Compression and Flexural Machines

Product Code:

Description:

• The UTEST Automatic range of single testing chamber and double testing chamber compression and flexure testing machines have been designed for reliable and consistent testing of mortar samples.
• These compression and flexure testers are the results of continuous applications and research studies to upgrade the machines  with  the latest technologies and conform the current standards EN 196-1, 459-2, 1015-11, 13454- 2; ASTM C 109, C348, C349 and BS 3892-1, 4551-1 in terms of its technical properties taking into account client requirements by using suitable accessories.
• These machines also meet the requirements of CE norms for safety and health of the operator.
• Compression and flexure jigs, distance pieces, and also removable transparent front-rear safety doors (should be factory installed) should be ordered separately.
• The UTEST automatic cement compression and flexure testing machines allow less experienced operators to perform the tests.
• Once the machine has been switched on and the specimen is positioned and centred by the help of centring apparatus.

The only required operations are:

• Setting test parameters, including pace rate (only required when the specimen type is changed.)
• Choosing the compression or flexure frame by using   the changeover valve.
• Pressing the START button on the control unit.
• The machine automatically starts the rapid approach; switches   the test speed after 1% of the load capacity of the machine and   stops once the specimen failure.
• Automatically saves the test parameters and test results.
• The UTEST UTC- automatic cement compression and flexure testing machines consist of very rigid two column single or double chamber frames (see table) and automatic hydraulic power pack with U-Touch PRO Control Unit.

Power Pack:

• UTC-4830.FPR Automatic Hydraulic Power Pack with U-Touch PRO Control Unit is designed to supply the required oil to the load frames for loading.
• Very silent power pack can load the specimen between 50 N/sec to 2.4 kN/sec with an accuracy of ±5%. A Rapid approach pump is supplied as standard.
• Safety valve (maximum pressure valve) is used to avoid machine overloading.
• The motor which drives the dual pump is an AC motor and 0.75 kW and it is controlled by Omron J7 motor inverter.
• The variation in the oil flow is executed with the variation of the rotation speed of the motor.
• A distribution block is used to control the oil flow direction supplied by the dual stage pump and those are fitted to solenoid valve, safety valve (maximum pressure valve), low pressure gear pump and high-pressure radial piston pump
• The dual stage pump is formed by two groups, one is low pressure gear pump and second high pressure radial piston pump.
• On the dual stage pump, a high delivery, low pressure gear pump is used for rapid approach, while a low delivery, high pressure radial piston pump is used for test execution.
• The rapid approach facility shortens the time interval from piston start until the upper platen touches to the specimen.
• This excellent feature helps to save a lot of time when a large number of specimens are going to be tested.
• The oil tank includes enough oil to fill the mechanism which pushes the ram during the test.
• The level and oil temperature can be seen on the indicator fitted to the tank.
• It has 20 L capacity.
• Hydraulic motor oil, number 46, must be used.

U-Touch PRO Control Unit:

• U-Touch PRO Control Unit UTC-4930.FPR is designed to perform automatically compression, flexure and splitting tensile strength tests of construction materials such as cement mortar, concrete, masonry units/blocks by controlling the Utest automatic compression / flexure testing machines.
• All the operations of U-Touch PRO are controlled from the front panel touch screen display.
• U-Touch PRO Control Unit has easy to use menu options.
• It displays all menu option listings simultaneously, allowing the operator to access the required option in a seamless manner to activate the option or enter a numeric value to set the test parameters.
• Digital graphic display is able to draw real-time “Load vs. Time”, or “Stress vs. Time” graphics
• PLEASE see the pages of “U-Touch PRO Control UnitUTC-4930.FPR” for details of the properties.

UTEST Software for Automatic Compression / Flexure Testing Machines:

• UTEST software USOFT-4830.FPR provides to perform automatically compression, flexure and splitting tensile strength tests of construction materials such as concrete, cement mortar, masonry units/blocks by controlling the Utest automatic compression / flexure testing machines
• The advantages of performing tests on computer with using UTEST Software, such as reporting, graphical output, etc. can be seen in detail at the USOFT-4930.FPR (The UTEST Software for Automatic Compression/Flexure Testing Machines with UTC-4830FPR Hydraulic Power Pack) pages.

Main Features:

• Pace rate control from 50 N/sec (flexure) to 2,4 kN/sec (compression)
• Class 1 (EN) and Class A (ASTM) starting from with the 10 % of 250 kN and 15 kN capacity
• Supplied with factory calibration certificate for load measurement
• Tests automatically with closed loop control
• The tests can be performed by controlling the machine either on U-Touch PRO control unit (UTC-4930.FPR) or on a computer with using free UTEST Software (USOFT-4830.FPR) which is provided free of charge with the machines.
• Load measurement with the load cells.
• Adjustable rapid approach rate

Safety Features

• Maximum pressure valves to avoid machine overloading
• Piston travel limit switch
• Emergency stop button
• Software controlled maximum load value
• Removable transparent front-rear safety doors (Should be factory installed and ordered separately)

Technical Specifications:

• Maximum horizontal clearance for placing sample is limited with the border of the platens.
• Sample must be placed such that its ends will not overlap the ends of platens and it must be centred perfectly.

Due to the continuous development of our products, the goods supplied may vary in detail to that illustrated on this Website.
