Patent number: 11237066Abstract: A temperature-determining device for determining a temperature (TMED) of a medium via a temperature of a surface includes: an ambient-temperature sensor, arranged in surroundings of the surface, for measuring an ambient temperature (TU); a surface-temperature sensor, lying on the surface, for measuring a mixed temperature (TM) lying between the temperature (TMED) of a medium and the ambient temperature (TU); and an arithmetic-logic unit having an approximation formula electronically stored thereon for calculating an approximation (TMEDN) of a temperature of a medium. The approximation formula is a sum of the mixed temperature (TM) and a product of two factors. The first factor results from a difference between the mixed temperature (TM) and the ambient temperature (TU) and the second factor results from a ratio of a dividend to a quotient. The dividend results from a difference between a calibration temperature (TMEDKAL) of a medium and a calibration mixed temperature (TMKAL).Type: GrantFiled: October 11, 2018Date of Patent: February 1, 2022Assignee: ABB SCHWEIZ AGInventor: Tilo Merlin

Patent number: 10718642Abstract: A method for checking an operability of two-wire measuring transducers in automation technology which output a measurement signal as an impressed loop direct current via a two-wire line and active assemblies of which are supplied with electrical energy via the two-wire line includes: measuring the loop direct current and an input voltage of the measuring transducer; increasing the loop direct current in a range from a minimum value to a maximum value independently of the measured value, while measuring the input voltage of the measuring transducer; storing the measured values of the input voltage at selected measuring points of the loop direct current as an individual signature of the measuring transducer; and, during ongoing operation, measuring the input voltage at connection terminals of the two-wire line via an internal resistance of the measuring transducer at a prevailing loop direct current and recursively comparing that with the signature.Type: GrantFiled: February 28, 2019Date of Patent: July 21, 2020Assignee: ABB SCHWEIZ AGInventors: Horst Schwanzer, Tilo Merlin

Publication number: 20160223411Abstract: A thermometer has at least one temperature sensor, having a physical variable which changes in a characteristic manner depending on temperature, at least one electrical output for emitting a signal which is a measure for the value of the variable, a transmitter for a sound wave or an electromagnetic wave, which transmitter can be coupled to the temperature sensor and controlled thereby depending on the variable's value, or can radiate the wave at least in part towards the temperature sensor, the wave-temperature sensor interaction depending on the variable's value, and either a wave receiver, which reconverts the wave into an electrical signal, or another unit for converting the wave-temperature sensor interaction into an electrical signal, connected to the electrical output.Type: ApplicationFiled: February 2, 2016Publication date: August 4, 2016Inventors: Joerg Gebhardt, Ulf Ahrend, Kai Koenig, Andreas Decker, Stephan Wildermuth, Paul Szasz, Tilo Merlin, Horst Schwanzer

Patent number: 8342741Abstract: A method is disclosed for operating a sensor arrangement having at least one measuring sensor and at least one reference sensor for recording the same physical variable, and having an analysis unit electrically connected thereto, with a characteristic of the sensor arrangement being recorded in an initialization phase from measured values of the at least one measuring sensor and of the at least one reference sensor, and an alarm being given during continuous operation if the deviation from the characteristic lies outside a tolerance band. It is proposed to suspend the alarm dynamically so long as the changes in the measured value in the variation over time of the at least one measuring sensor or in the variation over time of the at least one reference sensor differ by more than a definable limit within a definable time interval.Type: GrantFiled: August 28, 2007Date of Patent: January 1, 2013Assignee: ABB AGInventors: Harald U.

Patent number: 7953570Abstract: A method is disclosed for continuous analysis of the transmission quality in fieldbus networks in automation systems with a plurality of fieldbus participants, which communicate with one another over the fieldbus network. Directly measurable logical and physical bus parameters are recorded from the line signal transmitted over the fieldbus network, and are stored with a predefinable retrospectivity. Operational parameters are derived from the measured bus parameters, these being weighted and the weighted bus parameters being linked together to form the operational parameter. The quantitative weighting of a bus parameter is functionally determined by at least one other bus parameter.Type: GrantFiled: September 11, 2007Date of Patent: May 31, 2011Assignee: ABB AGInventors: Tilo Merlin, Peter Ude

Publication number: 20090187691Abstract: The disclosure relates to a method for operating a bus system, in which a plurality of subscribers communicate with one another over the same bus line and all subscribers are assigned a subscriber address from a limited address set. To avoid address conflicts, it is suggested that by each subscriber newly added to an existing bus system, the bus traffic will be monitored before the first send access to the bus with the current subscriber address, in order to form a list of already used subscriber addresses. The subscriber then assigns itself an address from the as yet unused address space according to a predefinable schema.Type: ApplicationFiled: October 24, 2007Publication date: July 23, 2009Applicant: ABB AGInventors: Ralf Huck, Tilo Merlin

Patent number: 7558691Abstract: A method is disclosed for determining a characteristic of a sensor arrangement having at least one measuring sensor and at least one reference sensor for recording the same physical variable, and having an analysis unit electrically connected thereto. The characteristic is determined from measured values of the at least one measuring sensor and of the at least one reference sensor. It is proposed to record a characteristic point during continuous measurement operation, starting with the first time the sensor arrangement is put into operation, when a definable measurement point is reached in a process for the first time, if the changes in measured value in the variation over time of the at least one measuring sensor and in the variation over time of the at least one reference sensor remain within a definable tolerance band within a definable time interval.Type: GrantFiled: August 28, 2007Date of Patent: July 7, 2009Assignee: ABB AGInventors: Harald U.

To avoid address conflicts, it is suggested that by each subscriber newly added to an existing bus system, the bus traffic will be monitored recursively before the first send access to the bus with the current subscriber address, and if its own subscriber address is detected in the bus traffic the subscriber's own address is changed by a predefinable offset.Type: ApplicationFiled: October 23, 2007Publication date: May 1, 2008Applicant: ABB Patent GmbHInventors: Ralf Huck, Tilo Merlin, Stefan Svensson
