Application :
FIE Electronic 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 conducted.

Principal of Operation :
Here UTM Right Control Valve is Servo Controlled in close loop mode as per mode selection. Following control modes available :
1) Standard Manual Control
2) Potentiometric Control
3) Load Rate Control
4) Elongation Rate Control
5) Load Hold Mode
6) Strain Rate Control
Also Auto Start, Potentiometric start & Initial Valve open start options are available for test to take care of slippage & different specimen types.

Load is applied by 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. Simulteniously the digital encoder fitted on the straining unit gives the mechanical displacement.

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 strenthened 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.

An displacement scale with a minimum graduation of 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 & hardness tests are conducted between the lower cross-head and the table.

The lower cross-head can be raised or lowered rapidly by operating the screwed columns, thus facilitating ease of fixing of the test specimen.


Tension Test Tension Test

Control Panel :
The control Panel consists of a power pack complete with drive motor and an oil tank, control valves and electronic display unit.

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 operated Release Valve & motorised 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 movement. Control by this valve allows extensometer reading to be taken.


Compression Test Compression Test

Electronic Control Panel : (FIE- Servo)

  • n Electronic panel 8085 microprocessor is used for basic UTM operation & an 8 bit dedicated microcontroller is used for close loop & Servo Control.
  • Panel is having parallel printer port, RS 232 C serial port for PC interface.
  • 2 lines x 8 digits 7 segment display & membrane keyboard for data entry.
  • 20 data sets and 50 results storage.


Software :
Windows based basic software for Servo Control is in standard scope of supply.

  • Real Time graph, User friendly software.
  • Extensive graphics on screen for curve plotting, magnification and zooming.
  • Software features include Graph comparison, point tracing facility. Different units selection for load & displacement.
  • Statistical evaluation with water fall dig., Mean deviation, frequency distribution, Skew dig., Histogram. Also calculates max. value, min.value, Mean Value, Variance, Standard Deviation. (Other statistical parameters on request). Selectable batch & statistical printouts.
  • Evaluation of wide range of user selectable parameters such as % elongation, % reduction in area, young's modulus, yield stress, proof stress etc.
  • Optional Software packages for Extensometer, Shear Bend, Torsion, Rubber, Textile testing etc.

Accuracy and Calibration :

All FIE Electronic 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 : Part 1 : 1992 and IS : 1828 : Part 1 : 1991.

Fie Electronic Universal Testing Machine comply with Grade "A" of BS : 1610 : Part 1 : 1992 and class 1 of IS - 1828-Part 1:1991. An accuracy of + 1% is guaranted from 2% to 100% of the capacity of the machine.

Below 20% of the selected range , the maximum permissible error is 0.2% of the full load reading.
