Deflection Tensile Testing Machine - Servo Hydraulic TT-DTT500-PCStrand

Torontech’s TT-DTT500-PCStrand Deflection Testing Machine is designed for deflected tensile test on wire strand according to ISO 15630-3, this test method is used to determine the reduction coefficient of the maximum force in uniaxial tension due to deviation of 20o around a mandrel.

TT-DTT500-PCStrand is powered with a servo-hydraulic power pack which is controlled with a software for obtaining testing curves and results. Interchangeable triple wedge anchorage for wire strand of different diameters. Calibration of load cell directly done on the machine with load cell calibration set-up.

Real time display of Load/Stress versus Time/Displacement/Strain curves. Automatic calculation corresponding values of wire strand under deflection tensile test. Servo controlled hydraulic system ensures the high precision Load/displacement/Strain close-loop control as well as low noise.

Interchangeable Mandrels made of tool steel in high hardness. Option of customizing your own test configurations. Self-alignment design on specimen anchorage to ensure high accuracy. Transparent window ensuring operational safety. Patent calibration system is mounted on machine to calibrate not only the load cell but also the whole system without disassembling the load cell from machine.
