Emerson Process Management has expanded its intelligent field device offering with introduction of the FOUNDATION™ Fieldbus-based Fisher FIELDVUE DVC6000f digital valve controller.  Carrying forward the industry benchmark performance of FIELDVUE valve controllers, the DVC6000f features the fast, accurate response, and built-in valve diagnostics that help process manufactures improve control and availability while reducing maintenance costs. 

Improved availability and reduced maintenance costs result directly from the performance diagnostic (PD) capability built into the DVC6000f instrument.  PD inside runs continuously, analyzing valve and actuator data while the valve remains in service, controlling the process.  Using the PD information the DVC6000f can trigger PlantWeb alerts that forewarn of valve performance problems, enabling corrective action before a degraded valve can impact process operation.

Further to maintenance benefits, valve and actuator specification data for diagnostic use is embedded in the DVC6000f instrument during factory mounting of the digital valve controller to the valve, ensuring that you have the data when it's needed.

Hot cutover to Fieldbus protocol is possible without taking the process down because the DVC6000f instrument can function in two operating modes, pressure and travel.  Further flexibility exists also as firmware upgrades to add functionality to the DVC6000f instrument are easily downloaded over the Fieldbus segment wiring, without interruption to process operations.  Reduced process variability through tighter closed loop control increases the bottom line for quality and profitability.  This owes in part to the fast AO and PID block execution of the DVC6000f that supports an extremely fast (100 millisecond) loop macro-cycle.  Harsh environments such as temperature extremes, corrosive atmospheres and hazardous areas are not a problem for the robust controller that offers optional stainless steel construction and remote mounting to provide added durability.
