Application - Compression Testing Machine
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 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 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 consists of :
I) Loading Unit - Compression Testing Machine
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 - Compression Testing Machine
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 Universal 2001-UTE)
Microprocessor based panel incorporating state of art technology with following feature.
- Front panel membrane keyboard 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 graph on 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.
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.
PC and Printer is not in our standard scope of supply.
