20100125425 | METHOD AND SYSTEM FOR DETECTION AND COMPENSATION OF A RAPID TEMPERATURE CHANGE ON A PRESSURE MEASUREMENT CELL - The invention is a method and system for detection and compensation of a rapid change in temperature on a pressure measurement cell, in which a measurement signal proportional to the deflection of a diaphragm is generated by means of a sensor. A reference signal proportional to the deflection of the diaphragm is generated by a second sensor; and, measured values are generated by a microprocessor from the measurement signal while the respective reference values are generated from the reference signal. The reference values are compared with the expected values from a tolerance band, and either a pressure-induced deflection of the diaphragm is detected when there is a correspondence, and the measured values are output as measured values for the measured pressure; or, if there is not a correspondence, a deflection of the diaphragm due to a rapid change in temperature is detected, the measured values are corrected and output. | 05-20-2010 |
20100175476 | VIBRATION SENSOR - The invention is a vibration sensor with a carrying element capable of being set into vibration; a conversion device having a field coil to set and/or tap the carrying element into vibration; an anchor mounted in the field coil; and, a vibration element to transmit the vibrations from the carrying element into/from a surrounding space. The anchor is designed as two parts, having a permanent magnet and a coil core connected to the field coil, with an air gap arranged therebetween and lying in the area of the axial extension of the field coil. The permanent magnet is connected to the carrying element to transmit vibrations; | 07-15-2010 |
20110100129 | MEASURING CELL AND A METHOD OF USE THEREFOR - The present invention is a measuring cell comprising a base body. Layered upon the base body is a measurement membrane having a first measuring element, a measurement device, and an intermediate membrane. The intermediate membrane is arranged between the measurement membrane and the base body, and a second measuring element is arranged thereon. When a pressure force is applied to the cell, the measurement membrane is directed outward and undergoes deformation with respect to the intermediate membrane as well as the base body. The deformation causes the measuring capacitance formed by the measuring electrodes to change according to the pressure applied. | 05-05-2011 |
20110100130 | MEASURING CELL AND A METHOD OF USE THEREFOR - The present invention is a measuring cell with a base body, a measurement membrane which is arranged on the base body, and a measurement device, where a clearance between the measurement membrane and the base body is filled with a fluid which presents an increased heat conductivity (κ) compared to air. | 05-05-2011 |
20120194035 | CONDUCTIVE ADHESIVE BOND ASSEMBLY AND SYSTEM FOR THE SAME - An arrangement consisting of a piezoactuator and a printed circuit board that are connected by at least one adhesive connection, with at least one electrical connection created by an electrically conductive adhesive between a first connection contact on the printed circuit board and between a second connection contact on the piezoactuator, whereby the connection contacts face in the same direction and the adhesive connection takes place through an opening in one of the components. | 08-02-2012 |
20130313084 | VIBRATION LIMIT SWITCH SYSTEM - A vibration limit switch system and related method is provided with a piezoelectric transmitting- and/or receiving unit, in operable connection with a membrane that can be put in oscillation, and a mechanical oscillation arrangement that is coupled to the membrane, whereby the piezoelectric transmitting- and/or receiving unit is adhered directly, or via an adaptation layer by an adhesive layer, to the membrane 4. In this improvement, the adhesive layer between the membrane and the transmitting-and/or receiving unit or the adaptation layer has a thickness in an edge area R which thickness is elevated in comparison to a central area Z. This thickness is arranged in differing geometries and amounts to further improve performance. | 11-28-2013 |
20140055007 | Layout System Consisting of A Piezoactuator and A Flexible Circuit Board and Method for Assembling the Same - A layout arrangement and system consisting of a piezoactuator and a flexible circuit board, with at least one electrical and mechanical connection, produced by an electrically conducting adhesive, between a first connection contact on the circuit board and a second connection contact on the piezoactuator, wherein the connection is led through an opening in the flexible circuit board and wherein the surfaces of the connection contacts that are glued together have an essentially parallel and equally oriented normal vector, and a method for assembling and arranging the same. | 02-27-2014 |
20140333176 | Vibration limit switch - A vibration limit switch with a membrane, which can be set into oscillation, and a drive unit for setting the membrane into oscillation and/or for detecting an oscillation of the membrane, with the drive unit comprising at least one electromagnetic drive and one Piezo-electric drive. | 11-13-2014 |

20090200754 | FLAT GASKET, ESPECIALLY A CYLINDER HEAD GASKET - The invention relates to a flat gasket with a gasket sheet having a plurality of passages. The gasket sheet comprises at least one first sheet metal layer which has at least on one side at least one elongate elevation with an elongate base formed out of the sheet metal layer. The base, under maximum stress occurring during installation of the gasket and in machine operation, is stable with respect to the height thereof in at least first longitudinal sections. The flat gasket is particularly useful for cases where machine part sealing surfaces between which the flat gasket is to be inserted do not have the component elasticity required for a reliable seal. The gasket sheet has at least one second sheet metal layer which has a height-elastic bead in the area of the base which, together with the base, forms a thickness-elastic area of the flat gasket. | 08-13-2009 |
20110179755 | Particle separating device for an aerosol stream - Separating device for separating liquid or solid particles from an aerosol stream, comprising an impactor with a perforated plate against which the stream flows, and an impact plate arranged at a short distance behind the perforated plate, the side of the impact plate against which the stream flows having a separating layer with an open structure; in order that the separating device will have a consistently good separating effect during operation, the perforated plate is provided on its rear side with a plurality of spacer elements bearing against the region of the separating layer against which the stream flows, the height of the spacer elements, the support surfaces formed by the spacer elements for the separating layer, and the number and arrangement of the spacer elements being selected in dependence upon the material of the separating layer such that it is ensured that the holes of the perforated plate remain free from material of the separating layer also during operation. | 07-28-2011 |
