Servo Controlled Universal Testing Machine (Model : EKE-807) |
|
| |
 |
|
| INTRODUCTION: |
The new technology utilised in this series of Servo - Universal Testing Machine is based on the use of PC applications which allow a totally new concept in steel testing. Gone are the old control consoles full of knobs and switches. Thanks to the use of latest technology, hydraulic control functions are now managed from a standard keyboard and mouse.
Our frames differ substantially from the old traditional models because of the originality of their design, new solutions employed and their extremely simple operation. The sophisticated software consists of a complete suite of programs, not only for tension tests, but also flexure bending and compression tests on concrete specimens in compliance with the new pr EN specifications. Other accessories are available to test steel strands and electrowelded steel screen. |

| Standard Followed : EN 10002 ASTM A370 |
|
| Features: |
Machine Frame, Piston / Cylinder Assembly, Electronic Load Cell
» Steel base with rigid steel frame housing the lower grippers.
» Piston / Cylinder assembly mounted on the top of the rigid frame. The piston incorporates the electronic load cell.
» Mobile frame consisting of four high tensile strength columns, upper crosshead directly connected to the piston, intermediated crosshead with compression platen and lower crosshead housing the upper gripper.
» 400mm vertical daylight adjustable in steps of 50mm.
» Hydraulically operated opening and vertical adjustment of grippers by two independent auxiliary cylinders controlled by the push button panel.
» Crosshead displacements controlled by the use of a bidirectional encoder. |

Grippers
» Three sets of standard grippers supplied with the machine to perform tensile tests on rounds and flats.
» Two sets of grip liners supplied with the machine to provide maximum bearing and holding surface for specimens of all sizes.
Safety Features
» Pressure switch which automatically stops the machine when the oil pressure goes over the maximum permitted level.
» Max. travel limit switch to stop the mobile frame at its upper positon.
» Software safety feature which stops the machine when the maximum load is reached.
Control Console
The lower section houses the hydraulic assembly which comprises:
» Hydraulic Pump
» Proportional valve
» Hydraulic valves
» Heat exchanger to control the oil temperature
» Oil Tank
Hardware
The upper section houses the hardware consisting of an electronic card for the control of all functions of the machine having the following specification:
» A/D converter resolution 1/20000
» No. 4 outputs for electrovalves
» Analogical output for load and strain control: 12 bit
» Load cell input
» No.2 RS 232 C serial port output: 9600 baud
Software
The machine can be used either in the manual or in the automatic mode to perform the following tests
» Tensile test on steel and steel reinforcing bars: Standards EN 10002 and ASTM A379
» Tensile tests in general, flexural (transverse) and bending tests on steel : Standards UNI 558
» Flexural test on concrete beams: Standard pr EN 12390-5
» Compression test on concrete specimens: Standards pr EN 12390-3
Once the specimen has been placed in the machine (using accessories if required) and the specimen data introduced, the test is run completely automatically at the press of a button up to the printout of the test certificate and the storage of the test data.
PC & Printer
The machine is supplied complete with latest PC and inkjet printer.
Standard Outfit
The machine is supplied complete with
» Set of grips for round specimens up to 40 mm dia. and flat specimens upto 70 mm wide and 35 mm thick complete with two sets of grip liners : 3 No.
» Set of foundation bolts. 1 No.
» Service Spanner. 1 No.
» Instruction Manual. 1 No. |
