A two-wire bus instrument (500) adapted for use with a two-wire bus (308) is provided according to an embodiment of the invention. An instrument element (304) receives a third current and generates one or more sensor measurement signals. A signal processor (512) receives a second current and processes the one or more sensor measurement signals to produce a data signal. A communication system (511) receives a first current, receives the data signal, generates a digital communication signal including the data signal, and modulates the digital communication signal onto a two-wire bus (308). A communication power supply (501) connected across the two-wire bus (308) provides the first current to the communication system (511). A signal processing power supply (502) connected across the two-wire bus (308) provides the second current to the signal processor (512). A drive current power supply (503) connected across the two-wire bus (308) provides the third current to the instrument element (304).

Selon une variante, l'invention concerne un instrument de bus bifilaire (500) pour bus bifilaire (308). Un élément d'instrument (304) reçoit un troisième courant et produit un ou plusieurs signaux de mesure de capteur. Un processeur de signaux (512) reçoit un deuxième courant et traite le ou le signaux de mesure pour produire un signal de données. Un système de communication (511) reçoit un premier courant, reçoit le signal de données, produit un signal de communication numérique comprenant le signal de données, et module le signal de communication numérique sur un bus bifilaire (308). Un système d'alimentation de communication (501) relié aux bornes du bus bifilaire (308) fournit le premier courant au système de communication (511). Un système d'alimentation de traitement de signal (502) relié aux bornes du bus bifilaire (308) fournit le deuxième courant au processeur de signal (512). Un système d'alimentation de courant d'entraînement (503) relié aux bornes du bus bifilaire (308) fournit le troisième courant à l'élément d'instrument (304).
