Product Overview

The Bently Nevada 330851-02-000-040-50-00-05 is a high-performance 25mm proximity probe designed for mission-critical machinery protection. This eddy current displacement sensor features a 40mm case length with full M30x2 thread engagement, making it ideal for monitoring large-shaft vibration and axial position in space-constrained environments. With its PEEK sensing tip and triaxial cable design, it offers unmatched signal stability and survivability in the most demanding industrial and marine applications.

Technical Configuration

  • Model Number: 330851-02-000-040-50-00-05
  • Probe Diameter: 25 mm High-Precision Tip
  • Thread Option: M30 x 2 Metric Threads (02)
  • Unthreaded Length: 0 mm Full Thread (000)
  • Case Length: 40 mm Mid-Sized Case (040)
  • Total Length: 5.0 Meters / 16.4 Feet (50)
  • Armor Option: Standard No Armor (00)
  • Agency Approvals: ATEX/IECEx/CSA Multi-Approval (05)

Technical Specifications

Linear Range 12.7 mm (500 mils) Max Survival Temp 250°C (Peak)
Corrosion Class ISO 12944-C5M (Coastal) Cable Impedance 75Ω Triaxial
Compliance ATEX/IECEx Zone 0, ABS Marine, ISO 10816-3 Class 4

Installation & Maintenance

1. Mechanical Integrity: The 330851-02-000-040-50-00-05 features a high 163N•m torque capacity. Ensure the mounting surface is perpendicular to the shaft to maintain the ±5μm sensing precision of the PEEK tip.

2. Gapping and Calibration: For proper measurement of the 12.7mm linear range, this probe must be paired with a 3300 XL 25mm Proximitor. Use a gap-to-voltage conversion tool to set the center point at -10.0 Vdc.

3. Severe Environments: This probe is rated for ISO 12944-C5M coastal corrosion resistance. In marine or chemical plants, verify that the 75Ω triaxial cable connectors are secured and free from moisture to prevent signal drift.

Engineering Advantages

The 3300 XL 25mm system is the global standard for axial displacement monitoring on large steam turbines. The 330851-02-000-040-50-00-05 provides a critical advantage with its 250°C peak survival rating, allowing for continued operation during emergency thermal transients. Its ABS Type Approval ensures it meets the vibration and environmental rigor required for marine propulsion systems and offshore platforms, while the 50m/s² vibration rating guarantees data accuracy under heavy industrial loads.

Technical FAQs

Q1: What is the benefit of the 40mm case length?
A1: The 40mm length is a versatile "mid-size" that provides enough case depth for secure mounting while remaining short enough to fit inside most standard machinery bearing housings.

Q2: Can this probe handle sub-zero temperatures?
A2: Yes, it is rated for immediate cold-start operation at -35°C, making it suitable for unheated outdoor installations in cold climates.

Q3: Is this probe intrinsically safe?
A3: Yes, the "05" suffix indicates multi-agency approvals including ATEX and IECEx Zone 0, allowing for safe use in explosive atmospheres when used with the appropriate safety barriers.
