Patent number: 8674241Abstract: A weighing device having a plurality of digital weighing cells (164), each including a sensor connected to a force transmission unit (163), each generating a digital measurement value corresponding to a transmitted force at a measurement time point, and including a data processing device that converts the digital measurement values to transmission units configured to be transmitted over a data communications line (20) to a central control unit (18) connected to all weighing cells for analysis of the transmission units. The central control unit (18) calculates a digital combination value based on the transmission units originating from the various weighing cells (164), the combination value representing a weight force with which the weighing device (16) is loaded at a weighing time point. The conversion of the measurement values to transmission units involves a pairing of each converted measurement value with a time value.Type: GrantFiled: June 7, 2010Date of Patent: March 18, 2014Assignee: Sartorius Weighing Technology GmbHInventors: Alfred Klauer, Christian Oldendorf, Thomas Schink, Erich Bettwieser

Patent number: 7906737Abstract: An electronic scale having a measuring sensor (1 . . . 16), a digital signal processing unit (18), a digital display (19) and an inclinometer (40). The inclinometer derives a signal for the tilt of the scale from the difference of at least two signals. The digital signal processing unit (18) is provided with an additional circuit component or program routine that adds the two signals and, by way of this cumulative signal, corrects the vibration-distorted signal of the measuring sensor (1 . . . 16). A plurality of inclinometers enables the simultaneous detection of momentary gravitational acceleration. For example, in an electric bubble level, the gas bubble moves out of place when tilted and the diameter of the gas bubble changes when the gravitational acceleration changes. The scale thus provides an additional signal for correcting the influence of disturbances with minimum complexity.Type: GrantFiled: June 12, 2009Date of Patent: March 15, 2011Assignee: Sartorius AGInventors: Gerd Freydank, Winfried Graf, Christian Oldendorf
