FOR COMPRESSION, FLEXURE AND TENSILE TESTS,
WITH AUTOMATIC SERVO-CONTROLLED LOAD OR DISPLACEMENT
DEFORMATION CONTROL.
Unitronic 200kN is the universal and versatile machine designed
and manufactured by Matest to satisfy the need of control, research
and test on:
Roads (Marshall, Duriez, CBR etc.), Steel, Concrete, Cement,
Wood, Plastic, etc.
The machine is composed of a sturdy base containing the transmission
components and the hardware control instruments.
The base holds two columns, made of high resistance steel with
ground hard chrome surfacing.
The upper crosshead can be adjusted in height, to hold the accessories
to perform the specific tests.
The lower mobile crosshead is operated by a recirculating ball screw
and rotating lead, that through a servo-controlled motor assures the
correct application of load and constant speed.
The load is applied with a mechanical jack activated by a brushless
closed-loop motor with optical encoder controlled by a microprocessor.
The two crossheads have couplings to fix the different test devices
(see accessories).
The stress is measured by an electric load cell; the measurement
and the displacement control of the crosshead is achieved by the
electronic device incorporated into the machine.
Stroke electric end excursion switches of the upper mobile crosshead
are foreseen to save the machine from accidental handlings.
FIRMWARE:
– Electronic control unit Cyber-plus Evolution with Touch-Screen
colour display, that runs like a standard PC based on Windows
operating system for the management and analysis of the data,
test results, graphs.
– The Touch-Screen icon interface allows an easy set up of the
parameters and immediate execution of the test.
– The machine can be connected to a PC for remote test execution
through suitable Software; the machine can in any case perform
the tests without any external PC, because of the Cyber-Plus
grants performances like a PC.
– Direct connection to Intranet (connection to a LAN network) and
Internet to establish a remote communication and receive an
immediate diagnostic analysis from Matest technicians, or for
uptdates of the software.
– Unlimited memory storage with: 2 USB ports, 1 SD card slot,
RS232/485 serial port.
– Possibility to select different languages.
– Hardware technical details: see p. 19
