XJJD-50Digital display simply supported beam impact testing machine
This series of digital impact testing machines is mainly used for measuring the impact toughness of non-metallic materials such as hard plastics, reinforced nylon, fiberglass, ceramics, cast stones, and electrical insulation materials. It is an ideal testing equipment for the chemical industry, research institutions, colleges, quality inspection and other departments.
feature：
1This series of impact testing machines is an intelligent digital impact testing machine developed and produced using microcomputer technology. The advanced feature is that it can automatically correct the energy loss caused by friction and wind resistance, eliminating the need for numerical charts that correct energy due to the influence of resistance. The detection of residual energy and correction of energy loss of the pendulum after sample fracture is completed in one go during the impact process.
2This series of impact testing machines all usePLCcontrolLCDThe LCD text display displays the test results, making the reading more intuitive and improving the accuracy and precision of the impact machine. The Chinese character finger icon operation is simple and clear.
3The sensor used in this instrument is a split type floppy disk high-precision encoder with high accuracy and low failure rate; The hanging hammer electromagnet is a customized integrated electromagnet with reliable connection, low noise, safe and reliable operation.
XJJDThe main technical parameters of the series of simply supported beam impact testing machines fully comply withIS0 179、GB/T 1043、JB／T 8762 Regulations of Standard Huai
