Description

Introduction
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. 
The system includes the UTM AUTO Power and Control System (PCS) for the automatic execution of compression and tensile tests. 

Frame
The frame consists of a very rigid structure with double acting cylinder assembly.
It includes tensile grips and it is fitted with a 150 mm travel high precision displacement transducer allow­ing test execution under cross­head separation control. See Technical Specifications.

The machine is supplied complete with a set of tensile holders, 4 wedge grips for flats up to 13 mm thickness, 4  wedge grips for rounds up to 26 mm dia. and 2 sets of grip 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).

UTM AUTO Power and Control System (PCS)
Automatically performs steel tensile and concrete compression tests when connected to the relevant accessories. See Technical specifications.
The UTS Light software (included) is tailored for tensile tests according to EN 6892-1 (method B) and EN 15630-1, being suitable for data acquisition and test results elaboration. See Technical Specifications.
