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.
Claims23
A method comprising:
- collecting first vibration data from a first sensor operatively coupled to a process control device during a calibration;
- 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.
A method comprising:
- collecting first vibration data from a first sensor operatively coupled to a process control device and second vibration data from a second sensor operatively coupled to a pipe, wherein the pipe is coupled to the process control device;
- calculating a ratio based on the first vibration data and the second vibration data;
- and
- indicating a condition of the process control device if the ratio is greater than a threshold value.
A method comprising:
- collecting vibration data from a first sensor operatively coupled to a process control device;
- receiving diagnostic vibration data associated with the process control device;
- comparing the vibration data to the diagnostic vibration data;
- and
- indicating a condition of the process control device based on the comparison.
A method comprising:
- collecting first vibration data from a first sensor operatively coupled to a process control device;
- identifying a characteristic of the process control device from the first vibration data;
- determining if the characteristic is within a known range;
- and
- when the characteristic is within the known range, indicating a condition of the process control device.
