While technological innovation proceeds ever faster, a more than 160-year-old technology is still used for pressure measurement today. The Bourdon tube developed by Eugene Bourdon in 1849 is still the most common method for mechanical pressure measurement in the oil and gas industry. Bourdon tubes have different dimensions depending on the nominal sizes of the measuring device and the measuring range, and are manufactured from long stainless steel tubes in a bending machine. Welded to the connection piece of the measuring device at one end and to the tube end piece at the other end, the measuring systems are checked for leaks and undergo an overpressure cycle to eliminate tensions in the material. Then they are welded to the pressure gauge housing in an automated laser welding plant, www.baumer.com/bourdon.
