Measuring Arrangement for Registering Chemical and/or Physical, Measured Variables, as well as Measuring Device therefor
First Claim
1. The measuring device, comprising:
- a measuring transducer reacting to changes of at least one physical or chemical, measured variable and delivering at least one measurement signal influenced by the at least one measured variable; and
a measuring device electronics connected to said measuring transducer, wherein;
said measuring device electronics is connectable to a superordinated, electronics data processing system by means of at least a first line-pair and by means of at least a second line-pair; and
said measuring device electronics is designed for, during operation, generating a plurality of measured values representing, at least in part, the at least one measured variable and for transmitting these measured values to the connected data processing system at least partially via said first line-pair and at least partially via said second line-pair.

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.
