Determination of the secant compression ELASTIC MODULUS on concrete System: Automatic with pace rate control also when releasing the load.
It can be used with a MATEST high stability frame of 2000, 3000 or 5000 kN capacity coupled with the automatic servo-controlled system Servo-Plus Progress (mod. C104N).
Hydraulic system
It is a 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, keeping a certain load and then controlling the pace rate decreasing the load.
The setting of the pace rate is made by a very sensitive valve controlled by a stepper motor allowing 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 at 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 gages bridge.
The unit contains two Analogical/Digital last generation converters with 24-bit resolution. The system processes the signals coming from the load cells and the extensometers giving all the results required for further processing following the most updated International Standards for this application.
Data acquisition and processing UTM2 software
License for Elastic Modulus on Concrete.
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 customize the test profile that will be carried out in a completely automatic way by the testing machine.
The software gives the possibility to print on a standard printer a test certificate reporting all the data concerning the test the specimen and the graph of the test. The software includes the license mod. C123N, while the extensometers (two models proposed: A and B) are not included in the standard supply and must be ordered separately.
The user can introduce a list of data concerning the specimen that will be tested and the kind of test that he wants to make: the shape of the specimen (cylinder-cube-block), dimensions, age of the specimen, average expected breaking value, etc…
