Rugged Pumps for Industry need to rationalize comments,” says Helson. That will lead to a framework for companies to build products, he adds. “You’ll probably start to see WirelessHART-enabled products in early 2008.” Helson anticipates that one early and important device will be an addon, “a slap-on,” for existing wired HART devices to “establish a new wireless path to asset-managementtype applications without disturbing the 4–20 mA signal.” Then there’ll be gateways, he expects. “Pepperl+Fuchs has released working prototypes of a HART gateway (Figure 1),” Schosker notes, adding this doesn’t represent a shift in the company’s strategy. “WirelessHART gives us just another tool to help our customers and find a solution to their need.” Emerson will broaden the role of PlantWeb, a real-time control-and-asset-management architecture, Zielinski says. ABB will continue to develop selfand outside-powered wireless devices — process transmitters — for instrumentation and others for condition monitoring, Johnston notes. Suggesting silicon’s availability will affect product releases, he reckons “product to be available early 2008.” Invensys “has supported HART for quite a while and will continue to support HART as wireless communications,” comments Brian Courchesne, marketing manager with Invensys Performance Services, Foxboro, Mass. Yokogawa is looking at WirelessHART sensors, environmental sensors that differ from existing process monitoring sensors and gateways, Smith says. Siemens has exhibited WirelessHART demonstration field devices at the 2006 ISA Expo and 2007 Interkama shows (Figure 2). “It seems so far that customers are interested in getting some more experience with the new technology, step by step,” Stephan notes. “Honeywell will offer WirelessHART, if customers request it, of which we have seen little indication of this to date,” Becker says. Besides new products, education is important to the protocol’s success. Zielinski points to the inevitable learning curve and the need to share insights. “The information the buy-it-and-try-it people [will] have learned and their confidence in WirelessHART has to become common knowledge across the board.” Helson agrees. “We’re going to need to educate users, to overcome their fears and concerns about wirelessenabled field devices.” Even end-users who think they’re familiar with HART should “take another look,” advises Shear. Untethered prospects Weiss counsels the curious to try WirelessHART. “If it sounds too good to be true, it is true here.” She also encourages those who used wireless years ago and said it didn’t work very well to try wireless again. “It’ll be a new experience. Try it, you’ll like it.” Becker says the “big promise of wireless is to simply make the plant more safe, efficient and reliable. It is an enabling technology that opens many new doors.” Helson, with WirelessHART specifically in mind, certainly agrees. “It will open a lot of new doors, to help [companies] run their plant better, to keep their plant competitive.” CP • Reliable • Corrosion-Resistant Your special requirements welcome Ceramic/Hastelloy® Process Pumps for Highly Corrosive Gases Gas-Tight, Double-Diaphragm Safety Pumps & Compressors Group C&D, ATEX Explosion-Proof Pumps >> Field devices ISO 9001:2000 CERTIFIED Programmable, Insulated-Jacket 460°F Heated-Head Sampling • Heated-head sampling pumps • Double-diaphragm safety pumps • Explosion-proof pumps - group C&D or ATEX • Clean, oil-free, contamination-free transfer • Flow to 10 SCFM, 29 in.
