Independent study shows HART as a global leader

26 July 2011

According to a recent market study, undertaken by the ARC Advisory Group, 46% of all field devices installed worldwide at year-end 2010 communicate using the HART Communication Protocol.

This is the largest market share of any field communications protocol, larger than other leading fieldbus devices (Foundation, Profibus and other all-digital), proprietary protocols and 4-20mA (analog/non-smart) combined.

The ARC study estimates that the number of installed HART-communicating devices will grow to 35 million in 2011 and projects growth to continue to 37.3 million in 2012.

“Users worldwide are sending a clear message to industry suppliers by purchasing and deploying HART-enabled products in such numbers,” said Ron Helson, executive director of HART Communication Foundation. “Users choose HART Communication because it is a simple, reliable, secure, low-risk, feature-rich and cost-effective intelligent communication protocol that delivers significant value during the entire plant life-cycle. HART is the field-proven global standard and its use will continue to increase for the foreseeable future.”

The study included a five-year market analysis and technology forecast of pressure transmitters, representing the largest product segment of field devices. The Pressure Transmitter Worldwide Outlook projects that the market for HART-enabled pressure transmitters will continue to grow and is expected to represent nearly 73% of all transmitters shipped this year. A comparison with the 2005 study shows that HART Communication is the only communication technology that significantly increased its share of the pressure transmitter market.
