Fisher™ FIELDVUE™ DVC2000 Digital Valve Controller

 

The performance and simplicity of the Fisher FIELDVUE DVC2000 instrument allows for your operation to run closer to setpoint, improving product quality with more accurate control. Using FIELDVUE Performance Diagnostics, valve operation is monitored online to evaluate performance and reliability.

 

 

Features

 

• The linkage-less feedback system is easy to install. At its very basic functionality, the DVC2000 digital valve controller has a local user interface that will allow you to configure, calibrate, and tune the instrument
• Years of control experience has brought this product line to a high level of reliability and dependability.
• The two-stage positioner design provides a mechanical platform that enables responsiveness to small input changes and tighter process control.
• Tests can be performed to identify problems with the entire control valve assembly using ValveLink™ software, which assists in pinpointing problems without disrupting the process and before the equipment fails.
• Available with an I/O Options Package which includes two integral limit switches and a stem position transmitter.
• Features a compact size with multilingual liquid crystal display.
• Integral mounting is available on Fisher GX, and 657 and 667 size i actuators.

DVC2000 Digital Valve Controller

DVC2000 Digital Valve Controller | Fisher Fieldvue

DVC2000 Digital Valve Controller is simple to use, compact, and designed for easy mounting. It converts a 4-20 mA input signal into a pneumatic output signal, which feeds the control valve actuator. Instrument setup is performed with an
enclosed push button and liquid crystal display (LCD) interface. The interface supports multiple languages, available in two language pack options.

FIELDVUET DVC2000 digital valve controllers are HART® communicating, microprocessor-based current-to-pneumatic instruments. Using technologies and experience learned from the DVC6000 product line, new features and capabilities have been added to address additional application needs including: These features and capabilities were developed to support a global customer base that requires a simple, easy to use, digital valve controller. Most striking is the patented non-contact, linkage-less valve position feedback system. With no touching parts, the feedback system capitalizes on magnetic technology while improving instrument reliability on linear or rotary valves. Configuration of the DVC2000 is simple with the full text, multilingual local user interface. English, German, Italian, Spanish, French, Chinese and Japanese languages are supported in every device.
