The Bently Nevada 3300/65 Dual Valve Position Indicator is a specialized monitoring module engineered for the 3300 Series rack system. This unit provides dual-channel monitoring capabilities, specifically designed to track valve stem travel and position in critical rotating machinery such as steam and gas turbines. By integrating directly into the 3300 rack, it offers reliable position feedback and protection logic for industrial valve control applications.
Features
Dual independent channels for redundant or multi-valve position monitoring.
Continuous signal processing with integrated Alert and Danger alarm setpoints.
Proportional analog outputs (4 to 20 mA and 1 to 5 VDC) for external integration with control systems.
Integrated LED status indicators for real-time monitoring of OK, Bypass, Alert, and Danger states.
Designed for seamless integration into existing Bently Nevada 3300 monitoring racks.
Applications
This module is primarily utilized in power generation and petrochemical facilities to monitor critical valve positions. It is essential for detecting valve travel issues, ensuring machinery safety, and providing high-fidelity position data to plant DCS or PLC systems.
