Tensile testing machine ERT-300

computer-controlledmaterialindustrial

Model ERT-300 Computer Controlled Electronic Relaxation Testing Machine is designed for the relaxation tests of PC Steel bar, Steel wires, indented wire, and galvanized Steel wire etc. This machine adopts vertical load frame with great rigidity, AC servomotor with zéro clearance & great torque précisé reducer to drive the screw to carry out the adjustment of the test space, the tension of specimen and keeping of the load force, to complété the relaxation test. The machine is equipped with especially designed industrial PC. The control and data processing System of IPC has very high reliability, which can meet the requirements of data adopting, displaying, storage and data analyzing demanded by the relaxation test that over 1000 hours; Testing standard: ASTM E328, ISO 15630, BS5896, ASTM A1061 etc. a) - Control method: Industrial PC automatically control, arbitrary point position keeping b) - Operation System: Windows 7 or above c) - Extrapolation of results front 100 hrs to 1000 incorporated in the software d) - Recording time interval of data point: 0.1s-72hrs, randomly set e) Max. duration of test: 21000hrs e) - Storage of the data: ASCII text, PC automatically storing Max.
