General description
General description
Introduction
The UTM Series are versatile machines which satisfy the requirement of Central and Commercial laboratories for tensile tests under load/elongation control on steel re-bars, rounds and flats and for general compression, flexural and tension tests on various materials.

Description
The machine consist essentially of a robust two column frame with an upper crosshead which can be adjusted in height and of a lower mobile crosshead moved by an electromechanical system with a single recirculating ball screw , powered by a DC permanent magnet servomotor which assures smooth application of load at a constant speed.
The stress is measured by a load cell incorporated in the upper crosshead and the displacement by an encoder fit to the DC motor. The advanced microprocessor technology achieves a large flexibility in conducting the test. The menu driven program gives the operator the possibility of performing the test under load, elongation and displacement control.
The machine is supplied complete with high precision load cell. PC and printer, gripping systems, platens, extensometers and other accessories are not included and have to be ordered separately. See accessories
