Figure 1: Schematic diagram of a sensor transmission line in an industrial environment

Summary This article shows the challenges an extended IoT system can pose in terms of EMC and thus also functionally. Potential leakage currents, inductively and capacitively coupled interference can disrupt data transmissions from wired sensors. To reduce these influences, decoupled, i.e., galvanically isolated

Figure 1: Emerson Rosemount's 3051S series wireless instrumentation exemplifies the benefits WSN brings to industrial applications: It can reduce total installation costs by 45% and total deployment time by as much as 75%, eliminating design and installation time and cost associated with wiring, conduit, cable trays, and junction boxes.

Wireless sensing is the most important new technology in process measurement to appear in decades. For this reason alone, it has attracted the sustained attention of ARC Advisory Group and other industry
