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.

Abstract: Methods and apparatus for controlling multiple valves as a single valve based on a coordinated control signal are disclosed. In some examples, an apparatus includes a valve controller to be operatively coupled to a first valve and a second valve. In some examples, the second valve is to be operatively positioned in series with the first valve. In some examples, the valve controller is to control a position of the first valve and a position of the second valve based on a coordinated control signal to be received by the valve controller.

Abstract: 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.
