Why use wireless devices in industry?
Manufacturers need to get more out of their plants each year to stay viable, Moss said. Capital investments are decreasing-plants are becoming older and are maintained far beyond their design life instead of being replaced. Staff numbers are run down to reduce costs and increase cost efficiency. At the same time, demands for throughput growth, quality control, and traceability have increased markedly.
"All this means that, each year, plants have to run smarter to survive," Moss said. "Smarter means information, monitoring, and control. New information, online information, and real-time information all involve process transducers, signal cabling, and intelligent systems to receive the transducer signals. Out of these three elements, transducers and systems have decreased in price in real terms over the years. However, the cost of cabling has escalated. Wireless technology can present a cheaper alternative to signal cabling. The choice of wireless will often mean the difference between justifying the cost of an instrument installation or not."
