Electronic universal extensometer/compressometer

DETERMINATION OF THE SECANT COMPRESSION ELASTIC MODULUS TEST ON CONCRETE AND MORTAR SPECIMENS

Made of two anodized aluminium pieces, one fixed and the other sliding and housing a displacement transducer that measures with high
accuracy the movement of two conical points made of hardened steel and fixed at the two ends of the electronic sensor.
An aluminium template (optional mod C134-10) is used to regulate and to calibrate the base length. The two conical points are coupled to the surface of the
sample with a rapid and simple fixing system through two elastic adjustable straps.
The instrument is equipped of a mechanical knob to lock and unlock the displacement transducer, allowing to maintain safe the selected base length during the fixing action of the device to the sample. Normally the test is performed on cylinders by using 3 extensometers/compressometers, and on cubes or beams by using 2 or 4 instruments. The extensometer is suitable to test cubes, cylinders and
beam specimens, having minimum height of 130 mm. It is also possible to test mortar prisms 40x40x160 mm by using a reducing length block. Gauge length adjustable from 50 to 160 mm Feeding up to 10 V
Travel: +/- 1,5 mm
Sensitivity less than 0,01 micron
Supplied complete with reducing block for mortar prisms, elastic straps, carrying case.
Weight: 1000 g approx.

S337-51
CALIBRATION PROCESS of one Extensometer / Compressometer combined with digital unit. The Electronic Universal Extensometers/Compressometers mod. C134 (as well the Compressometer C130N and the Compressometer/Extensometer C133 connected to linear strain transducers, see next page), can be used with:
– Matest compression machines equipped with Cyber-Plus Evolution Touch Screen
– Matest compression machines equipped with Servo-Plus Evolution Touch Screen
The electric cable of the displacement transducer is directly connected to one of the eight channels available on the digital Cyber/Servo Plus unit.
Through the suitable Software (accessory mod. C134-05) the digital unit will automatically elaborate the data, supplying the load/deformation graphic with certificate printing.

C134-05
SOFTWARE for Elastic Modulus test on Concrete and Mortar specimens.
Automatic data and processing acquisition, load/deformation graphic and certificate printing, with direct management of the testing machine, or remote through PC.
This software can be used only with the Cyber/Servo-Plus Evolution systems.
All these Extensometers/Comperssometers can be used with other compression machines, also from other producers, by connecting them to the semiautomatic data
acquisition system:

S335N
CYBER-PLUS EVOLUTION 8 CHANNELS TOUCH SCREEN UNIT
It measures both the extensometer’s deformations and the applied load to the sample with graphic simultaneous display up to 3 sizes (ex.: load, deformation, time etc.) with all data storage and unlimited memory.
