Technical Specifications
Unique technology based on servo-controlled proportional valve optimized for construction materials for load, stress and displacement controlled tests, with superior performances: fast reaction time, excellent sensitivity to minor variations, extremely wide oil flow range.
Performs user defined displacement/deformation tests for research purposes: Unlimited combinations of load/stress, displacement/strain cycles, load/stress ramp sequences and test procedures.
Low frequency dynamic tests with a maximum of 0.1 Hz (depending on the wave amplitude).
All above features extended onto up to 4 different frames ranging from 15 kN to 5000 kN.
Accuracy and reliability thanks to advanced electronics, efficient closed-loop control, high effective resolution, optimized P.I.D. algorithms.
Technical Specifications:
Hydraulics
Hydraulic motorized power pump with automatic double stage mode: low pressure/high flow rate (2l/min) for the fast approach (min.40mm/ min) and high pressure/low flow rate (0.7 l/min) for test execution.
Max working pressure: 720 bar.
Wide flow rate range allowing the control of several frames with different capacities from 15kN up to 5000kN.
Forced ventilation oil cooling system.
High efficiency oil filtering system with anomalies warnings (e.g. low oil level and dirty oil filter).
2 (extendable to 4, see upgrading options) electronic ON/OFF valves for remote automatic selection via PC of the active frame.
Oil flow regulated by servo controlled proportional valve with high frequency driving signal.
Hardware and Firmware
4 for load sensors (load cells or pressure transducers)
4 for displacement transducers (potentiometric, LVDT amplified, magneto strictive) and deformation transducers (strain gauge)
8 active channels (each one can be used by the machine as feedback variable to control test execution):
Single-/dual-ended input with automatic detection
Input signal from -2.5 to +2.5V DC
Zero and gain digitally adjustable
Effective resolution 132.000 divisions, Closed loop control with high frequency PID.
Control frequency: up to 120 Hz
Electrical characteristics of the channel conditioners: Feed from 0.5 to 10V DC (digital selection)
Data acquisition synchronized on all channels
Calibration of the 8 channels in engineering units, via linearization function (up to 10 steps) which allows optimisation of readings accuracy over the whole test range.
