Description

The Bently Nevada 330850-50-05 is a 3300 XL 25 mm Proximitor Sensor designed for high-precision vibration and position monitoring in industrial rotating machinery. This sensor utilizes advanced eddy-current technology to provide reliable displacement measurements. It is engineered to serve as a direct replacement for legacy 7200 25 mm, 7200 35 mm, and 25 mm DE Integral transducer systems, allowing for seamless system upgrades without requiring modifications to existing monitor configurations.

Features

• Versatile Mounting: Supports both high-density DIN-rail installation and traditional panel mount configurations.
• Enhanced Immunity: Improved RFI/EMI immunity ensures stable operation in environments with high-frequency radio signals, meeting European CE mark requirements without special mounting considerations.
• SpringLoc Terminals: Integrated SpringLoc terminal strips facilitate robust, tool-free field wiring connections.
• System Compatibility: Backwards compatible with existing 3300 XL series transducer system components.

Applications

• Power Generation: Continuous monitoring of critical auxiliary rotating equipment, including feed pumps and cooling fans.
• Oil & Gas: Monitoring of high-speed compressors in pipeline transportation and LNG processing plants.
• Petrochemical: Tracking wear and alignment of large-scale centrifuges, mixers, and pumps in refinery operations.
• Water Treatment: Bearing monitoring for large-scale pumps and industrial drying machinery.

Technical Specifications

Installation Guidelines

• Mounting: The unit can be mounted on a DIN-rail or via a traditional panel mount. Ensure the mounting surface is clean and provides adequate grounding.
• Wiring: Utilize the SpringLoc terminal strips for connections. No special tools are required; ensure wires are fully seated to maintain connection integrity.
• Environment: While the sensor features high RFI/EMI immunity, avoid routing signal cables in close proximity to high-voltage power lines or heavy electromagnetic interference sources.
• Handling: As a precision electronic component, handle with care to avoid ESD damage. Always power down the system before inserting or removing the module from the rack.
