Abstract
To simplify the process of adjusting travel sensor alignments on process control valves, a method and system generates a graphical interface to display alignment information to a user or operator. The graphical interface visualizes the state of alignment between a feedback element and a sensing element that comprise a magnetic travel sensor on a process control valve. Using the graphical interface, the user or operator can easily determine whether the alignment between the feedback element and the sensing element is proper or correct. The graphical interface also provides information on whether or not physical adjustments are needed in order to fix detected alignment problems so that impending failures can be avoided and optimal performances can be achieved. In this manner, the method and system improves the reliability and accuracy of valve travel feedback.
