HYDRAULIC SYSTEM SPECIFICATIONS
- Max hydraulic pressure: 700 bar
- 4 pistons pump granting oil supply from 0.05 to 1.35 l/min
- Forced ventilation oil cooling system
- Pump oil filter with automatic alarms in case of low oil level or
dirty oil filter
- Servo controlled proportional valve with high control frequency
- 2 electronic valves to automatically select the test frame
- Inverter device
HARDWARE AND FIRMWARE SPECIFICATIONS
- 8 channels, each one able to control the test and each one suitable
to connect load sensors (load cells or pressure transducers),
displacement transducers (potentiometric, full bridge, LVDT,
magnetostrictive) and deformation transducers (extensometers,
strain gauges)
- Each channel effective resolution 19-bit, 524˙288 divisions
- Closed loop control with PID parameters adjustable in real time
during the test by the user
- Control frequency can be adjusted up to 200 Hz
- 7” LCD touch-screen
- Sampling frequency can be adjusted up to 4 kHz
ELECTRICAL CHARACTERISTICS OF THE CHANNEL
CONDITIONERS
- Feed LVDT ± 15V
- Output signal from -2.5 to +2.5V DC
- Data acquisition synchronized on all channels
- Calibration of the 8 channels in divisions (up to 40 steps), with
polynomial fun¬ction which allows the best approximation of
readings accuracy over the whole test range
SOFTWARE
- Possibility to control the test by remote via PC
- Software includes the test standards to perform compression,
flexure and splitting tensile tests
- Rocks and concrete elastic modulus tests (see p. 68 and 284)
can be performed, either by following the test standards or by
setting fully customized cycles.
- Toughness of fiber reinforced concrete, energy absorption of
sprayed concrete tests can be performed.
- FRC tests (see p. 305) can be performed (Deflection, CMOD,
CTOD and flexural strength).
- Triaxial test on rocks and Stress-path test procedure, if
completed with C104NLP system for the lateral pressure application
and it is accessories listed at p. 70.
