330105-02-12-05-02-00 Bently Nevada New 3300 XL 8 mm Probe

Product Overview

The 330105-02-12-05-02-00 is a high-accuracy eddy current proximity transducer.

It belongs to the industry-standard Bently Nevada 3300 XL 8 mm reverse mount probe series.

Engineers install this probe externally through housing walls for limited-access applications.

It measures dynamic shaft vibration and axial position in critical rotating machinery.

Polyphenylene sulfide tip construction provides robust resistance against aggressive process contaminants.

Configuration Breakdown

• Part Number: 330105-02-12-05-02-00
  • Base Model Option (-02-12): 3300 XL 8 mm reverse mount probe with standard thread housing.
  • Total Cable Length Option (-05): 0.5 meter (1.6 feet) FEP insulated coaxial lead cable.
  • Connector Type Option (-02): Miniature coaxial ClickLoc connector for vibration-proof locking.
  • Agency Approval Option (-00): Standard non-agency approval configuration for non-hazardous zones.

Technical Specifications

Target Machinery & Diagnostic Capabilities

• Centrifugal Compressors: Tracks axial position and radial vibration in restricted housing spaces.
• Gas & Steam Turbines: Delivers real-time shaft orbit diagnostics under elevated operating temperatures.
• High-Speed Gearboxes: Monitors journal bearing oil film thickness and early shaft misalignment.
• Diagnostic Integration: Feeds dynamic signals to Proximitor sensors for continuous asset monitoring.

Selection Guide & Technical Comparison

Choose the 330105-02-12-05-02-00 for compact internal routing requiring a 0.5-meter probe lead.

If your installation demands China regional approvals and armored cables, choose model 330105-02-12-20-12-CN.

Model 330105-02-12-20-12-CN features a 2.0-meter length with flexible stainless steel armor.

Always verify total system cable length to ensure proper electrical tuning with the Proximitor sensor.

Global PLC Spare HUB's Insight & Field Experience

Reverse mount probes eliminate machine disassembly during emergency sensor replacements.

On an ethylene plant turbo-compressor, technicians replaced a damaged sensor from outside the casing.

Installing the 330105-02-12-05-02-00 probe restored full axial displacement monitoring in 30 minutes.

Always torque the probe case to 7.5 N•m to prevent thread galling while ensuring secure mechanical seating.

We advise measuring probe DC resistance before finalizing machine cover seals.

Frequently Asked Questions

Q1: What is the primary operational benefit of reverse mount probe design?

A1: Technicians install reverse mount probes through external housing threads without removing heavy machine covers.

Q2: How does extreme cold affect the internal probe pressure seal?

A2: Temperatures below -34°C can cause premature failure of the Viton pressure seal surrounding the probe body.

Q3: What electrical test verifies probe lead integrity prior to startup?

A3: Measure DC resistance across conductors; healthy 0.5-meter probes read 7.45 ± 0.50 ohms.

Q4: How do I select total cable length when building a 3300 XL transducer loop?

A4: Total length of probe lead and extension cable must match the Proximitor rating, typically 5.0m or 9.0m.

Q5: Why is ClickLoc connector locking mechanism essential for turbomachinery?

A5: ClickLoc connectors lock keyways firmly, preventing signal dropouts caused by high-frequency machine vibration.
