Touch screen controlled hot wire tester

1、 The testing machine meets the following standards

1. Steel pipe scaffold fasteners GB15831-2006

2. Safety Technical Specification for Coupler type Steel Pipe Scaffolding in Construction JGJ 130-2011

3. Determination of Physical and Mechanical Properties of Ropes GB/T8834-2006

4. Safety Net GB5725-2009

5. Bowl Buckle Steel Pipe Scaffolding GB24911-2010

 

2、 Mechanical structure

This testing machine consists of four pillars and two precision ball screws that fix the upper crossbeam and worktable. It uses an AC servo motor and driver to drive two pairs of high-precision, gapless precision screws through a synchronous toothed belt to move the middle crossbeam up and down. It has the characteristics of reasonable structure, high rigidity, stable loading, and good stability performance.

 

3、 Technical specifications of testing machine

1. The force sensor is a wheel amplitude tension and compression sensor, with an accuracy of 0.05% FS. The system's force measurement accuracy is within the range of 2% to 100% FS, with a relative accuracy of up to ± 1%.

2. Electronic extensometer, with an accuracy of Class C, can measure deformation with a relative accuracy of up to ± 0.5% in the range of 2% -100% FS. (Customers can choose according to the elongation of the material)

3. The displacement sensor adopts a 2000 channel/turn photoelectric encoder and adopts 4x technology to achieve a resolution of 2400 channels/turn (with a maximum resolution of 0.01mm).

4. The deformation measurement adopts an electronic extensometer produced by Beijing Iron and Steel Institute, with a maximum resolution of 0.01mm.

5. The measurement and control system adopts the AD800 testing machine measurement and control system, with the following main indicators:

1) Three analog input channels are used for force value and electronic extensometer measurement, with an AD conversion code of ± 120000 (non segmented measurement achieved with high-resolution AD converter is better than 4-stage amplification).

2) A digital output channel with a 1:100 speed ratio, used to control the servo system for stepless speed regulation within the range of 2-200mm/min.

3) Three optoelectronic coding input channels are used for measuring large deformations and displacements, using quadruple technology to improve measurement resolution.

4) A manual operation box with 8 buttons.
