DTT-500

PC Strand Deflected Tensile Testing Machine

UNIVER DTT-500 PC Strand Deflected Tensile Testing Machine is specially designed for defected tensile test on wire strand according to ISO 15630-3, this test method is to determin the reduction coefficient of the maximum force in uniaxial tension due to a deviation of 20degree around a specified mandrel.

This machine is powered with a servo-hydraulic power pack which controlled through software where testing curves and testing results are automatically obtained, it adopts interchangeable triple wedge anchorage for wire strand of different diameter, this machine also features combined load cell calibration set-up where can get load cell easily calibrated right on the machine

ISO 15630-3: Steel for the reinforcement and prestressing of concrete – Part 11. Deflected tensile test

Features:

Real-time display Load/stress versus time curves
Automatic calculate corresponding value of wire strand under deflected tensile test.
Servo-controlled hydraulic system ensures the high pricision load/displacement/strain close-loop control as well as low noise.
Interchangeable mandrels made of tool steel in high hardness
User configurable test methods and customizable report template.
Self-alignment design on specimen anchorage to ensure the the high accuracy
Transparent window ensure operation safety without sacrifacing visibility
Patent claribration system is mounted on machine to calibrate not only the load cell but also the whole system without disassembly the load cell from machine.
