Rosemount, a division of Emerson Process Management, is a worldwide leader
in the manufacturing of instrumentation and automation systems for
industrial automation and process control.
In temperature measurement, the company is the leading manufacturer
of temperature transmitters in the Americas, and is also a manufacturer of
RTDs and thermocouples. The
company, which was founded in 1956, is based in Chanhassen, Minnesota.
formation of Rosemount is linked to temperature measurement.
Dr. Frank D. Werner, an inventor and scientist, was researching
temperature and pressure sensors at the University of Minnesota when the U.
S. Air Force asked him to manufacture the temperature sensors he had
created for some high-performance airplanes.
Werner asked Vernon Heath, a business manager, and Robert Koppel, an
engineer, to work with him in the project.
The three started Rosemount Engineering Company in 1956, using
$8,000 in seed money. They
produced their first sensors in an old chicken hatchery.
original Rosemount temperature sensors could measure the heat generated by
compression during high-speed flights.
This made it possible to measure aircraft speed accurately during
flight for the first time. The
new company generated almost $200,000 in sales in its second year.
After the launching of Sputnik I in 1957, Rosemountís sensors were
in demand for deep space applications.
Company revenues increased to $5.6 million by 1963.
During the 1960s, Rosemount continued selling its sensors to
high-performance aircraft and the space program.
By the end of the decade, sales had increased to $8.5 million.
Heath succeeded Werner as president of Rosemount in 1968.
The company then became involved in several unsuccessful
enterprises, one of which involved the manufacturing of a ski boot line.
Another involved an effort to develop a public rapid transit system.
These two projects together cost the company about $3 million.
At the same time, Rosemount began increasing its industrial sales,
especially in temperature and pressure transmitters.
Rosemount began applying its space and defense technology to
applications in the aerospace, refining, and nuclear and electric power
industries. Industrial sales
kept growing in the first half of the 1970s.
Emerson Electric purchased Rosemount for $54 per share.
At the time, Emerson Electric was a $4 billion conglomerate.
Rosemountís sales continued to grow, exceeding $250 million in
1983. Four instrument
divisions were consolidated in 1987 into the Rosemount Measurement and
Control Instrumentation Group. By
1988, revenues reached $500 million. In
1993, Emerson Electric purchased Fisher Controls International for $1.25
billion. This acquisition
served as the basis for the subsequent creation of Fisher-Rosemount.
Fisher Controls is a leading supplier of valves to industrial
markets. Emerson sold the
Aerospace Division to B. F. Goodrich in 1993 for $300 million.
continues to strengthen its technological leadership, especially in the
areas of pressure transmitters, temperature transmitters, and flowmeters.
The company has dedicated substantial resources toward developing
Foundation Fieldbus products. The
effort to develop a universal fieldbus to connect instruments to the
control room began in 1985.
