Rosemount Engineering Co
of Durban Road, Bognor Regis, Sussex, process control instruments
British subsidiary of an American company
Dr. Frank D. Werner was working in temperature and pressure sensor research at The Rosemount Research Center at the University of Minnesota when the U.S. Air Force asked him to manufacture the temperature sensors he had developed for their high-performance aircraft. Werner asked Robert E. Keppel, an engineer at the aeronautical lab., and Vernon H. Heath, the business manager, to join him in the part-time project. With $8,000 in seed money the men incorporated Rosemount Engineering Company in 1956.[1]
Rosemount Engineering was a custom business in those days. The government supplied the company with sensor specifications, and Rosemount would fabricate them. Nearly all its sensors were used in aircraft and missiles. Its products were technologically advanced and produced at low volumes and high labour cost. In the late 1960s, in order to reduce its dependency on the U.S. space and defence programs, it moved into temperature and pressure measurement instruments for the industrial market and roadened its operations to include Switzerland, West Germany, Britain, France, Denmark, Canada, and Japan.
