A diagnostic device and method for an intelligent pressure regulator which maintains a fluid in a process at a predetermined pressure. The regulator includes an electronic controller which enhances regulator performance and provides self-diagnostics and communications capabilities. The electronic controller includes a pressure sensor which provides a signal indicating the pressure of the fluid being controlled, an adjusting pressure for adjusting the position of a throttling element; and a PID controller which receives the signal indicating the pressure of the fluid being controlled and applies the adjusting pressure to the actuator in response to the signal.
L'invention concerne un dispositif et un procédé pour régulateur de pression intelligent maintenant un fluide à une pression préétablie dans le cadre d'un processus. Le régulateur comprend un contrôleur électronique qui améliore les performances de régulation et assure des fonctions d'autodiagnostic et de communication. Le contrôleur électronique comporte un capteur de pression qui fournit un signal indiquant la pression du fluide à contrôler, il donne une pression d'ajustement qui permet d'ajuster la position d'un élément de réglage du débit, et il comprend en outre une commande proportionnelle, intégrale et dérivée recevant le signal indicateur de la pression du fluide à contrôler et appliquant la pression d'ajustement à l'actionneur, en réponse au signal.
