Hydraulic Universal Testing Machine

EN ISO 15630-1, EN ISO 6892-1

UTM-4000.FPR Universal Hydraulic Tensile Test Machine is designed to test the ferrous materials for structural values such as yield strength and tensile strength. Apart from tensile tests, Universal Test Machines can also be used for compression tests  up to the capacity of the machine.

Maximum security is maintained on 600kN capacity Universal Test Machine by limit switch on the lower grip and piston as well as the safety check valves on the hydraulic system. Hydraulic power unit works silently.

0-30 mm flat and 8-32 mm round samples can be tested with a user friendly hydraulic jaws that comply with standards.

Load cell is used for load measurements. Strain measurement is done by the electronic displacement transducer built in the machine if required external extensometer fitted to the specimen also can be used for strain measurement. Strain measurements can be done directly from the extensometer fitted to the specimen.

Tests can be done fully automatic by digital control unit or computer. Machine complete the test with the set pace rate and turns to start position automatically.

UTM-4000.FPR Hydraulic Universal Testing Machine, features two test spaces for tension tests and compression tests. User can quickly change between tension and compression 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. With open front hydraulic wedge grips user can load specimen easily.

U-Touch PRO CONTROL UNIT

The control unit unit is designed to control the machine and processing of data from load-cells and pressure transducers which are fitted to the machine.All the operations of U-Touch PRO is controlled from the front panel touch screen display.

U-Touch PRO Control Unithas easy to use menu options. It displays all menu option listings simultaneously, allowing the operator to access the required option in a seemless manner to activate the option or enter a numeric value to set the test parameters. Digital graphic display is able to draw real-time "Load vs. Time", or "Stress vs. Time" graphics

• Automatically calculates % strain, breaking point, stress.  
• Automatically calculates yield point and calculated diameter      
• Closed loop control with automatic test procedure
• Can control 2 frames, by using selector valve and selectimg channel
• Stand-Alone control or computer control
• Also two additional channel inputs for displacement measurement (Activated only by the Utest technical service)

• Multi-Point calibration function for the channels.
• Programmable digital gain adjustment for load voltage and current transmitters

• Real time numeric display of load and load pressure with test graph.
• 3 different unit system selection; kN, kgf and lb
• Ethernet port to connect to a PC or network.
• Optionally supplied-integrated thermal printer (If requested, must be specified in the order)

HYDRAULIC GRIPS

Hydraulically operated grips completely stop the possibility of sample sliding from the grips enabling for correct and definite strain measurements. Hydraulic grips are very safe and user friendly. Hydraulic grips come with grip sets for pulling 8 – 32 mm diameter cylinder samples. The hydraulic grips has an independent hydraulic power unit with a working pressure of 400 bars. Jaw faces for flat samples (UTM-4004) should be ordered separately.

EXTENSOMETER

Different types of extensometers with accuracy of ±0.1% of indicated value are available depending on requirements. Extensometer can directly measure deformation of specimens by quartz-pole. It either measures separately thermal expansion strain of specimens or eliminate thermal expansion to avoid effecting deformation of specimen.

Data Acquisition & PC Software (USOFT-4000.FPR)

The Universal Testing machine can be controlled (Start, Stop commands) by a computer with the software (given free of charge by UTEST). This software provides data acquisition and management for compression, tensile and splitting tensile test throughout the test execution. The advanced functions for data base management provide an easy navigation of all saved data. The test results certificate includes all descriptive information. Therefore, test parameters can be set and details about the test carried out such as client details, test type, specimen type, user info and other information required can be entered and printed out as well as test report and graph.

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.
• Graphical data on the screen is refreshed simultaneously during test procedure Load values can be monitored in high resolution graphics at every 100 milliseconds. User can highlight all 24 different specimen curves or preferred ones in different colors on the graphics. Zooming in–out and dragging can be done easily by mouse. Peak values of curves can be marked on the graphics and user can get load value of any point on the graph via high resolution.
• Able to save frequently used texts in memory and recall them when necessary Frequently used information like name and location of the laboratory, type and dimensions of mostly used specimens are held in memory and can be written automatically by right clicking on information boxes and selecting frequently used text in menu.
• Capable to Access and use previously done test data User can access any data of previously completed tests and use in his/ her new report since most of the tests have same structure and properties.
• Able to edit test parameters of the testing equipment through Software All test parameters supported by testing equipment can be changed remotely via software. All test parameters specified by user are downloaded to the device before initialing the test procedure. By this way predefined device parameters will not cause errors in test results.
• Graphical outputs and reports can be saved as a MS Excel worksheet Test result parameters and graphics are transferred to MS Excel worksheet properly to give user a chance to edit any data and graph easily.
• Maximum Flexibility to edit report and graph templates User can design his/her custom report template and graphic scheme in MS Excel. In software part, user will define which data will be screened in which cell on the worksheet. Therefore , he/she will be able to monitor test results in his/her specific design.
