摘要： A driver circuit comprises: a voltage controller (UCD), which delivers a direct voltage (UPD) to a controller output; a direct voltage converter (DC/DC), to which is applied on the primary side the direct voltage (UPD) delivered from the voltage controller, and which converts such into a direct voltage (U′PD) available on the secondary side; and an end stage operated by means of said direct voltage (U′PD), which converts a control signal (sinexc—A) lying on a signal input into a driver signal (iexc) for the measuring transducer. The direct voltage (U′PD) available on the secondary side of the direct voltage converter (DC/DC) has, in such case, a magnitude which is always smaller than a magnitude of the direct voltage (UPD) delivered by the voltage controller, and the driver signal (iexc) has an electrical power (Pexc), which is higher than an electrical power (Psin) of the control signal (sinexc—A).

摘要： A measuring device electronics comprises a processor and two clock signal generators. One clock signal generator serves for producing a working clock signal, and also for producing a reference clock signal which is dependant on the working clock signal. The other clock signal generator, serves for producing a second reference clock signal, which is independent of the working clock signal. Based on the two independent reference clock signals, a frequency difference, can, to the extent that such is present, be ascertained during operation of the measuring device electronics or of the measuring device formed therewith. The frequency difference, represents a difference between the instantaneous clocking frequency of the first reference clock signal and the instantaneous clocking frequency of the second reference clock signal, and, in this respect, represents a measure for a deviation of an instantaneous clocking frequency, from the nominally predetermined clocking frequency, of the working clock signal.

摘要： A measuring arrangement of the invention includes: At least one measuring device, which generates, repeatedly during operation, measured values, especially digital, measured values, representing the at least one measured variable to be registered; as well as an electronic data processing system superordinated to the at least one measuring device, especially a data processing system which is spatially distributed and/or spatially remote from the measuring device. Measuring device and data processing system are connected together by means of at least two line-pairs, through each of which an electrical current flows, at least at times, during operation. According to the invention, the measuring device transmits the internally generated, measured values to the data processing system via both line-pairs. In this way, it is then possible to transmit a plurality of measured values simultaneously, when each of the two line-pairs is embodied as part of a two-conductor current-loop.

摘要： Field-device electronics including an electric current adjuster, through which a supply current flows. The electric current adjuster adjusts and/or modulates the supply current. The supply current is driven by a supply voltage provided by the external energy supply. Additionally, the field-device electronics has an internal operating and evaluating circuit for controlling the field device, as well as an internal supply circuit lying at a field-device electronics, internal input voltage derived from the supply voltage and feeding the internal operating and evaluating circuit. Provided in the supply circuit is a useful-voltage controller flowed-through, at least at times, by a first component of the supply current. The useful-voltage controller provides in the field-device electronics a first internal, useful voltage controlled to be essentially constant at a predetermined, first voltage level. Moreover, the supply circuit has a second useful-voltage controller flowed through, at least at times, by a second current component of the supply current. The second voltage controller provides in the field-device electronics a second internal, useful voltage, which is variable over a predetermined voltage range. Also contained in the supply circuit is a voltage adjuster flowed-through, at least at times, by a third current component of the supply current. The voltage adjuster serves to set and maintain the internal input voltage of the field-device electronics at a predetermined voltage level. In accordance with the invention, the operating and evaluating circuit is flowed-through, at least at times, both by a first useful current driven by the first useful voltage, and by a second useful current driven by the second useful voltage.

摘要： In an assembly for signal transfer between a receiving station and a transmitting station and for power supply of the transmitting station where these two stations are connected via a two-wire line, an analog signal current variable between two limiting values is transmitted via this two-wire line, this signal current representing a measured value sensed by a sensor. This current also forms the supply current needed to operate the transmitting station. In the transmitting station a circuit is provided, generating a constant operating voltage for the transmitting station. The transmitting station includes a controllable current source which dictates the current flowing via the two-wire line as a function of the measured value. A charge pump is connected to the output of the current source, the charge pump generating from the voltage appearing at the output of the current source all the operating voltage needed for operating the sensor and a signal processing circuit connected thereto.
