TIME-STAMPED EMISSIONS DATA COLLECTION FOR PROCESS CONTROL DEVICES.

摘要

The claimed method and system provide a process control device monitoring system and a process control valve assembly with a process control device monitoring system to measure one or more operating states of a process control device. The process control device monitoring system may also associate a time- stamp with the one or more measured operating states of the process control device in response to a trigger generated based on the one or more measured operating states. The process control device monitoring system may also transmit the time- stamp and an indication of the one or more operating states to a monitoring device.
