24End-User Field Trials – Dan Crainer & Oxea Puffer-Sweiven account manager for Fisher Controls products at Oxea, Bay City Location.Oxea operations:Oxea Chemicals, Bay City Site is the largest production facility in North America. The site produces wide range of Oxo intermediates and derivative products.Emerson Wireless at Oxea:Oxea has installed Emerson Wireless products in one production unit and has several additional projects in different stages of execution.Vibration Energy Harvester – Value Proposition:The “Vibration Energy Harvester” allows for use of wireless field instruments with lower cost power supply than standard Emerson power module.BenefitsAlternate power options vs. batteries onlyFaster update rates while minimizing/eliminating battery changesReduced overall maintenance logistics & costs
26Sherri Law Senior Instrument & Electrical Engineer - Oxea Oxea Quotes:“Vibration Energy Harvesting offers Oxea a cost effective way to utilize the fastest update rates available on any wireless instrument we choose without the costs and maintenance logistics of frequent battery replacements. This is an obvious aid in process optimization and we see it as the next step towards wireless control”.“Low maintenance costs are critical to the operations of a small facility with limited resources. Vibration Energy Harvesting is seen as a means to reduce maintenance costs due to fewer battery replacements, reduction in stock and lower battery disposal costs. These benefits will also increase as we consider new uses for wireless devices in more remote plant locations”.Sherri Law Senior Instrument & Electrical Engineer - Oxea
28End-User Field Trials – Tim Bonnin & Firestone Polymer Senior Instrument Representative; Beaumont, TXFirestone Polymer operations:Firestone Polymers supplies synthetic rubber, thermoplastic elastomers and impact modifiers to rubber, plastics, adhesive and asphalt markets around the worldEmerson Wireless at Firestone PolymerFirestone was an early adapter of Wireless HART. They have employed WiHart devices throughout the plant and continue to look to wireless instruments as reliable and inexpensive monitoring solutionsVibration Energy Harvester – Value PropositionThe Vibration Energy Harvesters have performed exactly as advertised. The Harvesters has been a welcomed addition to the wireless network that is established at Firestone and gives greater confidence that signal loss due to power interruption will not be a problem. Faster update rates while minimizing/eliminating battery changes is a huge positive for Firestone. The use of the Vibration Energy Harvester should result in reduced overall maintenance logistics and costs
30Firestone Polymer Quotes: “Firestone Polymers has benefited from being one of the facilities chosen to host the beta testing of Perpetuum Vibration Energy Harvesters”. “We have learned that the concept is useful in more ways than one”.“The cost savings that are realized by eliminating the continued purchase and replacement of batteries for wireless instruments”.“Harvesting technology can lead to an even greater reduction in cost for the prioritized wireless instruments in our facility. These instruments require the fastest update rates”.“Fast update rates drastically reduce battery life, it would be prudent to target these wireless instruments as a first justification toward putting this technology to work for our benefit”.Christopher Julian Senior Instrument & Electrical Engineer - Firestone Polymer
