Wireless is making important maintenance and asset management technologies and techniques more powerful and cost-effective. 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.
“While wireless networking technology offers tremendous potential for providing incremental performance improvements in today’s industrial enterprises, it clearly is not for the faint of heart,” says Cory Welch, practice director, Enterprise Network and Security Services at Invensys Process Systems.
Vendors including Invensys and Honeywell are recognizing and addressing this issue.
Invensys (www.invensys.com) recently introduced seven new wireless-enabled enterprise solutions and expanded implementation and support capabilities. These solutions can be deployed at both plant and enterprise levels to improve overall industrial asset performance management.
Meanwhile, Honeywell (www.honeywell.com/ps/wire less) launched its OneWireless universal industrial wireless mesh network solution. It is said to help improve plant safety, reliability and efficiency with a scalable wireless infrastructure that supports wireless-enabled devices in strategic locations throughout a facility.
Invensys looked for the most-needed and highest-return applications and put together technology, partners and implementation/support services to address each of the seven solutions with an IT-infrastructure approach. Mobile Workforce, for example, gives field employees roaming access to real-time control systems, enterprise applications, documents and other information via wireless handheld devices and hardened Mil Spec and NEMA 4-rated tablet PCs. The Condition Monitoring solution offers a wireless connection to remote sensors to provide incremental measurements like tank levels, temperatures, pH, vibration, etc. for a richer real-time data base to support model-based predictive maintenance strategies.
Scalable to 30,000 devices, Honeywell’s OneWireless supports existing XYR 5000 wireless transmitters and a new line of XYR 6000 transmitters. It also supports wired transmitters, mobile worker devices and standard Wi-Fi and Ethernet clients. An open, standards-based infrastructure lets manufacturers take advantage of new applications as they become available.
Honeywell has implemented field trials of OneWireless at multiple sites, including Nucor Steel Tuscaloosa Inc. in Alabama where the OneWireless network is configured with wireless temperature and pressure sensors to improve efficiency of several steel-manufacturing processes. The pressure sensors, for example, enable operators to measure air filtration system performance and schedule maintenance only as needed.
Nucor also uses the technology in its bag house, a building that filters air from steelmaking to eliminate potentially harmful substances. The differential-pressure transmitters monitor the bags to determine when they need cleaning.
