scope of application:

The fully automatic rebar elongation tester integrates a machine vision intelligent measurement system, which can automatically identify the characteristics of rebar markings, extract the actual distance of the markings, and calculate the rebar elongation. It meets the requirements of GB 1499.1-2024 "Reinforced Concrete Steel-Part 1: Hot-rolled Smooth Rebar", GB 1499.2-2024 "Reinforced Concrete Steel-Part 2: Hot-rolled Ribbed Rebar", and GB/T 228.1—2021 "Metal Materials-Tensile Testing-Part 1: Room Temperature Test Method".

Performance features:

1．Integrated industrial digital camera, high definition imaging quality, accurate displacement measurement

2．Integrating machine vision module, intelligent recognition of steel bar break point, clamping point, engraved mark

3．Integrated step drive system, automatic focus on the upper surface of the steel bar when taking photos

4．Integrated industrial touch screen computer, reliable operating system, rich equipment resources

5．The independent research and development of online software, the human-machine interface is simple, the test parameters are perfect

6．Integration of automation concepts: automatic identification of engraving lines, calculation of elongation, record preservation, data upload
