Microcomputer controlled stress relaxation testing machine
Current Category: Non-standard products
Features:
Horizontal four column, high rigidity, high stability, no vibration impact, streamlined load rack, rack size can be customized.
The system uses imported servo motors as power sources and has force closed-loop and displacement closed-loop control functions;
In case of special events during the experiment (such as power outage, computer freeze, etc.), the servo motor braking system will be activated to ensure that the target value remains unchanged; The software automatically saves data, and the experiment can continue after the event is resolved.
There are two testing methods: displacement holding and deformation holding. The deformation sensor adopts high-precision grating displacement sensor, which has high accuracy and good stability;
The system can collect temperature values from up to three temperature sensors and display and record them in real-time on the measurement and control software;
Process reproduction and data reanalysis, curve amplification, comparison, traversal, and multi curve stacking; The curve can be freely enlarged and reduced; Full degree self adjustment;
Real time display of the relationship curve between residual test force or relaxation rate and time during the experimental process.
Built in Ethernet interface; Convenient handheld controller with stop and go function; Flexible operation and free switching
Automatically calculate the stress relaxation performance (such as stress relaxation rate) of the specimen and print out the complete test report.
Chinese standard data calculation: For a test period of ≥ 120 hours, calculate the stress relaxation performance for 1000 hours. The calculation methods include double logarithmic and single logarithmic options, and the calculation data includes all data and corresponding data options for characteristic time points; The testing time can be set according to different requirements
Real time drawing of residual test force temperature, force relaxation rate, force displacement deformation and other curves.
Multiple protection functions: test force overload protection; Overcurrent and overvoltage protection; Safety protection during sample breakage; Automatic protection after the end of the experiment, etc;
Network database management, able to directly connect with multiple networked companies
