Emerson sells over one million Fisher digital valve controllers
Danny Nelson, vice president of instruments for the Fisher division, was a mechanical test engineer in the mid-1990s, supporting the new FieldVue instrument design. “From the early inception of the product, we focused on Fisher core product values—reliability and performance,” he said. “Because the FieldVue instrument was the first communicating, loop-powered digital positioner, several new tests were developed to verify technologies deployed in the product. These were never done before in prior valve mounted instrument products.”
With its introduction, the FieldVue instrument platform not only received several industry awards, but also resulted in more than 50 patents for its innovation and reliability. By 1999, the installed base of 100,000 FieldVue DVC5000 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 for FieldVue instruments, from online diagnostics to remote mounting. Emerson personnel developed a stainless steel version for use in harsh, off-shore environments as well as a remote mount option that can withstand temperatures up to 120 °C (250 °F).
