Digital Positioners

Digital valve controllers use microprocessors and have become the dominant replacement technology for conventional and electro-pneumatic positioners since the mid 1990s. Fisher® FIELDVUE™ digital valve controllers integrate functionality far beyond the traditional analog or pneumatic positioner. The benefits of using a  FIELDVUE digital valve controller include: Availability of equipment alerts to notify the user of pending issues, automated configuration, calibration and tuning , and access to advanced levels of valve assembly diagnostics. This provides consistent and predictable knowledge of valve assembly performance and condition regardless who performs the task.
