| Abstract |
Most components of automatic systems used in industrial process control are standard programmable microelectronics systems, and their malfunction may affect operator safety. The purpose of this study was to analyze the level of immunity of certain components to radiated interference. One programmable industrial controller, 2 sensors (pressure and temperature), one regulator and 3 microprocessors were tested using a measuring method comparable to the standard method. The results show that even if immunity is taken into account at the design stage, malfunctions still occur when the level of interference exceeds the immunity threshold specified by relevant standards, which can sometimes happen in the industrial environment. |
