COMPUTER CONTROLLED DIGITAL CONTROL SYSTEM

SCM3000 is a Computer controlled digital system able to conduct the test

either in stroke control or in load control or in strain control modes.Test can be force controlled maintaining the load rate constant in time. The

ECH/FR proposed version has also the possibility of position control by

using a linear (Baluff or equivalent) displacement sensor (250mm)

attached to the piston of the hydraulic actuator or an strain sensor (strain

gage, LVDT gage, etc.) connected to the electronic system through a signal

conditioning.The SCM3000 system included in this proposal includes the transducer

signal conditioners for load (force transducers), stroke (inductive sensor in

the cylinder) and external strain sensors (LVDT gages and strain gages), to

provide high accuracy, low drift and low noise transducer signal with

standard filters.

Computer included with at least these specifications:

MICROTEST will provide latest computer system at least

based on Intel processor, 4GB RAM, 250 GB HDD withtouch screen monitor and support (Windows 7 or latest)

SERVO HYDRAULIC TEST SYSTEM ECH/3000

The controller has the possibility for limiting the load applied during specimen set-

up. The load threshold is user adjustable

The system acts in two ways in this case: by limiting the applied load by the use of

user adjustable alarms (typically maximum/minimum force) and by limiting the

maximum applied pressure by the Hydraulic Power Supply unit

In addition the system has a general limit for all the controlling channels, for the

maximum load for the load cell (full scale limit). The controller has at least two

limits per connected transducer. The hydraulic system consists of hydraulic power pack which gives a continuous

non pulsating flow of a minimum of oil pressure up to 240 bar

Uninterruptible Power Supply (UPS): Uninterruptible Power Supply (UPS )is recommended to

provide power to the servo controller and PC in safe system operation and shut-down.

SAFETY PROTECTION:

The machine includes different elements for safety protection:Test area guard to protect the user: Protective window made in high resistancepolycarbonate to prevent from debris damage or unexpected impact. The cover isup and down displaceable to ease the work or placement of the samples.

Emergency stop to shuts off hydraulics are part of the security elements.

Overload protection: force limits for each scale, depending on the force

transducer range and alarms (selectable by the user in manual or automatic tests).Stroke protection : stroke limits and alarms (selectable by the user in manual orautomatic controlled tests).

Electric protection: CE marking
