    9. Other Information General measures when using electronic control systems So that even complicated regulatory tasks can be presented to the user in a manner which is clear and simple and ensures high measurement accuracy, today's electronic control systems make increasing use of microprocessors. However, the benefits of these systems are countered by the disadvantage that increased measurement accu- racy is accompanied by sensitivity to interference.
  • Page 91 9. Other Information General measures when using electronic control systems If specific interference sources cannot be avoided they should at least be kept at a distance from the regulator system. Capacitive and inductive couplings can cause crosstalk between high-voltage lines and parallel low-voltage and sensor lines. This distorts measured values and signals and can disrupt the entire regulatory process.
  • Page 92 9. Other Information General measures when using electronic control systems Semiconductor switches such as thyristors or triacs also produce interference voltages. They occur as a result of non-linear characteristics and finite ignition voltages. These components must be protected against excessive voltages, for which mainly varistors, RC combinations or choke coils are used.
