GENERAL DESCRIPTION

Frame

Four column high stiffness welded frame tested for stability to EN 12390-4.
Heavy duty spherical seat in lubricating oil bath, allowing initial free alignment at the initial contact with the specimen and automatic jamming up to the end of test.




Compression Machine Platens

See table. Traceable certificate of surface hardness available on request.



Pilot, Automatic Power and Control System

Dual stage pump, centrifugal for fast approach and multi-piston for loading, DC motor, ES Energy Saving technology, manual valves for loading/unloading and frame selection.



Hardware

132,000 points effective resolution, three channels, touch screen graphic display 240x128 pixel, sampling rate 50/sec, large storing capacity on USB pen drive, test data downloadable to PC, Ethernet port, real time management software (optional, see accessories 82-SW/DM DATAMANAGER)



Firmware

Simultaneous display of load-specific load, actual load rate and load/time graph; LAN connection to PC; advanced memory management; multi coefficient calibration.
Recording facility of up to 10 test profiles for each channel including type of test (e.g. compression, flexural, indirect tensile), specimen size and shape, load rate, standard in use and other general information. Each one of the recorded test profile can be recalled automatically to save time




Safety features

Includes: Max. pressure valve to avoid machine overloading; piston travel limit switch; emergency stop button; front door and rear transparent fragment guard.

Verification of force transfer

The conformity of the compression tester to the EN 12390-4 requirements in terms of stability (force transfer) is performed by the verification of the self-alignment of machine components and the restraint on movement of the upper platen.

The compliance of all our EN testers to these stringent requirements is precisely verified using specific apparatus (82-E0105/1 and 82-P0804/E). An incorrect load application may cause premature sample failure and, consequently the resultant strength could be significantly lower than the true resistance.
