Chair comprehensive tester, in the same test machine can carry out a variety of tests of the chair, the user can complete the mechanical properties of the chair seat, the back of the chair, the armrest, both sides and other parts of the chair through simple and quick adjustment. By the PLC controller with LCD touch screen for parameter setting, can set the test force value, pressure holding and cycle time, reach the specified force value, automatic timing, automatic return time.
Features of Chair Comprehensive Tester
Hardware features
1. The force application device is guided by a roller, and the instrument runs smoothly
2. The cylinder is equipped with a noise reduction device, so that the test data can reduce the sound of the instrument operation on the basis of ensuring accuracy;
3. The cylinder is provided with a stroke limit, which fixes the stroke of the cylinder rising and falling;
4, the base of this product is combined with high-quality carbon steel plate and high-strength aluminum alloy profile, without drilling fixed on the ground, fully ensure the stability of the instrument operation;
5, equipment short circuit protection, to avoid excessive short circuit current to overheat electrical equipment or be damaged by electric power.
Software feature
1, the control mode adopts PLC programmable controller, effectively avoid circuit board, servo drive and other interference to the test data, the language is optional English, Chinese, intuitive and convenient operation, can complete the test parameter setting, working state control, data acquisition and result display;
2. Power off protection of the instrument, save the current test data instantly when the power is off. When the next power is used, you can view the last test data or continue the test;
3. The number of experiments can be arbitrarily set at 1-999999 times. After reaching the set number, the machine will automatically stop, and the test will be completed or the sample will be damaged in other cases.
