Today, Bourdon® is one of the world leading brands for mechanical process instrumentation and belongs with its international business locations to the Baumer Group. It was created in 2005 by the acquisition of the service portfolios and competences of the formerly well-known brands Bourdon-Sedeme and Haenni. Historically, this competence and passion is based on the Bourdon tube invented in 1835 by Eugène Bourdon, which is the central component for precise mechanical pressure measurement technology, today and in the future. The comprehensive product portfolio is manufactured with high vertical integration and state-of-the-art process methods in the company own production sites in France, Switzerland, Germany and India. In addition to the standard products such as thermometers, pressure gauges, pressure and temperature switches and diaphragm seals, this portfolio also comprises a large number of customer-specific solutions, which are mainly used in the sectors of oil and gas, energy / power plants, water supply, chemistry as well as heating, ventilation and air conditioning. A worldwide distribution network with specialized Bourdon distributors and Baumer’s own subsidiaries provides fast and reliable customer service with high product availability thanks to local presence.
