The Bently Nevada 330780-91-05 is a key component of the 3300 XL 11 mm Proximitor Sensor system, designed for precise non-contact measurement of vibration and displacement in industrial machinery.

Applications

• Measures axial position (thrust) for machine health assessment.
• Tracks ramp differential expansion in steam turbines.
• Monitors rod position or drop in reciprocating compressors.
• Provides tachometer and zero-speed readings.
• Generates phase reference (Keyphasor) signals.

Technical Specifications

• Sensor type: Proximitor (Eddy-current)
• Target diameter: 11 mm (optimized for extended linear range)
• Output: 3.94 V/mm (100 mV/mil) for high-resolution signal processing
• Frequency range: 0 to 8 kHz, suitable for various vibration monitoring needs
• Mounting options: DIN rail or panel mount for flexible installation

Benefits

• Replaces legacy systems: Upgrades existing 7200-series 11 mm and 14 mm transducer systems seamlessly.
• Enhanced performance: Offers superior accuracy and a wider linear range compared to standard 8 mm sensors.
• Improved versatility: DIN rail mounting enables space-saving installation in high-density environments.
• Robust design: Provides excellent resistance to radio frequency interference (RFI) for reliable operation.
