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 a set of tensile grip, UTM-4018 hydraulic power pack for tensile testing grips,  jaw faces for round and flat samples and a set of compression platen.

POWER PACK

Servo controlled hydraulic power packs with servo valve and advanced power packs used on UTM-6060.SVD2, UTM-6100.SVD2and UTM-6200.SVD2 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.

EXTENSOMETER

Extensometer can directly measure deformation of specimens. It either measures separately thermal expansion strain of specimens or eliminate thermal expansion to avoid effecting deformation of specimen.

Data Acquisition & PC Software (USOFT-6060.SVD2)

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.

Following tests can be done with the UTEST software.

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 weight, 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 continuously 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 standard 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 synchronized 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
