DIAGNOSE-VORRICHTUNG UND -METHODE FÜR DRUCKREGLER |
摘要 |
<p>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.</p> |
