Description

The Bently Nevada 3300/65 Dual Valve Position Indicator is a specialized monitoring module engineered for the 3300 Series rack system. This unit provides two independent channels dedicated to tracking valve position in critical rotating machinery, such as steam or gas turbines. By utilizing proximity probe inputs, the module delivers precise feedback on valve movement, facilitating both continuous operational monitoring and machine protection through integrated alarm and trip logic.

Features

• Dual-channel architecture for independent valve position measurement.
• Proportional output signals including +4 to +20 mA and +1 to +5 VDC for external integration.
• Integrated relay outputs configured for Alert and Danger alarm conditions.
• Front-panel status LEDs providing clear visual indication of OK, Bypass, Alert, and Danger states.
• Designed for seamless integration into existing 3300 Series rack architectures.

Technical Specifications

Installation Guidelines

• Ensure the 3300 rack is powered down before inserting or removing the module to prevent electrical damage or bus errors.
• Verify that the rack slot is clean and free of debris to ensure proper engagement of the backplane connectors.
• Use appropriate shielded cabling for transducer inputs to minimize electromagnetic interference (EMI) in high-noise industrial environments.
• Ensure the module is securely latched into the rack to maintain proper grounding and vibration resistance.
• Observe standard ESD handling procedures when touching the module circuitry.

FAQ

What is the function of the XX in the model code?

The XX suffix represents the specific measurement configuration, which dictates the valve position range and the required transducer compatibility for your specific application.

Is this module suitable for safety-critical applications?

Yes, the 3300/65 is designed for machinery protection, providing relay actuation for Alert and Danger conditions to trigger automated shutdowns or alarms when setpoints are exceeded.

Does this module require external power?

The module draws its operating power directly from the 3300 Series rack backplane. It features a low power consumption of approximately 2 W.
