Patent number: 7610795Abstract: A method serves to adjust a mechanical natural frequency of a hollow body which at least partly comprises a ductile material, in particular a pickup housing of a measurement pickup or a measurement pipe of a measurement pickup. A static external pressure of an atmosphere surrounding the hollow body and/or a static internal pressure prevailing in a lumen of the hollow body, the lumen being sealed off substantially in a pressuretight fashion, is varied in order to generate a pressure difference between the lumen and the atmosphere surrounding the hollow body. The pressure difference is adjusted to a value that causes the material of the hollow body to expand, and at least a proportion of the material of the hollow body is made to flow under the influence of the pressure difference for plastically deforming the material. The method can readily be integrated into already-established pressure tests for measurement pickups of the vibrational type.Type: GrantFiled: September 27, 2004Date of Patent: November 3, 2009Assignee: Endress + Hauser Flowtec AGInventors: Ennio Bitto, Holger Bernhard, Christian Schuetze
