UNIVERSAL TESTING MACHINE

Universal Testing Machine – Computerized – Mech.CS.UTE

Application

Universal Testing Machine which is available in electronic and computerized functioning. This machine is used to test the tensile and compressive properties of material. The reason Universal Testing machine is named so because it can perform all the tests right from compression, bending to tension and examine the material in all mechanical properties. We offer these in grade of 10T, 20T, 40T, 60T and 100T.

Accuracy & Calibration

All Mechatronic Control System’s Universal Testing Machines are closely controlled for sensitivity, accuracy and calibration during every stage of manufacture. Every Machine is then calibrated over each of its measuring ranges in accordance with the procedure laid down in British Standards 1610: 1964 and IS: 1828-1975. Mechatronic Control System’s Universal Testing Machines Comply with grade “A” of BS : 1610 : 1964 and grade 1.0 of IS -1828-1975 An accuracy of + 1 % is guaranteed from 20% of the load range selected to full load. Bellow 20% of the selected range, the maximum permissible error is 0.2% of the full reading.

Principle of Operations

Operation of the universal testing machine is by hydraulic transmission of load from the test specimen to a separately housed load indicator. The 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 leverage to the 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 the specimen

Machine consists of:

• Straining Unit
• Control Panel Power Pack
• Hydraulic Controls
• Load Indicator System
• Automatic Continuous Roll Load – Elongation Recorder

Electronic Extensometer

Mechatronic Control System offers electronic extensometer EE 1 to measure material extension with a resolution of one micron. Strain gauge type extensometer to be used up to elastic limit to determine important parameters like 0.1%, 0.2% proof stress and Young’s Modulus.
