Abstract: An electronic device having a housing for accommodating electronic components, preferably electronic components forming a process transmitter. The housing has two chambers, in which electronic components and user interfaces and/or connection elements for cable are arranged. The electronic components are arranged in a first chamber. In the case of a process transmitter, which is simple to maintain, electronic components are arranged exclusively in the first chamber, while user interfaces of the electronic components and/or connection elements for cable are positioned exclusively in the second chamber.

Abstract: 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.

Abstract: 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.

Abstract: An electronics housing comprises a housing basic body having a cavity, especially a single cavity. The housing basic body includes a side wall laterally bordering the cavity, an open end and a rear wall bounding the cavity on an end lying opposite the open end and remote therefrom. Also included is a housing lid releasably connected to the housing basic body on the open end and sealing the housing basic body; and an intermediate floor. The intermediate floor, in the case of the electronics housing of the invention, forms: a gap extending between an inner surface of the side wall of the housing basic body and a lateral surface of the intermediate floor facing the inner surface; and two housing chambers in the cavity of the housing basic body separated from one another by the intermediate floor. A first housing chamber is arranged on a first side of the intermediate floor facing the housing lid and a second housing chamber is arranged on a second side of the intermediate floor facing away from the housing lid.
