be organized by user. Software can be performed in x different languages.

  • Capability to Save 24 test results of different specimens in one test folder

Test results, graphics and properties of 24 different specimens can be saved in one folder. Old test folders can be reviewed and be edited easily. Advanced Graphic User Interface Software.
