Description

The Bently Nevada 330876-01-90-00-00 is a high-performance 3300 XL 50 mm Proximity Probe designed for critical rotating machinery. As a core component of the 3300 XL 50 mm Transducer System, this eddy-current sensor is engineered for precise measurement of differential expansion, shaft position, and vibration in large steam turbines and turbine-generator units. Its large 50 mm sensing coil provides an extended linear range, ensuring accurate data acquisition during critical operational phases such as startup, shutdown, and significant load changes.

Features

  • 3300 XL 50 mm proximity probe with 1/2-20 UNF thread.
  • Side-exit case style featuring two 1/4-20 mounting holes for flexible installation.
  • 90-inch (2286 mm) total system length.
  • High-temperature FluidLoc cable construction to prevent moisture wicking.
  • Gold-plated ClickLoc connectors for superior corrosion resistance and signal integrity.
  • Designed for operation in temperatures up to 200 degC (392 degF) continuous.

Applications

  • Differential expansion (DE) and rotor expansion (RX) monitoring.
  • Large steam turbine generator shaft position sensing.
  • High-temperature industrial turbine environments.
  • Applications requiring long-range displacement measurement.

Installation Guidelines

  • Thread Engagement: Ensure internal matching threads do not exceed 1.5 times the nominal thread diameter to prevent binding.
  • Sideview Clearance: Maintain an open radius around the 50 mm probe tip to avoid interference with surrounding metallic structures.
  • Target Requirements: Use a Bently Nevada AISI 4140 steel target with a minimum diameter of 102 mm (4.0 inches) to maintain specified accuracy.
  • Securing: Tighten the locknut using the predrilled safety wire holes to ensure the probe remains fixed against machine vibration.
  • Connector Care: Use the provided connector protectors and installation tool to keep contacts free of contamination during routing.
