|
| Application : |
|
FIE Compression Testing Machine is designed
to test materials and other materials under compression,
bending, transverse and shear loads.
Hardness test on metals can also be
conducted.
|
|
Principal of Operation : |
Operation of the machine is by
hydraulic transmission of load from the test specimen to separately house 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 house in the control panel. The transducer gives the signal to the electronic display unit, corresponding to the load exetted by the main ram. Simulteniously the digital electronic fitted on the straining unit gives the mechanical displacement to the electronic display unit. Both the signals are processed by the microprocessor and load displacement on digital readouts simulteniously. |
|
Machine consists of : |
1. Straining Unit : |
It consists of a hydraulic cylinder
and a table coupled with the ram of
hydraulic cylinder, mounted on robust base.
The cylinder and the ram are individually
lapped to eliminate friction. The cross-head
is connected to two screwed columns and is
driven by a motor, for rapid adjustment of
test height.
|
An elongation scale with a minimum
graduation of 1.0 mm, is provided to measure
the deformation of the specimen. |
Compression, transverse, bending, shear and
hardness tests are conducted between the
lower cross head and the table. |
|
2. Control Panel : |
The control Panel consists of a power
pack complete with drive motor and an oil
tank, control valves and electronic display unit. |
|
A) Power Pack : |
The power pack generates the maximum
pressure of 200 kgf/cm2. The
hydraulic pump provides continuously
no pulsating oil flow. Hence the load
application is very smooth. |
| B) Hydraulic Controls : |
Hand operated wheels are used to control
the flow to and from the hydraulic cylinder.
The regulation of oil flow is infinitely
variable. Incorporate in the hydraulic
system is a regulation valve, which maintains
a practically constant rate of table
movement. |
C) Electronic Control Panel (Series Universal 2001-UTE): |
| Microprocessor based panel incorporating state of art technology with following features, |
• Front panel membrane key board with numeric keys for data entry.
• 7 segment display to show laod and compression.
• Data entery of test parameters including rupture % peak, pre-load, module data, test data & specimen data etc. through numeric key board.
• 20 input data set storage, 50 results storage.
• Maintains data & results during power off.
• Each test facility for generating batch and statistics result.
• Printer port for dot metrics printer interface to print graph and results, batch certificate and simple statistics printout. |
|
Optional Software Packages on PC : |
| The universal 2001-UTE Series control panel can be hooked to any PC using RS-232 communication port. FIE offers different exhaustive application. Window based software package with real time graphon PC to enable that user to effectively evaluated different parameters. |
The features include : |
• Real time graph, user friendly software.
• Extensive graphics on screen for curve plotting, magnification and zooming.
• 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.

Accuracy & 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 BS : 1610 and IS : 1828 : Part 1 : 1992 , Electronic Universal Testing machine comply with the grade "A" of BS : 1610 part 1 : 1992 and lass 1 of IS-1828-Part-1 : 1992 an accuracy of + 1% is guranted from 2% to 100% of the capacity of machine below 20% of the selected range, maximun permissible error is 0.2% of the full load range. |
