Electrical noise is a phenomenon typical of industrial environments. The following are guide-
lines that must be followed to minimize the effect of noise upon any instrumentation.
2.5.1.1 INSTALLATION CONSIDERATIONS
Listed below are some of the common sources of electrical noise in the industrial environment:
• Ignition Transformers
• Arc Welders
• Mechanical contact relay(s)
• Solenoids
Before using any instrument near the devices listed, the instructions below should be followed:
1. If the instrument is to be mounted in the same panel as any of the listed devices, separate
