Emerson Process Management’s Fisher FIELDVUE DVC6200 digital valve controller (DVC) family gains added capability with its all-stainless-steel housing that withstands the corrosive atmospheres often experienced in chemical plants, pulp and paper mills, as well as near-shore and offshore oil and gas installations.
All DVC6200 series instruments detect valve position using a patented linkage-less, non-contact feedback design. This valve-positioning technology eliminates any travel feedback issues caused by corrosion, high cycle or high vibration applications.
In addition to external protection, the stainless steel housing with the digital controller’s fully encapsulated printed wiring boards provides good corrosion resistance. A separate, weather-tight field wiring terminal box that isolates the field wiring connection from other areas of the instrument further enhances the internal component protection.
The DVC6200 series is offered with CSA, IECEx, ATEX and FM hazardous area approvals as well as other certifications and approvals. It is also listed in the Lloyd’s Register for industrial, marine and offshore use.
