|
The CTE 4C type compression testing machine is designed for conducting
specifically compression test on concrete blocks, stones and many other
similar materials.
|
|
|
Principle of Operation : |
|
Operation of the machine is by hydraulic transmission of load from the test
specimen through pressure transducer to a 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 a pressure transducer house 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 signals are processed by the microprocessor and load
displacement on digital read-outs simultaneously. |
|
|
Machine consist of : |
I) Loading Unit : |
Fabricated base clamped to four columns by nuts. And the piston slides in the
cylinder a cover is provided on the piston to protect it from dust. Thick top plate
is clamped on the upper side of the four columns by nuts. Upper Compression
plate with swiveling is attached to top plate and lower compression plate is
kept on the piston. Three packing stools are provided to keep the required
vertical clearance so the machine is of fixed crosshead type. |
|
II ) Control Panel : |
The control panel consists of a power pack complete with drive motor, oil tank,
control valves and electronic display unit. |
|
|
III) Electronic Control Panel: (Series UniversaI2001-UTE) : |
Microprocessor based panel incorporating state of art technology with
following feature. |
• Front panel membrane key board with numeric keys for data entry.
• 7 segment display to show load and compression.
• Data entry 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 userto effectively evaluated different parameters. |
|
• 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 rnax. value, min value,
Mean value, Variance, Standard Deviation (Other statistical parameters
on request). Selectable batch statistical printouts. |
|
IV) Accuracy and Calibration : |
|
An accuracy of ±2% is guaranteed from 2% to 100% capacity of machine.
Load verification of the testing machine meets the requirement of
BS: 1610-1964 and IS: 1828:2000. |
