\ August 2016 | industrial automation asiaj WIRELESS PRESSURE GAUGES IAA INTERVIEWED BILL ZHOU, MARKETING DIRECTOR, ROSEMOUNT ASIA PACIFIC, EMERSON, ON THE COMPANY'S WIRELESS PRESSURE GAUGE SOLUTION. BY MARK JOHNSTON Wireless, Pressure Gauge, Process IAA: Late last year, Emerson introduced the world's first WirelessHART pressure gauge. What are the implications of such a development? Bill Zhou (BZ): One of the pain points from our customers who operate refinery or chemical processing plants is the unreliability of the traditional mechanical pressure gauge. Mechanical gauges often have a much shorter lifespan compared to a pressure transmitter and could be a safety risk in high pressure applications. This leads to higher costs associated with frequent replacement of gauges or procuring more durable gauges that can withstand harsher environments. At the root of the problem is the traditional Bourdon tube technology that is prevalent in all mechanical gauges. The company's design of the Rosemount Wireless Pressure Gauge aims at improving reliability and safety issues by eliminating the Bourdon tube and replacing it with our proven solid state pressure sensor. The solid-state pressure sensor is based on the piezoresistive measuring principle and has been employed successfully in pressure transmitters for many decades. As a result of this robust sensor design, the Rosemount Wireless Pressure Gauge is able to handle high vibration environments of up to 3G and withstand up to 11,000 psi of burst pressure. Another challenge that our customers are facing is that the safety of plant personnel may be at risk due to manual rounds which are needed to read and record gauge values. Since the wireless pressure gauge provides an output based on the IEC 62591 standard (WirelessHART), pressure readings, ambient temperature, and even device health status can be sent back to the operating room via wireless. Being able to read gauge values without having to step foot in the plant environment really helps plants to reduce the safety risks to their personnel. IAA: What are some of the challenges associated with pressure gauge development and where do you see the technology of pressure gauge measurement, especially wireless going in the future? BZ: Plants that adopt this technology will benefit from having a much more reliable gauge measurement while also being able to wirelessly collect data from the field. In the future, we believe that wireless

IAA: What were the trade-offs in developing a wireless pressure gauge? BZ: The main trade-off in developing this wireless pressure gauge is the battery life versus update rate. The Rosemount Wireless Pressure Gauge has a battery life of 10 years at an update rate of once per minute. IAA: Does the wireless pressure gauge make possible new applications or use cases that perhaps were not...
