Abstract

"INSTRUMENTO DE BARRAMENTO DE DUAS LINHAS". Um instrumento de barramento de duas linhas (500) adaptado para uso com um barramento de duas linhas (308) é fornecido de acordo com uma modalidade da invenção. Um elemento do instrumento (304) recebe uma terceira corrente e gera um ou mais sinais de medição do sensor. Um processador de sinal (512) recebe uma segunda corrente e processa o um ou mais sinais de medição do sensor para produzir um sinal de dados. Um sistema de comunicação (511) recebe uma primeira corrente, recebe o sinal de dados, gera um sinal digital de comunicação incluindo o sinal de dados, e modula o sinal digital de comunicação em um barramento de duas linhas (308) . Um suprimento de energia de comunicação (501) conectado através do barramento de duas linhas (308) fornece a primeira corrente ao sistema de comunicação (511). Um suprimento de energia de processamento de sinal (502) conectado através do barramento de duas linhas (308) fornece a segunda corrente ao processador de sinal (512) . Um suprimento de energia da corrente de excitação (503) conectado através do barramento de duas linhas (308) fornece a terceira corrente ao elemento do instrumento (304).
