Abstract
Methods and apparatus to use vibration data to determine a condition of a process control device are disclosed. An example apparatus includes a vibration monitoring circuit to: collect first vibration data associated with a process control device during calibration of the process control device; calculate an operating threshold of the process control device based on the first vibration data; collect usage information associated with the process control device, the usage information indicative of a remaining portion of useful life associated with the process control device; adjust the operating threshold based on the usage information, the adjusted operating threshold reflective of the remaining portion of useful life associated with the process control device; and determine a condition of the process control device if second vibration data associated with the process control device collected after the calibration exceeds the adjusted operating threshold.
