General description
General description
This machine has been designed for use, in the field or laboratory to perform tension tests on steel rebars up to 26 mm dia. and compression tests on cylindrical concrete specimens up to dia. 160x320 mm and cubes up to 150 mm, using the appropriate accessories. 
Load measurement and data acquisition by the DIGIMAX UTM microprocessor digital display and processing unit.

The frame consists of a very rigid frame with double acting cylinder assembly.

It includes a set of tensile holders, 4 wedge grips for flats up to thickness of 13 mm, 4  wedge grips for rounds up to 26 mm dia. and 2 sets of grips' liners 4 and 8 mm thick.

Spherical seat and compression platens for concrete specimens are not included and have to be ordered separately (see Accessories).

High precision displacement transducer, 150mm travel, can be mounted (as accessory) on the piston/cylinder assembly to obtain stress/elongation graph based on the crossheads separation measurement.

DIGIMAX UTM digital display and processing unit
The machine is fit with Digimax UTM, microprocessor digital system with large graphic display 240x128 pixel. For elongation measurements it shall be connected to the electronic extensometers (Coaxial or Universal, See Accessoires) directly mounted on the specimen and/or to the high precision displacement tranducer mounted on the frame for grips separation measurement (see Accessories)
Easy connection by Ethernet cable to PC using UTS Light software to obtain the stress/elongation graph and test results complete elaboration conforming to EN Standard. See Accessories

Hydraulic power pump
The power system consists of a dual-stage pump: low pressure/high delivery for fast piston approach and high pressure/low volume for loading. It is optimised to prevent any overheating effects even under intensive use and severe working conditions.
A special flow control valve allows the rate of loading to be pre-set conforming to specifications.

Distance pieces
Made of steel, these pieces are used to reduce the vertical clearance of the compression machine to a height that is appropriate for the size of the specimen and considering that, in general, the maximum piston travel is 150mm.
