Quick Detail

Description

The 3300 XL NSv Proximity Probe (Model 330901-00-12-70-01-05) is a high-precision eddy current sensor specifically engineered for advanced industrial automation and condition monitoring applications. Designed for centrifugal air compressors, refrigeration compressors, and process gas compressors with restricted installation spaces, this 3300 NSv Proximity Probe offers superior radial and axial vibration measurement capabilities on small shafts and limited side-view areas. Featuring a 1.2-inch overall case length, a 7-meter (23-foot) miniature coaxial ClickLoc cable with connector protector, and a 1/4-28 UNF probe thread, the 3300 NSv provides reliable monitoring even in compact or high-temperature environments from -52°C to +177°C (-62°F to +351°F). Its polyphenylene sulfide (PPS) probe tip, combined with an AISI 304 stainless steel case, ensures high chemical resistance and mechanical durability. The probe delivers a linear range of 1.5 mm (60 mils) with a recommended gap setting of 1.0 mm (40 mils), an output resistance of 50 Ω, and minimal supply sensitivity (<2 mV change per volt input variation), making it ideal for precise radial position, axial position, tachometer, and phase reference measurements in automated industrial systems. Fully compatible with existing 3300 RAM probes and extension cables, this 3300 NSv Proximity Probe supports easy system upgrades and seamless integration into legacy Bently Nevada monitoring networks.

Applications

Radial Vibration Measurement: Optimized for small shafts <51 mm (2 in), providing precise radial vibration data critical for high-speed compressors.
Axial (Thrust) Position Measurement: Accurately measures axial motion on flat targets <15 mm (0.6 in) for automated monitoring of turbine and compressor thrust bearings.
Tachometer and Zero Speed Detection: Enables real-time rotational speed monitoring and zero-speed verification in industrial automation systems.
Phase Reference (Keyphasor) Signal Generation: Provides stable phase reference signals for synchronizing advanced process control and predictive maintenance systems.
Small-Space Industrial Installations: Ideal for counter bore, side-view, or rear-view restricted environments where standard 3300 XL probes cannot be installed.

Specifications

Competitive Advantage

High Temperature and Chemical Resistance: PPS probe tip and stainless steel case enable operation in -52°C to +177°C with superior chemical resistance compared to legacy 3300 RAM probes.
Enhanced Side-View Capability: Optimized for tight spaces, allowing precise monitoring where standard 5 and 8 mm Bently Nevada XL probes are impractical.
Mechanical and Electrical Compatibility: Seamless upgrade from 3300 RAM or 3000/7000-series systems using existing extension cables and Proximitor Sensors.
Robust Connector and Cable Design: ClickLoc connectors with 220 N pull strength, TipLoc molding, and CableLoc system prevent disconnection and signal loss in harsh industrial conditions.
Short Linear Range Optimization: 1.5 mm linear range allows precise measurement on small targets while maintaining high output accuracy (7.87 V/mm), outperforming 3000-series 190 transducers.
