ELECTROMECHANIC COST EFFECTIVE SERVOCONTROLLED MACHINES - ELECTROTEST SERIES
According to standards: UNE-7-474-92, DIN-51221, 51223, 51227, 51228, BS-1610 and EN-10002-2
The combination of ELECTROTEST testing frames with IBERTEST software & control modules and adequate testing fixtures guides to excellence in materials testing.
Thanks to the versatility and free testing distances, depending on the testing devices and maximum capacity of load cells incorporated, these machines are particularly adequate for the following type of tests:
- Two high precision screw balls and two guided columns, to ensure an optimum load division throughout the testing frame and a linear displacement of the mobile crosshead.
- Automatic positioning, via software, of the mobile crosshead to an initial position fixed for serial or repetitive tests.
- Enables the use of equipments for tests at high and low temperatures, with no need of modifications thanks to the large dimensions of the testing frame.
- Different testing devices totally interchangeable, with no necessity of moving the load cell. Devices can be mounted by the user himself in a few seconds, thanks to a standardized attachment system.
MAIN FEATURES
|
Testing frame with two high precision ball screw drivers and two steel, chromate and ground guide columns to enable a linear displacement of the mobile crosshead, an optimum load and a high structural rigidity. Control system by means of the MD2 control unit, with closed loop control for displacement and strain.
Strength measuring system by means of universal load cell (tensile – compressive testing) with high precision and repeatability extensometric bands
|
Class: 1 as per ISO 7,500 Displacement measuring system: by means of an encoder (digital pulse transducer) located on the motor axis, with an accuracy of +/- 0,005% of the maximum speed (resolution 0.001 mm).
Servocontrol: strength, displacement and strain. Displacement speed: programmable between 0.005 and 500.00 mm/min. |
 |
Connecting the control unit to a PC with WINTEST software you can operate with the following functions: |
|
Cycles: programmable, via software, by keyboard with control by previously established sections (loading / unloading rate or positive / negative displacement, maintenance time and initial and final values of load and displacement). The complete sequence of the sections (cycle) will be repeated as many times as programmed by the user. Report generator: Automatic creation of reports configured by the user himself, including the same graphs obtained in the test and the statistic graphs importing the BMP files. |
Statistics: enables to display tests per families, data as well as diagrams, to calculate the average values and the typical deviation on all the data of the selected files and generate graphs and comparison diagrams, (histogram by bar diagram, Gauss distribution chart, results sampling, comparison of test curves by overlapping them and three-dimensional comparison diagrams (in strips, in volumes), etc. Once the diagrams are generated as desired, it is possible to print them or save them as a BMP file. Graphic representation: on screen display of diagrams and tests results with possibility of indefinite diagram zoom. |
GENERAL DESCRIPTION
TESTING FRAME
Manufactured according to the UNE-7-474-92, DIN-51221, 51223, 51227, 51228, BS-1610 and EN-10002-2 (1990) standards.
The testing frame includes:
|
- Large and comfortable testing frame, over dimensioned and with a high structural rigidity with two guided columns and two screw balls to ensure an optimum division on loads in the testing frame and a linear displacement of the mobile crosshead.
- The different materials testing devices are totally interchangeable, with no need to move the load cell. These devices can be mounted by the user himself in a few seconds, thanks to a standardised attachment system.
- End of stroke of the mobile crosshead.
- Automatic positioning, via software, of the mobile crosshead to an initial position fixed for serial or repetitive tests.
- Cyclic tests between prefixed limits or with control in prefixed sections, in strength (via software with the keyboard) or displacement (by means of adjustable mechanic limits or programmed via software with the keyboard).
- Wide range of speeds (0.005 and 500.00 mm/min). Other possible speeds on demand.
- Displacement measure by encoder (digital pulse transducer) with a resolution of 0.001 mm.
- Enables the use of equipments for tests at high and low temperatures, with no need of modifications thanks to the large dimensions of the testing frame

LOAD MEASURING SYSTEM Universal strain gauge load cell (tension compression), high precision and repeatability. Same capacity as the maximum load of the testing frame.The quality of the load cells used, guarantees the 1 class according to ISO 7500-1 within the measuring range (1 to 100% of the nominal capacity). The data obtained in the load cell is used for two applications: test results and to allow the MD series control system to calculate the kN/sec load speed. Additional load cells could be installed, to increase the load measuring capacity or for special applications. Anyhow, the 1 class is always assured.  |
DISPLACEMENT MEASURING SYSTEM By means of a resolver which allows a 0,001 mm displacement resolution. The data obtained in the resolver is used for two applications: test results and to allow the MD series control system to calculate the mm/min crosshead displacement speed.
