Digital Accuracy with New DVC2000, Predictive Diagnostics
The new DVC2000 series digital valve controller is the result of extensive consultation with customers. Designed in accordance with NAMUR standards IEC60534-6-1 and IEC60534-6-2, the DVC2000 can be mounted on Fisher and other brand actuators, enabling the industry-leading FIELDVUE performance to be applied to a wide range of applications across all industries.
Greater Accuracy
The superior performance is made possible by a two-stage, pre-amplifier design that multiplies small changes in the pneumatic signal. A digital tuning algorithm is also used to configure the DVC2000 to suit different actuators. Reliability on both linear and rotary valves is achieved by a contact-less magnetic position feedback system.
Simple Mounting, Usage and Controller Selection
The DVC2000 features a linkage-less design, making it easier to mount and remove the instrument from the valve. The push-button, LCD user interface supports English, Chinese, Japanese, German, Italian, Spanish, and French. This multi-language local interface is available during the quick setup routine, making calibration and tuning an easy task.
The DVC2000 offers an option for an integrated position transmitter and limit switches - versus external mounted options. This helps to simplify valve controller selection by reducing the need for additional engineering and specification.
Self-Diagnosis, Predictive Maintenance
The adage "Prevention is better than cure" applies to plant performance too. The DVC2000 helps identify problems early and avoid unplanned shutdowns, thanks to its unique Performance Diagnostics (PD) capability. Predictive diagnostics is a core feature of Emerson’s PlantWeb digital plant architecture.
Whilst the control valve is operating, critical valve performance information is available to evaluate and make decisions regarding the health of the entire control valve assembly. Information is communicated via the AMS ValveLink software or directly to the process automation system.
