METHOD AND SYSTEM FOR ADJUSTMENT OF MOVEMENT SENSOR ALIGNMENT ON PROCESS CONTROL VALVES Russian patent published in 2019 - IPC F16K37/00 

FIELD: physics.

SUBSTANCE: present invention generally relates to calibration of sensor and, in particular, to methods and systems for controlling alignment of displacement sensor used in process control valves. To simplify the process of adjusting the displacement sensor on the process control valves, the method and system generate a graphical interface for displaying alignment information to the user or operator. Graphical interface visualises the alignment state between the feedback element and the sensitive element, which includes a magnetic displacement sensor on the process control valve. Using the graphical interface, the user or operator can easily determine whether alignment between the feedback element and the sensing element is proper or correct. In addition, the graphical interface provides information on whether physical adjustments are required to correct detected alignment problems, thereby avoiding near failures, thereby achieving optimum characteristics.

EFFECT: method and system improve reliability and accuracy of valve movement feedback.
