Isolate the noise, not the signal
Isolators and signal converters are most often used on 4-20 mA loops, where a 24 Vdc power source provides power to a field instrument. The instrument returns a 4-20 mA signal that typically represents a measurement, such as flow, level, pressure, etc. Isolators can be introduced into the “loop” to solve simple problems such as ground loops or noise.

Process control instrumentation: Advanced applications for isolators and signal converters
Isolators can be used for many applications in process control beyond just eliminating ground loops and conditioning signals. In Part 2 of this exclusive two-part series, Greg Feliks of Moore Industries presents a selection of advanced applications for isolators and signal converters.
