From Dataforth Corporation
In today's dynamic industrial environments, electronic devices, signal and power wiring, and other electrical plant/process equipment often interact to create "noise" or electromagnetic interference (EMI) problems which can degrade critical measurement and control signals. Proper grounding and shielding techniques can help reduce or eliminate these problems and maintain signal integrity.
Three basic elements are required in order for a noise problem to exist; 1.) a noise source to generate the noise, 2.) a receiving device which is affected by the noise, and 3.) a coupling channel between the source and receptor. The objective in electromagnetic compatibility is to minimize, divert, or eliminate one of the three elements necessary for a noise problem.
