Embodiment Construction

[0014] Specific examples are shown in the aforementioned figures and described in detail below. In describing these examples, like or identical reference numerals are used to identify identical or similar elements. The figures are not necessarily drawn to scale, and some figures and certain views of the figures may be shown exaggerated in scale or schematically. Additionally, a number of examples have been described throughout this specification. Any feature from any example may be included with, replaced with, or combined with other features from other examples.

[0015] Although the following methods and apparatus are described in conjunction with a control valve assembly, the exemplary methods and apparatus may also be used with any other process control equipment. Processes, such as industrial processes, are typically controlled by a wide variety of process control devices. These process control devices may include actuators and linear valves. Structural damage or wear...

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.

Description

technical field [0001] The present disclosure relates generally to process control equipment, and more particularly to methods and apparatus for using vibration data to determine the condition of process control equipment. Background technique [0002] Process control systems typically use a wide variety of process control devices to control processes. Vibration of components in these process control devices is inherent during operation. Components included in these process control devices are subjected to stresses over time that cause changes in vibration modes associated with the components. These stresses can reduce the performance of the process control equipment and degrade components and thereby reduce the remaining useful life of the process control equipment. Because these stresses can affect process control equipment to varying degrees, the service life of process control equipment also varies. Contents of the invention [0003] An exemplary method includes col...
