Patent number: 8770032Abstract: A relative pressure sensor includes: a pressure measuring transducer having a measuring membrane of a semiconductor chip and a platform, wherein, between both of these, a reference pressure chamber is formed; a support body, connected with the platform by means of a pressure-bearing adhesion, wherein a reference pressure path extends through the two former elements into the reference pressure chamber; and a sensor outer body, in which a transducer chamber with a first opening and a second opening is formed. The pressure measuring transducer is brought into the transducer chamber through the first opening, and is held therein by means of the support body. The support body pressure-tightly seals the first opening, and a side of the measuring membrane facing away from the reference pressure chamber is contactable with the media pressure through the second opening.Type: GrantFiled: July 21, 2010Date of Patent: July 8, 2014Assignee: Endress + Hauser GmbH +Co. KGInventors: Olaf Krusemark, Norbert Gill

Patent number: 8511151Abstract: A pressure sensor, comprising: a semiconductor pressure measuring transducer having a measuring membrane and a circuit for transducing a deformation of the measuring membrane into a signal; a pressure transfer structure having a hydraulic path, which extends through a solid body between a first a second opening. The first opening is sealed by an isolating diaphragm, which is contactable with a pressure, in order to introduce the pressure to be measured into the hydraulic path. The hydraulic path opens, at the second opening, into a transducer chamber, in which the pressure measuring transducer is arranged and which is sealed by the measuring membrane of the pressure measuring transducer. The hydraulic path contains a transfer liquid; a filling element, which is arranged in the transducer chamber, in order to fill hollow spaces between metal walls of the transducer chamber and the semiconductor pressure measuring transducer.Type: GrantFiled: February 2, 2010Date of Patent: August 20, 2013Assignee: Endress + Hauser GmbH + Co. KGInventors: Raimund Becher, Ralf Nurnberger, Fred Haker, Olaf Krusemark, Olaf Textor

Patent number: 8490494Abstract: A relative pressure sensor for registering pressure of a medium relative to surrounding atmospheric pressure includes: a pressure measuring cell having a measuring membrane and a platform, wherein pressure of the medium can act on a first side of the measuring membrane facing away from the platform, and wherein the platform has a reference air opening, through which surrounding atmospheric pressure can act on a second side of the measuring membrane facing the platform. A support body, through which a reference air duct extends between a first surface section and a second surface section of the support body is provided, wherein the pressure measuring cell is affixed to the support body with a pressure resistant, bonded adhesive.Type: GrantFiled: August 12, 2009Date of Patent: July 23, 2013Assignee: Endress + Hauser GmbH + Co. KGInventors: Davide Parrotto, Anh Tuan Tham, Frank Passler, Olaf Krusemark, Ulrich Buder

Patent number: 6568244Abstract: A measuring and evaluating device for the analysis of gases is described. The device has an exchangeable gas analyzer, which is of small dimensions. The gas analyzer is a module connected directly from the outside to a central unit, which is likewise of small dimensions and into which at least one evaluating unit and a display unit are integrated. Fitted releasably into the gas analyzer are one or more plates, into which at least one separating channel is respectively integrated. Each gas analyzer is provided with at least one sample injector, which can be connected to at least one separating channel. At least one detector is connected downstream of each separating channel.Type: GrantFiled: March 20, 2001Date of Patent: May 27, 2003Assignee: ABB Research Ltd.Inventors: Dieter Binz, Olaf Krusemark, Uwe Lehmann, Jörg Müller, Albrecht Vogel, Sean Keeping
