Description

This machine has been designed for use, in the field or laboratory to perform tension tests on steel rebars up to 26 mm dia. and compression tests on cylindrical concrete specimens up to dia. 160x320 mm and cubes up to 150 mm, using the appropriate accessories. 
The system includes the Automax PRO-M power and control system for the automatic execution of compression and tensile tests. 


Frame 
The frame consists of a very rigid frame with double acting cylinder assembly.
It includes a set of tensile holders, 4 wedge grips for flats up to thickness of 13 mm, 4  wedge grips for rounds up to 26 mm dia. and 2 sets of grips' liners 4 and 8 mm thick.
Spherical seat and compression platens for concrete specimens are not included and have to be ordered separately (see Accessories).
High precision displacement transducer, 150mm travel, is mounted on the piston/cylinder assembly to obtain stress/elongation graph based on the crossheads separation measurement.

Spherical seat and compression platens for concrete specimens are not included and have to be ordered separately (see Accessories)


AUTOMAX PRO-M Automatic power and control system
Automatically performs steel tensile and concrete compression tests when connected to the relevant accessories. See Technical Specifications.

  • Unlimited storage capacity for test data on internal 16 GB SD card
  • USB port for test data storage on external USB memory stick and for firmware upgrade
  • Ethernet port for PC / Internet /network communication
  • Optional integrated graphic printer including Load-Time plot (for standard failure tests)
  • RS 232 port for data downloading in ASCII format


Firmware (50-FW/UTS included)

  • Execution of compression, flexure, indirect tensile, ACV tests tests in automatic mode with test speed controlled by a closed-loop PID system. 
  • Execution of tensile with:
    • control up to yield by:                      
         * Stress (method B)                         
         * Strain by using extensometer (method A1)  
         * Strain by using crosshead (method A2)     
    • Control after yield by grips' separation     
  • Simultaneous display of:
    • load, stress, actual load rate, load / time graph in standard failure test (compression, flexure, indirect tensile)
    • load, stress, displacement and % elongation (crossbeam), displacement and % elongation (extensometer, if connected), stress/% elongation graph in tensile tests 
  • Elaboration of tension test results: ReH, ReL or Rp and final elongation A conforming to EN ISO  6892-1 and EN 15630-1                           
  • Saving of the specimen failure type (to EN or ASTM) in concrete compressiont tests results
  • Download data to internal printer (optional) or to PC via RS 232 port or to USB memory stick
  • PC / network communication via Ethernet
  • Multi-coefficient linearization of the calibration curve for better accuracy at low loads thus avoiding the use of a second pressure transducer
  • Recording facility for up to 9 test profiles for each channel including: type of test (e.g. compression, flexural, indirect tensile, tension), specimen size and shape, test speed and other general information. Each one of the recorded test profiles can be recalled automatically to save time.
  • Improved PID algorithm and multi PID selection. Up to three different PID settings can be tuned for each channel for a variety of materials (e.g. cylinder with neoprene pads, low strength specimens) and test methods (e.g ACV, flexure, tension)
  • Compatible with the newly released DATAMANAGER software and UTS software packages, tailored for construction material testing laboratories, for remote control, real-time data acquisition and results calculation.
  • Peripheral devices integration with Link-LAB
  • Automatic load measurement verification procedure, by connecting suitable load cells and our digital readout unit to PC
  • Language selection (including Cyrillic and Chinese)
  • Unit selection (kN, ton, lbf)
  • USB port for firmware upgrade and safe backup of the original configuration data (PID, calibration, etc.), in case of loss and/or data corruption. The restore of the machine to the factory settings is easy avoiding the need of any technical support.


Optional UTS software package for Steel Tensile Testing (82-SW/UTS) allowing: 

  • PC remote control of the test
