ABSTRACT:
The claimed method and system identifies faults and/or deterioration of components in a process control valve. The system may use different sensor combinations to provide the necessary data to compute irregular component integrity. Alerts may be generated to indicate potential component integrity problems. In particular, the system may detect potential deterioration and/or faults in actuator springs, pneumatic tubing and piping, and bellows seals. The claimed system may be communicatively coupled to a process control network to provide a more elaborate alarm system. Moreover, additional statistical methods may be used to refine the detection accuracy of the system.
