Noise
Noise
(OP)
Hello gentlemen,
How do we determine that an environment is "noisy", particularly when designing a system that is composed of field instruments producing delicate signals? I'm thinking AC machinery and switching devices, but do you take into account any other factors when dealing with instrumentation?
Thank you for your feedback

RE: Noise
Most sensory equipment these days are designed to deal with 50/60Hz noise and so this type of interference and coupling does not greatly affect readings. But, short bursts from switching transients, EMI from variable speed motor systems, cell-phone transmissions, phase-controlled heating, and wireless control systems will all pile-on interference.
