Patent number: 8099249Abstract: 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.Type: GrantFiled: September 22, 2009Date of Patent: January 17, 2012Assignee: Vega Grieshaber KGInventors: Joern Jacob, Holger Gruhler

Publication number: 20100175476Abstract: 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; and, the field coil and the permanent magnet are arranged to interact in such a way that any vibration of the permanent magnet induces current flow in the field coil and/or induces vibration of the permanent magnet in the field coil.Type: ApplicationFiled: December 1, 2009Publication date: July 15, 2010Inventors: Joern Jacob, Holger Gruhler, Josef Fehrenbach, Martin Mellert, Frank Becherer
