Electronic Universal Testing Machine is designed for testing Ferrous & Non-Ferrous materials under tension, compression bending, transverse and shear loads. Hardness test on metals can also conducted.
Machine Consists of –
Straining unit :
This consists of a cylinder motor with chain and sprocket drive and a table coupled with the ram of the hydraulic cylinder,
mounted on to a robust base.
The cylinder and the ram are individually lapped to eliminate friction. The upper cross-head is rigidly fixed to the table by
two strengthened columns.
The lower cross-head is connected to two screwed columns which are driven by a motor. Axial loading of the ram is
ensured by relieving the cylinder and ram of any possible side loading by the provision of ball seating.
A Rotary Encoder of minimum resolution 0.1mm is provided to measure the deformation of the specimen.
Tension test is conducted by gripping the test specimen between the upper and lower cross-heads.
Compression, transverse, bending, shear and hardness tests are conducted between the lower cross-head and the
The lower cross-head can be raised or lowered rapidly by operating the screwed columns, thus facilitating ease of fixing
of the test specimen.
The Control Panel consists of a power pack complete with drive motor and an oil tank, control valves and electronic
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.
Hand operated wheels are used to control the flow to and from the hydraulic cylinder.
The regulation of the 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 reading to be taken.
Principle of Operation for - Model: UTE
Operation of machine is by hydraulic transmission of load from the test specimen through pressure transducer 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 pressure transducer housed in the control panel.
The transducer gives the signal to the electronic display unit, corresponding to the load exerted by the main ram.
Simultaneously the encoder fitted on the straining unit gives the mechanical displacement to the electronic display unit.
Both the signals are processed by the microprocessor and load and displacement is displayed on the digital readouts
Electronic Control Panel (Series Universal 2001-UTE):
Microprocessor based panel incorporating state of art technology with following features -
Front panel membrane type key board for machine operation with numeric keys for data entry.
