Publication number: 20120067131Abstract: A construction concept for high-pressure sensors is provided, enabling simple and economical manufacture of reliable high-pressure sensors even for pressure ranges above 2200 bar. A high-pressure sensor of this kind encompasses a sensor element for pressure sensing and a connector piece for coupling the sensor element to a measured system, a diaphragm being embodied over a blind opening in the base element of the sensor element, a pressure conduit being embodied in the base element of the connector piece, and the sensor element being mounted on the connector piece in such a way that the diaphragm can be impinged upon, through the pressure conduit that opens into the blind opening, by a measured pressure. The blind opening in the base element of the sensor element is embodied, at least in one portion, in a manner tapering conically toward the diaphragm, and that end of the pressure conduit which faces toward the sensor element is tubular in shape.Type: ApplicationFiled: March 12, 2010Publication date: March 22, 2012Inventors: Thomas Moelkner, Wilhelm Frey

Publication number: 20070263700Abstract: A method for pressure-independent temperature determination using a metal diaphragm is provided. A bridge circuit having multiple resistors is provided on this diaphragm. One pair of resistors is near the center of the diaphragm and another pair of resistors is situated at a distance from the center. The resistors are provided on the metal diaphragm in such a way that the tensile elongation of the pair of resistors near the center corresponds in absolute value to compressions of the pair of resistors far from the center.Type: ApplicationFiled: November 19, 2004Publication date: November 15, 2007Inventors: Thomas Moelkner, Carsten Kaschube, Hans-Peter Didra, Michael Kott

Patent number: 7159448Abstract: A pressure sensor for measuring the pressure in a space acted upon by high pressure. The signals detected by the pressure sensor are supplied to evaluation electronics. A sensor diaphragm is accommodated on the end of the pressure sensor pointing towards the space acted upon by high pressure. The sensor diaphragm takes the form of a steel diaphragm, to whose back side a thin, metallic layer accommodating piezoresistive measuring elements is applied. The thin, metallic layer is contacted by transmission elements and connected to the evaluation electronics.Type: GrantFiled: July 22, 2004Date of Patent: January 9, 2007Assignee: Robert Bosch GmbHInventors: Thomas Moelkner, Holger Scholzen, Joerg Gebers, Ralf Kaiser, Carsten Kaschube, Christian Roesser, Lothar Baumann, Hans-Peter Didra, Roger Frehoff, Markus Fissler, Markus Ledermann, Benjamin Thiel

Patent number: 7040172Abstract: A micromechanical pressure sensor and a method for producing a micromechanical pressure sensor. This pressure sensor has at least one membrane and a measuring element situated on the membrane. A pressure applied at the membrane or a pressure differential applied at the different sides of the membrane results in deformation of the membrane. Simultaneous with the deformation of the membrane, the measuring element is subjected to elastic elongation and/or compression. In a piezo-sensitive component, such elastic elongation and/or compression generates a measured variable in the measuring element, which represents the applied pressure or the applied pressure differential at the membrane. It is provided in this context that the measuring element have at least partially a NiCr(Si) layer. Due to an at least partial crystallization in the production of the micromechanical pressure sensor, this NiCr(Si) layer has more advantageous piezoelectrical characteristics than an amorphous NiCr(Si) layer.Type: GrantFiled: February 16, 2005Date of Patent: May 9, 2006Assignee: Robert Bosch GmbHInventors: Thomas Moelkner, Ralf Henn, Werner Steiner, Hans-Peter Didra, Philip Cutuli, Frank Klopf

Publication number: 20050126297Abstract: The present invention relates to a sensor element for detecting pressures or forces. The sensor element (10) includes a sensor diaphragm (13), on the diaphragm outer side (20) of which piezoresistive measuring elements (8) are located. The sensor diaphragm (13) of the sensor element (10) is diametrically opposed to a sealing surface (15, 16) for sealing off the sensor element (10) from a housing. A force introduction region (23, 24) for introducing a force which produces a seal is mechanically decoupled from the sensor diaphragm (13) of the sensor element (10).Type: ApplicationFiled: July 15, 2004Publication date: June 16, 2005Inventors: Thomas Moelkner, Holger Scholzen, Joerg Gebers, Ralf Kaiser, Carsten Kaschube, Christian Roesser, Lothar Baumann, Hans-Peter Didra, Roger Frehoff, Markus Fissler, Markus Ledermann, Benjamin Thiel
