It can be used with a MATEST testing machine to be selected
among the Servo-Plus Evolution models (ref. C104N, see p. 224).
The appliance includes:
It is an hydraulic installation and has a high performance valve
directly controlled by the digital unit that grants the automatic
control of the pace rate increasing the load, keeps a certain load
and than controls the pace rate decreasing the load.
The setting of the pace rate is made by a very sensitive valve
controlled by a step by step motor and it allows a micrometric
action on the pace rate granting excellent results.
A laser position detector allows a rapid positioning of the piston.
This grants a touching sensitivity of test starting of about 0.1 per
thousand of the maximum capacity.
ELECTRONIC MEASURING SYSTEM
The high performance control and data processing unit controlled
by a 32 bit microprocessor, can manage up to 8 high resolution
channels for the control of load cells or transducers with strain
The unit contains two Analogical/Digital last generation converters
with 24 bits resolution. The system processes the signals
coming from the load cells and from the extensometers giving all
the results required for a further processing following the most
updated International Standards for this application.
DATA ACQUISITION AND PROCESSING SOFTWARE UTM2
LICENSE FOR ELASTIC MODULUS TO EN 13412
The software has been developed on the working line of the
already known software UTM-2 (windows menu). It contains the
profiles of the main Standards used, but the user can modify as
he likes and personalise the test profile, that will be effected in a
completely automatic way by the testing machine.
The user can introduce a list of dates concerning the specimen that will be tested and the kind of test that he wants to make: shape of the
specimen, dimensions, age of the specimen, average expected breaking value, etc… The appliance allows verifying the proper reading of the
extensometers and, if everything is within the expected tolerances, it manages the average deformation value read by the transducers and
processed by the digital unit, than it transmits by means of the serial communication port RJ (Network Connection) to a Personal Computer, that
can be already by the end user or supplied separately (not included with the Software), all the dates of the test. These dates will be processed
by the software and transformed in a graph load/deformation and load/time, following the International Standards.
The software gives the possibility to print on a standard printer a test certificate reporting all the dates concerning the test and the specimen and
the graph of the test. The Software includes the license “Servonet” mod. C123N while the extensometers (two models are proposed: A and B)
are not included in the standard supply, and must be ordered separately (see accessories).
Note: The Elastic Modulus on Mortars mod. E190N can be used together with:
A) EXTENSOMETERS (STRAIN GAGES), SINGLE USE, ELECTRIC,
available in different sizes, mod. C125-10 to C125-13
B) EXTENSOMETERS /COMPRESSOMETERS, electronic, universal,
mechanical frame, mod. C134 (see accessories)
AS AN ALTERNATIVE:
EXTENSOMETER / COMPRESSOMETER, ELECTRONIC,
UNIVERSAL, MECHANICAL FRAME.
It can be used only with samples
having minimum height of 130 mm
Technical details: see p. 286

C125-11 Base length 20 mm
C125-12 Base length 30 mm

KIT for the application of single use extensometers composed by:
glue, welder, solder, cleaning liquid, accessories, the whole in carrying
INTERFACE MODULE, needed accessory to connect up to 4
electric single use extensometers. This module allows also the
automatic calibration of the zero and of the measuring range after
a special thermal compensation. This grants a five times better
accuracy than the one requested by the Standards.
