Valve Controllers Profibus Compatible Valve Controllers for Remote Applications

| Editor: Dominik Stephan

Emerson Process Management has introduced the Fisher Fieldvue DVC6200p series of digital valve controllers. The DVC6200p is well–suited for applications in which accessibility, extreme temperatures (up to 120°C/250°F), extreme vibration or confined space make integral mounting difficult or impractical.

Industries such as pulp and paper, and metal and mining have typically preferred to isolate valve mounted instruments from harsh environments. With the remote mount version of DVC6200p, only the valve position feedback is mounted on the control valve, while the remainder of the digital valve controller can be mounted over 90 metres (300 feet) away in a less severe or more accessible environment.

The remote valve mounted feedback unit utilises the patented Fieldvue linkage-less, non-contact feedback technology, in which physical contact has been eliminated between the valve stem and the instrument. With no linkage to wear, loosen, corrode or vibrate, the feedback unit can withstand a plant’s operating extremes.

Valve Controllers for Certified for Profibus

With over 1.5 million units installed worldwide, Fieldvue digital valve controllers prove highly suited to difficult process environments where they provide unmatched valve operation. Utilising Profibus PA, the DVC6200p series provides a wealth of alerts, trends, and diagnostics to allow for visibility and control. The DVC6200p supports enhanced device description (EDD) files that allow for quick and easy configuration. Quick setup and calibration, including performance tuning, can be performed locally in a matter of minutes. For more extensive parameterisation, leading Profibus configuration tools can be used. The Fieldvue DVC6200p digital valve controller is certified to Profile 3.02 for Profibus PA devices by the Profibus Nutzerorganisation (PNO). The DVC6200p is offered with CSA, IECEx, ATEX and FM hazardous area approvals as well as other certifications/approvals. It is also listed in the Lloyd’s Register for industrial, marine and offshore use.
