Abstract: 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).

Abstract: 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.

Abstract: A method for providing a controlling frontend for an operating device configured for operating a field device includes providing an operational frame, wherein the operational frame serves as a generic user interface and is based on a companion specification; reading a field device specification from a database, wherein the field device specification comprises a structured set of field device attributes, which are related to the operating elements; and generating, based on the field device specification and the operational frame, a structured set of display elements for the controlling frontend, wherein at least some of the display elements of the controlling frontend are connected to the operating elements of the field device.
