Abstract

''REGULADOR DE PRESSãO, DISPOSITIVO PARA SENTIR CAVITAçãO E INTERMITêNCIA EM UM REGULADOR DE PRESSãO, E, PROCESSOS DE REALIZAçãO DE DIAGNóSTICOS EM LINHA EM UM REGULADOR DE PRESSãO, DE DETERMINAçãO DE SENSIBILIDADE DA PRESSãO DE ENTRADA DE UM REGULADOR DE PRESSãO, E DE DETERMINAçãO DO ERRO HISTERéTICO DE UM REGULADOR DE PRESSãO''. Um dispositivo de diagnóstico e processo para um regulador de pressão inteligente que mantém um fluido em um processo a uma pressão predeterminada. O regulador inclui um controlador eletrónico que melhora o desempenho do regulador e fornece auto diagnósticos e capacidades de comunicações. O controlador eletrónico inclui um sensor de pressão que fornece um sinal indicando a pressão do fluido sendo controlado, e o ajuste de pressão para ajustar a posição de um elemento de estrangulamento; e um controlador PID que recebe o sinal indicando a pressão do fluido sendo controlado e aplica a pressão de ajuste ao atuador em resposta ao sinal.
