SSS Make Analog Cum Computerised Universal Testing Machine is designed for testing metals and other materials under tension, compression bending, transverse and shear loads. Hardness test on metals can also be conducted.

Principal of Operation
Operation of the machines is by hydraulic transmission of load from the test specimen to a separately housed load indicator. The hydraulic system is ideal since it replaces transmission of load through levers and knife edges, which are prone to wear and damage due to shock on rupture of test pieces. Load is applied by a hydrostatically lubricated ram. Main cylinder pressure is transmitted to the cylinder of the pendulum dynamometer system housed in the control panel. The cylinder of the dynamometer is also of self-lubricating design. The load transmitted to the cylinder of the dynamometer is transferred through a lever system to a pendulum. Displacement of the pendulum actuates the rack and pinion mechanism which operates the load indicator pointer and the autographic recorder. The deflection of the pendulum represent the absolute load applied on the test specimen. Return movement of the pendulum is effectively damped to absorb energy in the event of sudden breakage of a specimen.

Electronic Control Panel
The electronic control panel is built using 8085 microprocessor which incorporates state of the art technology with following features :

• Front panel membrane type key board for test setup.
• 7 seg digital display of load displacement / extension. Printer port interface
• Serial port for communication with Pc.
• Optional add-on facility for electronic extensometers & electronic load pacer
• Storage of important parameters such as peak load, displacement at peak load & maximum displacement alter test.
• Period selection to take care of initial slippage

Serial Communication & Software Package On Pc
The SSS-UTME series control panel can be hooked to any PC using RS-232 communication port. offers different exhaustive application. Window based software packages on PC to enable the user to effectively evaluate different parameters.

The features include :

• User friendly main menu with pop up menus prompt messages and help windows.
• Extensive graphics on screen for curve plotting, magnification and zooming.
• Evaluation of wide range of user selectable parameters such as young's modulus. yield stress. proof stress etc.
• Advanced file handling for data storage. Printout option for reports. data and graph etc.
• Optional software package for statistical evaluation.
• Custom built application software to suit customer requirements
