While the wheel of innovation turns faster and faster in the process industry, a more than 160-year-old technology is still used for pressure measurement today. The "Bourdon tube" developed by Eugène Bourdon in 1849 and named after him is still the most common method for mechanical pressure measurement.
For more than 160 years, the name Bourdon has established at international level as a synonym for mechanical pressure measurement. In the year 2005, the Bourdon Haenni company became a member of the Baumer Group.
2016 the Baumer Group consolidated the segment of mechanical process instrumentation under the new brand name Bourdon®.
