There are three following factors that affect the operation of the electronic tensile testing machine :
1. Unstable power supply conditions
There are many high-power devices, and the start or stop of large inductive loads will cause grid voltage fluctuations. Therefore, the overvoltage or undervoltage of the grid voltage reaches ±15% of the rated voltage, and a spike interference control system occurs, which affects the accuracy of the measurement and control system.
2, serious noise pollution
In the more complex system, the electronic tensile testing machine has many input and output lines and control lines, and often has a long transmission distance, and the interference introduced by it is frequent. If the signal of 0~15V is placed in the casing together with the AC 220V power supply line, mutual interference will be generated by electromagnetic induction between the paths, and a common mode or differential mode voltage will be formed in the channel to make the measured signal occur. Errors, even consuming the useful signals, make the computer not working properly. In addition, there are meteorological conditions from its space, changes in geomagnetic fields, electromagnetic waves, electromagnetic waves from communication launchers, and electromagnetic interference from surrounding electrical equipment. These radiated disturbances can sometimes affect the computer control system and prevent it from working properly.
3. Other environmental pollution
The temperature, humidity, floating dust, corrosive gas, etc. of the surrounding environment of the electronic tensile testing machine will affect the reliability and stability of the computer control system. In summary, in the computer control system, it is necessary to solve the problem of adaptability to the surrounding environment, and take corresponding measures to improve its reliability.
