Fisher Enhances FIELDVUE® Digital Valve Controller Line

MARSHALLTOWN, IOWA, July 2001 . . . . . Fisher Controls International LLC, an Emerson Process Management company, has enhanced its FIELDVUE Digital Valve Controller line by extending the controllers’ use to double-acting valve actuators without requiring auxiliary signal-switching equipment. Designated the DVC6000 Series, the enhanced FIELDVUE controllers are compatible with most brands of pneumatic valve actuators. The DVC6000 controllers reduce the cost of control valve purchase, installation, operation and maintenance.

Microprocessor-based, the enhanced FIELDVUE instruments offer two-way digital communications utilizing the HART® protocol. By using a HART Communicator, a notebook PC or a workstation, employees can operate the FIELDVUE controller from a remote location, which minimizes their exposure to hazardous situations and avoids tough-to-reach valve locations. Maintenance personnel can quickly commission loops by identifying each instrument, verifying or changing its calibration, reviewing previously stored maintenance notes, and more. When utilized within a HART multiplexer system, the DVC6000 Series controllers can notify about existing and potential valve and instrument problems.

The valve-mounted FIELDVUE instruments provide real-time data on such critical valve parameters as input signal, stem position, and actuator pressure. System operators can utilize this information to improve loop control, enhance process safety, and ensure compliance with environmental requirements.

The FIELDVUE controllers also allow analysis of such valve dynamics as step response and dynamic error band, which enables instrument and process engineers to optimize loop performance as well as identify unwanted performance changes that might jeopardize product quality.

Other benefits provided by the enhanced FIELDVUE Digital Valve Controllers include faster commissioning; improved process quality; reduced process downtime; and reduced maintenance.

Leak detectors or limit switches can be connected to auxiliary terminals within the instruments without requiring additional field wiring. This allows the FIELDVUE controller to issue an alert should limits be exceeded. FIELDVUE instruments also provide easy tracking and alerting of valve stem packing wear, which can be used in making valve maintenance schedules.

The new controllers incorporate such design features as fully encapsulated wiring boards for resistance to vibration and corrosive atmospheres, a separate field wiring termination compartment that isolates field wiring connections, and a NEMA 4X, IEC 60529 IP65 housing. The DVC6000 Series has been awarded FM, CSA, and LCIE approvals.
