Patent ID: 7792646

Claim:
A measuring arrangement for registering chemical and/or physical, measured variables, comprising: at least one measuring device, which, by means of internal measuring device electronics, repeatedly generates, during operation, measured values representing at least one measured variable to be registered; and an electronics data processing system superordinated to said at least one measuring device; wherein: said measuring device and said electronics data processing system are connected to one another by means of at least a first line-pair, through which a first electrical current flows, at least at times, during operation, and by means of at least a second line-pair, through which a second electrical current flows, at least at times, during operation; said measuring device transmits internally generated, measured values to said electronics data processing system at least partially via said first line-pair and at least partially via said second line-pair; and for transmitting internally generated, measured values to said electronics data processing system, the measuring device: sets an electrical current level of the current flowing, at least at times, through said first line-pair, and/or sets an electrical current level of an electrical current flowing, at least at times, through said second line-pair.
