Universal Testing Machine 50 KN

Universal Testing Machine 50 KN is an industrial design electro-mechanical testing machine with a capacity of 50 kN in traction and compression, adapted for the particular needs of engineering colleges, research and quality control. Tests may be carried out as a function of speed, stress or strain.

The analogue/digital interface and the software provided with the EM550 form a complete package allowing control, data acquisition and analysis using a PC. The advanced, user-friendly software is presented in toolbox form that demands no particular programming knowledge.
Data analysis and presentation can be effected off-line. Data from current and previous runs may be transferred as ASCII files for use with spreadsheet and other software.

Teaching objectives

The universal test machine allows a wide range of tests, including :

Tension, compression and bending.
Standard specimen testing.
Cycling up to 1 Hz.
Creep testing.
Fretting and fatigue.
Assembly and structure tests
