Bently 330910-05-10-02-00 3300 XL NSv Proximity Transducer

Overview

The Bently Nevada 330910-05-10-02-00 is part of the 3300 XL NSv Proximity Transducer System, designed for precise monitoring in applications with limited installation space. This system is ideal for centrifugal air compressors, refrigeration compressors, process gas compressors, and other machinery requiring tight space constraints. It enables accurate radial vibration, axial position, and tachometer measurements, especially for small shafts or reduced side-view areas.

Key Features

Compact Design: The 3300 XL NSv system fits in areas where conventional transducer systems fail due to space limitations, making it perfect for small target applications.
High Accuracy: It delivers high precision for radial vibration on shafts smaller than 51 mm (2 inches) or axial position on targets as small as 15 mm (0.6 inches).
Versatile Applications: Used primarily in fluid-film bearing machines, this system is ideal for measuring:
- Radial vibration and position
- Axial (thrust) position
- Tachometer and zero speed
- Phase reference signals (Keyphasor)
System Compatibility: The 3300 XL NSv replaces the 3300 RAM Transducer Systems and 3000-series or 7000-series 190 Transducer System, ensuring easy upgrades without major system changes.
