XJSC-300 Steel Strand Tensile Stress Relaxation Testing Machine

Product Information

The XJSC-300 type steel strand tensile stress relaxation testing machine is designed based on GB/T5224-2003 "Steel Strand for Prestressed Concrete" and GB/T10120-2013 "Metal Stress Relaxation Test Method". The design of the main unit and auxiliary equipment of the testing machine draws on advanced technologies from both domestic and foreign sources, with a beautiful appearance, easy operation, and stable and reliable performance. The computer system uses a fully digital controller to control the servo motor rotation through a speed regulation system. After being slowed down by a deceleration system, it drives the screw to move and complete the experiment. It is pollution-free, low-noise, stable and reliable. Randomly equipped with computer and experimental software, with a beautiful interface and easy operation; The test force and deformation display are eye-catching; Embedded database for easy data history tracing and networking requirements; The report is operated using templates, and users only need simple training to master it. The entire software has strong encapsulation, easy operation, and comprehensive functions; According to the set test parameters, the control, data acquisition, display, and storage of the test process can be automatically completed (main parameters: test force, relaxation force, relaxation rate or logarithmic relaxation rate, temperature). After the test is completed, the data can be analyzed and processed, and the test curve and report required by the user can be printed and output.

Product Features:

1. Display the relationship curve between residual test force or relaxation rate and time, as well as the temperature time curve.

2. The stress relaxation performance of the specimen can be calculated for 1000 hours.

3. The loading speed can be set according to displacement or force value.

4. The load and displacement are calibrated using digital methods.
