Energy cost control is not a one-time event, and it takes more than one tool to make progress. A number of people, both internal and external to an industrial facility, can contribute to effective energy management.
Last months ISA Expo in Houston clearly showed how much attention wireless technology is attracting. However, concern about the reliability and life of batteries remains an issue. Thats why harvested or scavenged power is attracting interest.
For maintenance and condition-monitoring, wireless technology offers much more than just reducing or eliminating costs. However, wireless also requires an integrated infrastructure approach rather than independent, proprietary point solutions.
