UTEST Advanced Testing systems can do tests under control of Load / Stress, Displacement and Strain Rate depend on power pack used.

You can find the detailed information about frames, power packs and accessories on different section of this catalogue.

The UTC-4850 and UTC-4860 Automatic Power Packs with Proportional Valve and The UTC-4870  Automatic Power Packs with Servo  Valve are advanced power packs can be used on any testing system ideal for R&D laboratories and Universities for advanced tests with P.I.D. Closed loop control. It can perform tests under load and displacement controls. The frequency of the P.I.D controller and data acquisition is 1000 Hz. UTC 4850 and 4860 Automatic power packs are designed to supply the required oil to the load frames for loading, unloading or low cycle dynamic testing. 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.

The UTC-4850  and UTC-4870 can control up to 2 different frames, UTC-4860 and UTC-4880  up to 4 frames. There are an extra 3 analogue channels for other sensors such as load cells, pressure transducers,displacement transducers, extensometers, etc. built in the system as an addition to the loadcell (pressure transducer) or the pressure transducer on the frame selected by the user.

The power pack automatically controls and supplies oil to the frame which is chosen by the user via the touch screen LCD digital control unit or by choosing the test type from the computer software.

The type of displacement transducer can be TTL or analogue ( It must be same type for all frames )

The main specifications of the UTC-4850 and UTC-4860 power packs are

• -1 litre/minute pump delivery (max) 315 bar, 1.1 kW motor rate
• -Loading-unloading with ±1 % rate accuracy
• -Staying at constant load within 0,01% resolution of the maximum load
• -The control of the load starts from 2% of the maximum load capacity of the system

The main specifications of the UTC-4870 and UTC-4880 power packs are

• -5 litre/minute pump delivery (max) 280 bar 3 kW motor rate
• -Loading-unloading with ± 0,5% rate accuracy
• -Staying at constant load within 0,005% resolution of the maximum load
• -The control of the load starts from 1 % of the maximum load capacity of the system.

All  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 displacement tranducer or extensometers 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. All power packs incorporate a pressure safety valve for each frame separately and a cooling unit.

Main Features of Power Packs

Data Acquisition & PC Software

Advanced Testing Systems 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, flexure and splitting tensile test throughout the test execution for UTC-4850, UTC-4860, UTC-4870 and UTC-4880 advanced power packs.

The software is capable of running the machine in load control, displacement or strain control. The type of graph or test rate can be changed on the fly. The user can set load or displacement values for making machine to wait until the next command. Engineering functions of elasticity modulus, poisson ratio, yield value and energy ( for UTC-4870 and UTC-4880) is automatically calculated. The software can adjust the axes of graphs, supports different type of graphs and calculates 3 different type of elasticity modulus called tangent, linear and secant moduluses. It also calculates poisson ratio. It can set the gains of the closed loop control, make calibration to the pressure transducer or loadcell. It has an easy calibration check facility such as machine waits at %2, %5, %10 of its maximum capacity for easy check of calibration.

Test speed or mode ( displacement and load control) can be changed by user-friendly buttons during the test.

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. The results are exported to Microsoft Excel for advanced research purposes. The data can also be filtered for obtainining intuitive results. The software prepares a summary report.

Following tests can be done with The UTEST Software with proper test machines.are prepares a summary report.

• -Foreign Language Support and Customizable User Interface
• -Capability to Save 24 test results of different specimens in one test folder
• -Graphical data on the screen is refreshed simultaneously during test procedure
• -Able to save frequently used texts in memory and recall them when necessary
• -Capable to Access and use previously done test data
• -Able to edit test parameters of the testing equipment through Software
• -Graphical outputs and reports can be saved as a MS Excel worksheet
• -Maximum Flexibility to edit report and graph templates
