1. Product Introduction
The fisherr DVC2000 is a microprocessor-based digital valve controller designed by Emerson for precise valve positioning and advanced diagnostics in industrial process control systems. As part of the FIELDVUE™ instrument family, it integrates HART® 5 communication, non-contact position sensing, and ruggedized construction to optimize valve performance across industries like oil and gas, chemical processing, power generation, and water treatment .
Key Specifications:
Input Signal: 4-20 mA HART 5 (standard)
Actuator Compatibility: Single-acting (direct/reverse)
Operating Temperature: -40°C to +80°C (-40°F to +176°F)
Max Inlet Pressure: 7 barg (100 psig)
Hazardous Area Certifications: ATEX, IECEx, FM, NEPSI, and others
Construction Materials: Aluminum housing (standard), optional stainless steel components
Communication Protocols: HART 5 (base model), with optional ValveLink™ software integration .
2. Product Features

Non-Contact Feedback System: Utilizes magnetic Hall-Effect sensors and stem-mounted magnet arrays to eliminate mechanical linkages, reducing wear and maintenance .
Auto-Calibration: Automatically tunes to valve characteristics, ensuring optimal response times and minimizing setup effort .
High Resolution: Achieves positioning accuracy within ±0.5% of span, even in dynamic process conditions .
2.2 Diagnostic Capabilities
Multi-Level Diagnostics:
AC (Auto Calibration): Basic functionality with remote HART communicator access.
HC (HART Communication): Alerts and basic diagnostics via HART.
AD (Advanced Diagnostics): Offline diagnostics with ValveLink software.
PD (Performance Diagnostics): Real-time, in-service diagnostics for predictive maintenance .
Integrated Limit Switches: Two isolated switches (1 mA or 4 mA output) for open/closed position indication .
2.3 User Interface & Connectivity
Local User Interface (LUI):
Full-text LCD display with 4-button navigation.
Support for 12 languages (English, German, Chinese, Arabic, etc.), expandable via optional language packs .
HART Integration: Enables bidirectional communication for remote configuration, monitoring, and diagnostics .
ValveLink™ Software Compatibility: Facilitates advanced diagnostics, performance trending, and compliance reporting .
2.4 Ruggedized Design
Hazardous Environment Compliance: Certified for use in explosive atmospheres (ATEX, IECEx) with intrinsically safe (Ex ia) and flameproof (Ex d) options .
Modular Construction: Easy maintenance without disconnecting pneumatic or electrical connections .
Weatherproof Housing: IP66/IP67 ratings for dust and water resistance in outdoor installations .
