ELS50 & ELS60 - Universal Testing MachineELS50 & ELS60 - Universal Testing Machine
Triaxial testing, Uniaxial testing, Unidimensional compression tests, CBR- and Marshall-tests. (optional: tensile testing)
The ELS50 and ELS60 laboratory test presses are equipped with an electromechanical precision drive for load, displacement and speed-controlled tests. It’s used for performing Unconfined compression test, CBR-tests and Consolidation tests. With appropriate installation accessories, triaxial tests can be performed in accordance with DIN EN ISO 17892-8/-9.
The combination of fully retractable load stamps and slide rails on the table top makes it easy to install heavy triaxial cells. The triaxial cell is simply placed on the table top and pushed towards the load stamp until it stops. The cell is centered fully automatically.
Tensile tests (extension tests) can also be carried out as an option.
- Fully retractable thrust plate in the top table with slide rails for easy loading with heavy test cells
- intuitive operation and easy handling with 4,3” touch screen with separate function keys and haptics
- high speed multi-core-system with bus coupling, each drive unit (e.g. horizontal and vertical gear) using it’s own high resolution closed-loop controller with 1 ms sampling time
- precision electromechanical drive for closed-loop load-, displacement-, speed- and stiffness-controlled testing
- precise settlement measurement with digital dial gauge, resolution 10 µm and 1 µm
- electronic load and stroke limitation to prevent sensor damages
- manual adjustment of the thrust plate
- changeable load sensors with automatic detection of the measurement range to adapt different test parameters
- measurement of a external analog signal 0 .. 10 VDC (e.g. pore pressure sensor and temperature sensors)
- Hardware-supported permanent memory (EEPROM) for the calibration values of the connected sensors; a calibration data set is saved for each calibrated sensor
- Serial interface for automatic control and measurement data acquisition via PC and the GeoDESC software
- OPTIONAL: data transfer via network interface / LAN (RJ45)
- several load cells (1 kN, 2 kN, 5 kN, 10 kN, 20 kN, 25 kN, 50 kN, 60 kN)
- digital dial gauges with measurement ranges from 12,5 mm up to 60 mm, resolution 10 µm and 1 µm
- external sensors, e.g. pore pressure sensors for triaxial testing
- accessories for uniaxial testing and unidimesional compression testing (oedometer cells)
- equipment for triaxial testing (triaxial cells, pressure generator, …)
