Tenders Description & Specification for Multitest Computerized Control Console
Multitest Computerized Control Console
Suitable for any kind of test from basic failure tests (compression, flexure, splitting, tension) through cyclic tests for elastic modulus and poison ratio determination up to advanced displacement controlled tests
Suitable for any user: 4 easy-to-use software packages available, each one tailored for a specific test method, guiding the operator through all the test phases
Suitable for any type of sample, can be connected up to 4 frames ranging from 15 kN up to 5000 kN in compression and 500 kN in tension
Suitable for any budget: the machine can be upgraded in step-by-step investments by adding suitable testing frames, accessories and dedicated software packages
DC-driven variable speed pump for silent operation, energy saving and highly accurate drop-by-drop oil flow for precise control during complex tests
500 Hz high control frequency for optimum oil pressure adjustment during critical tests
Double frame control, expandable to four, with active frame selection via software
Test cycle with closed loop PID control automatically performed by pressing the start button via PC
Soft platen-to-specimen contact and smooth load rate control from very beginning of the ramp.
Technical Specifications:
Hydraulics
Dual stage pump: centrifugal low pressure for fast approach and automatic switching to radial multi-piston high pressure for loading
DC motor. 720 W, 50-60 Hz
Flow-sharing technology to perform loading and unloading cycles
Maximum working pressure 650 bar
Third and fourth frame option, active frame selection by software
ES Energy Saving technology to reduce power consumption and silent operation.
Hardware
High frequency closed-loop P.I.D. control
Control frequency 500 Hz
131.000 points effective resolution
Sampling rate 250 Hz
6 channels to measure strain values with transducers (LVDT, magnetostrictive, potentiometetric)
4 channels for strain measurement with strain gauges
Digital linearization of the calibration curve (multi-coefficient)
4 channels for load sensors (pressure transducers and load cells)
Memorization of the calibration curve enables sensors to be connected and used immediately.
