摘要:
A smart valve positioner is provided with a local user interface with non-mechanical touch buttons and a display inside a positioner housing under a housing cover for locally operating the valve positioner. The touch buttons are user-operable by touching the touch buttons when the housing cover is open. The housing cover is arranged to make the touch buttons user-operable from outside the housing by touching the housing cover, when the housing cover is closed.
