METHODS AND APPARATUS TO USE VIBRATION DATA TO DETERMINE A CONDITION OF A PROCESS CONTROL DEVICE

摘要

Methods and apparatus to use vibration data to determine a condition of a process control device are disclosed. An example method includes collecting first vibration data from a first sensor operatively coupled to a process control device during a calibration. The example method further includes calculating an operating threshold of the process control device based on the first vibration data, and determining a condition of the process control device if second vibration data associated with the process control device collected after the calibration exceeds the operating threshold.
