Bently Nevada 330905-00-08-10-02-00 3300 NSv Proximity Probe

Product Overview

The Bently Nevada 330905-00-08-10-02-00 belongs to the high-precision 3300 NSv proximity probe series.

Engineers use eddy current technology to measure shaft vibration and position in tight spaces.

This probe delivers accurate shaft measurements inside centrifugal gas compressors and small steam turbines.

It features enhanced chemical resistance compared to older sensor designs.

Polyphenylene sulfide tip construction ensures long service life in harsh environments.

Technical Specifications

Installation Guide

• Mount the probe securely using proper torque specifications.
• Set the initial probe gap to 1.0 mm or 40 mils.
• Align the probe tip perpendicular to the target shaft surface.
• Maintain a target surface diameter of at least 13 mm.
• Tighten the M10x1 probe case to 11.3 N•m recommended torque.
• Do not exceed the maximum torque limit of 33.9 N•m.
• Keep the coaxial cable bend radius above 25.4 mm.

Commissioning & Maintenance Convenience

ClickLoc connectors enable quick cable attachment without special tools.

Engineers easily check probe health by measuring DC resistance between conductors.

Standard probe DC resistance measures 4.2 ± 0.5 ohms.

The robust design simplifies routine maintenance during plant turnarounds.

Compatibility & Engineering Advantages

This probe fully replaces legacy Bently Nevada 3300 RAM proximity probes.

It offers direct mechanical and electrical interchangeability without system recalibration.

The probe provides superior side-view performance over 3000-series 190 probes in narrow spaces.

Enhanced Viton O-ring seals provide reliable differential pressure sealing.

Agency Approvals & Certification Information

Option code -00 specifies standard non-agency approved applications.

Standard industrial installations do not require special hazardous area certifications.

Certified hazardous area options exist within the Bently Nevada catalog.

Model Selection & Comparison Guide

Selecting the correct case length prevents installation errors in deep machine housings.

Model 330905-00-08-10-02-00 features an 80 mm case length with 0 mm unthreaded length.

If your housing requires a 90 mm case and 50 mm unthreaded length, choose model 330905-00-09-05-02-00.

Both models share identical electrical performance and 1.0-meter cable lengths.

Always measure housing depth before selecting probe case specifications.

Global PLC Spare HUB's Insight & Field Experience

During a compressor overhaul, our engineering team resolved side-clearance signal distortion.

Standard probes suffered from side-wall interference inside narrow bearing counterbores.

Replacing legacy probes with 3300 NSv probes eliminated cross-talk interference completely.

The tighter magnetic field pattern preserved accurate voltage scale factors.

We recommend verifying target shaft metallurgy before final calibration adjustments.

Frequently Asked Questions

Q1: What is the recommended gap voltage setting during commissioning?

A1: Set the probe gap to 1.0 mm, which yields a -9.0 Vdc gap output.

Q2: Can engineers connect this probe directly to field wiring without an extension cable?

A2: No, you must connect this probe to a matching 3300 XL NSv Proximitor sensor.

Q3: How does chemical exposure affect the probe tip material?

A3: Polyphenylene sulfide material provides superior resistance against process gases and synthetic oils.

Q4: How do I select between different probe case lengths?

A4: Measure your bearing housing thickness to ensure full thread engagement and proper tip protrusion.
