As of December 2009, Emerson Process Management sales offices has sold one million Fieldvue digital valve controllers worldwide. First introduced in 1994, the product and its digital communication and diagnostic capabilities changed the way process control manufacturers monitor control valves and accelerated the process industry’s move to digital instrumentation. By 1999, the installed base of 100,000 instruments had delivered one billion hours of run-time in process plant environments. Over the past decade, the global development team has added numerous enhancements and application options such as a stainless steel version for use in harsh, offshore environments and a remote mount option that can withstand temperatures up to 120C.
