Method for contactless determination of electrical potential using oscillating electrode, and device
Patent number: 9121878Abstract: The electrical potential of an object is determined by providing a mechanically oscillating electrode located at a distance from the object and making the electrode mechanically oscillate. A change in a state of electric charge of the electrode over time and amplitudes of at least two frequency components during the change in the state of electric charge over time are determined. Based on the amplitudes, at least one parameter that forms part of the value of a capacitance of an arrangement formed by the electrode and the object is determined, so that the capacitance of the arrangement formed by the electrode and object can be determined based on the parameter. Finally, the electrical potential is determined from the change in the state of electric charge and the capacitance.Type: GrantFiled: April 14, 2011Date of Patent: September 1, 2015Assignee: SIEMENS AKTIENGESELLSCHAFTInventors: Jens Makuth, Dirk Scheibner, Jürgen Schimmer -

Publication number: 20140145730Abstract: A device for the contactless determination of an electrical potential of an object, has an electrode and a potential controller which is electrically connected to the electrode. The potential controller changes a reference potential applied to the electrode to a final value in such a way that an electric field between the object and the electrode disappears at the final value if the electrode is located at a distance from the object.

Publication number: 20140123772Abstract: A force transducer, in particular a load cell, includes a spring body that deforms when loaded with a force or load to be measured. Two support parts, which are separated by a gap, are moved out of a position of rest. A capacitive displacement detector is used to detect the relative movement of the support parts, where the capacitor includes two electrode combs that are each held on one of the support parts and includes a multiplicity of electrode fingers. The electrode combs are configured designed and mounted on the two support parts such that the electrode fingers of the one electrode comb pass into the finger interspaces of the other electrode comb when the spring body is loaded so that the force transducer is resistant to overloading.Type: ApplicationFiled: May 11, 2012Publication date: May 8, 2014Inventors: Karlheinz Amtmann, Dominik Braun, Jörg Hassel, Harry Hedler, Hans-Peter Lindner, Delphine Meunier, Daniel Reznik, Klaus Röther, Dirk Scheibner, Arno Steckenborn, Oliver Theile

Publication number: 20140111189Abstract: A method for the contactless determination of an electrical potential of an object, involves providing an electrode which is spatially at a distance from the object, connecting the electrode to a reference potential, determining a first temporal change in an electrical state of charge of the electrode at a first value for the electric flux between the electrode and the object, determining a second temporal change in the electrical state of charge of the electrode at a second value for the electric flux between the electrode and the object, and determining the electrical potential of the object at least from the first temporal change in the electrical state of charge and the second temporal change in the electrical state of charge and from a difference between the first value and the second value for the electric flux.Type: ApplicationFiled: April 14, 2011Publication date: April 24, 2014Inventors: Jens Makuth, Dirk Scheibner, Jürgen Schimmer

Publication number: 20140102218Abstract: A force transducer, in particular a weighing cell, includes a spring body, which deforms under the action of a force or load to be measured, and a sensor that includes two separate sensor parts mounted at different locations of the spring body and that generates a sensor signal which is dependent on the relative position of the sensor parts with respect to each other. In order to improve the adaptation of the sensor to the spring body, one of the sensor parts is attached to the spring body with interposition of an electromechanical actuator and a control device is present, which controls the actuator dependent on the sensor signal in the direction of a reduction in the positional difference of the sensor parts.Type: ApplicationFiled: May 11, 2012Publication date: April 17, 2014Inventors: Dirk Scheibner, Arno Steckenborn

Patent number: 7878066Abstract: The invention relates to a vibration measurement system for frequency-selective oscillation measurement in particular of low frequencies as are relevant in the field of automation and drive technology. The invention proposes coupling a broadband transmitter structure, which is excited directly by the excitation signal to be determined, via an electrostatic or inductive force to a receiver structure. This force coupling results in amplitude modulation of a carrier signal exciting the receiver structure. The actual excitation signal can be extracted from the spectrum of the amplitude-modulated carrier signal, for example by suitably selecting the frequency of the carrier signal. In order to make an oscillation analysis possible which is as unsusceptible to interference possible, an interference signal brought about, for example, by connector excitations is largely eliminated in advance from the amplitude-modulated carrier signal.Type: GrantFiled: August 2, 2006Date of Patent: February 1, 2011Assignee: Siemens AktiengesellschaftInventors: Dirk Scheibner, Jens Makuth

Patent number: 7819012Abstract: A vibration measuring system for the frequency-selective measuring of especially low-frequency vibrations relevant in the area of automation and motive power engineering is disclosed which allows an economical vibration analysis of frequencies in the range of from 0 to 1 kHz. For this purpose, a broad-band transmitting structure which is directly induced by the excitation signal to be determined is coupled to a receiving structure by an electrostatic or inductive force. This force coupling brings about an amplitude modulation of a carrier signal inducing the receiving structure. The spectrum of the amplitude-modulated carrier signal can then be used to extract the actual excitation signal, e.g. by suitably choosing the frequency of the carrier signal.Type: GrantFiled: June 12, 2006Date of Patent: October 26, 2010Assignee: Siemens AktiengesellschaftInventors: Jan Mehner, Jens Makuth, Dirk Scheibner
