What is electromagnetic interference?

Electromagnetic interference is abbreviated as EMI. EMI is the disturbance which is unintentionally generated by an external source that effects the electrical circuit by electromagnetic induction, electrostatic coupling or conduction. This is a particular problem with sensitive equipment where transmission signals may be corrupted or distorted. Data transmission may also result in an increase in error rate or total loss of data.

Disturbance generated by external source effects the electrical circuit by electromagnetic induction, electrostatic coupling or conduction.

Electromagnetic interference can be reduced by ensuring that all electronic equipment is operated with a good electrical grounding system. Cables used to connect the electronic or computer systems should if possible be shielded such as the CY control cable or our range of instrumentation cables. The use of specialised components and circuits to reduce EMI through the use of filters, capacitors and inductors can also be installed in the circuit path.
