'FIE' 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
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 of 0.01mm 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.
Typical HGFL design includes a basic universal testing
machine frame with open type crossheads and hydraulic
wedge action grips.
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 nonpulsating oil flow. Hence the load application is very
Hand operated release valve & motorized control valve 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
Control by this valve allows extensometer reading to be
Another Power pack is used to operate wedge action grips
by means of hydraulic cylinder by using solenoid valve
For Hydraulic Wedge action grips separate control remote
is provided with selector switches indicating clamp –
declamp and null positions.
Principle of Operation for - Model: UTES-HGFL-TS
UTM right control valve is Servo Controlled in close loop
mode as per mode selection. Following control modes
1) Standard Manual control
2) Load rate control
3) Elongation rate control
4) Load hold mode
Also Auto start, Potentometric start &initial value open start options are available for test start to take care of slippage & different specimen types.
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.
Computerized Touch Screen Control Panel Series:
Micro Controller based panel incorporating state of art
technology with following features :
Front panel touch screen display
Data entry of test parameters including pre-load,
rupture %, Safe Load & Specimen data etc.
Online graph of load Vs Displacement directly on
USB Printer port for printer interface with graph &
result print out.
Facility to export the result/ Data to PDF, EXCEL &
Windows based software available for online graph
on PC, Data analysis, Statistics, Point tracing,
superimposing graphs to compare with standard,
zooming graph etc.
