• Simple controls for easy of operation.
• Robust staining frame of an extremely rigid construction.
• Safe operation ensured be means of safety devices.
• Fully enclosed and protected pendulum.
 

Application :

 Universal Testing Machine is designed for testing materials and other materials under tension, compression bending, transverse and shear loads.

 

Power Pack :

The power pack generates the maximum pressure of 200 kgf/cm2 the hydraulic pump provides continuously non-pulsating oil flow. Hence the load application is very smooth.

Hydraulic Controls :

Hand operates wheels are used to control the flow to and from the hydraulic cylinder. The regulation of oil flow is infinitely variable incorporated in the hydraulic system is a regulating valve which maintains a practically constant rate of piston movement. Control by this valve allows extensometer readings to be taken.

Load Indicator System :

This system consists of a large dial and a pointer. A dummy pointer is provided to register the maximum load reached during the test. Different measuring ranges can be selected by operating the range selection knob. An overload trip switch is incorporated which automatically cuts out the pump motor when the load range in use is exceeded.

Pendulum Dynamometer : 

This unit permits selection of favorable hydraulic ratios producing relatively small frictional forces. Pressurised oil in the loading cylinder pushes up the measuring piston proportionately and actuates the special dynamometer system. The piston is constantly rotated to eliminate friction. The dynamometer system is also provided with an integral damper and ensures high reliability of operation. The load transmitted to the dynamometer is transferred through a pendulum to the load indicator.
Accuracy Calibration : 

UMA 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 BS : 1610 : Part 1 :1992 and IS 1828 : (Part 1) : 1991.

UMA Universal Testing Machines comply with Grade "A" of BS : 1610 : Part 1:1992 and class 1 of IS 1828 : (Part1) : 1991
An accuracy of + 1.0% is guaranteed from 20% from 20% of the load range selected to full load. Below 20% of the selected range, the maximum permissible error is 0.2% of the full load reading.
