330908-00-55-05-02-00 Bently Nevada 3300 NSv Eddy Current Probe

Product Overview

The 330908-00-55-05-02-00 is a high-precision industrial proximity probe belonging to the Bently Nevada 3300 NSv (Narrow System) transducer series. Specifically engineered for fluid-film bearing vibration and position monitoring, this eddy current sensor is optimized for machinery with tight clearance constraints or small shaft diameters where standard probes cannot fit. Featuring a rugged stainless steel housing, specialized FEP-jacketed coaxial cabling, and an ultra-lightweight design weighing between 14g to 150g (depending on the thread-to-cable distribution), the probe converts physical distance into an accurate electrical signal for continuous asset health tracking.

Core Technical Advantages

• Narrow Gap Optimization: Designed with a compact tip diameter to achieve exceptional linearity and cross-talk suppression in confined machinery pathways and small target areas.
• ClickLoc Interconnect System: Utilizes an integrated ClickLoc miniature coaxial connection mechanism (02 Code), providing an IP67-rated moisture-resistant lock that prevents accidental disconnection from vibration.
• Superior Signal Stability: Demonstrates an ultra-low calibration drift rate of just ±0.25% over 1,000 hours of continuous operation, ensuring sustained measurement integrity without frequent re-gapping.
• High-Durability Sealing: Equipped with a high-performance Viton O-ring system that maintains a 98% compression retention rate even after undergoing 10,000 extreme thermal operational cycles.

Technical Specifications

Engineering Installation & Maintenance

• Torque Constraints: When installing the 3/8-24 UNF threaded body into the machine housing, apply a recommended standard seating torque of 11.3 N·m. Do not exceed a maximum limit of 33.9 N·m to protect the internal coil assemblies from stress deformation.
• Cable Handling Precautions: To maintain shielding performance and prevent coaxial signal degradation, ensure that the integral FEP cable maintains a minimum structural bend radius of 30° during routing. The lightweight 14-150g profile ensures minimal strain on mounting fixtures under high-vibration conditions.
• Environmental & Storage Guidelines: While operational across high thermal ranges up to 1.5°C/min change rates, keep the probes stored in areas above -34°C (-30°F) to ensure the Viton sealing components remain flexible and crack-free.

Why Choose This Model

• Centrifugal Machinery Fit: The compact, narrow system geometry makes it the industry standard for small steam turbines, high-speed compressors, and specialized turbochargers.
• Harsh Environment Protection: High-resistance FEP cable insulation provides superior resilience against chemical erosion, hot lubricating oils, and aggressive synthetic machine fluids.
• Accurate Calibration Matching: Part of a fully matched Bently Nevada loop configuration, providing reliable millivolt-per-mil or millivolt-per-micrometer voltage tracking when paired with a 3300 NSv Proximityor sensor block.

Technical FAQs

Q1: What specific options does the configuration code 00-55-05-02-00 represent?
A1: It break downs as follows: 00 = unthreaded length option, 55 = 5.5-inch case length, 05 = 0.5-meter integral cable length, 02 = ClickLoc coaxial connector with miniature boot configuration, and 00 = standard agency approval profiling.

Q2: Can this 3300 NSv probe be directly cross-connected with standard 3300 XL 5mm/8mm extension cables?
A2: No. The 3300 NSv series utilizes different electrical characteristics and matching impedances compared to the standard 3300 XL lines. It must be paired strictly with 3300 NSv specific extension cables and Proximityor modules.

Q3: Is the integrated Viton O-ring capable of handling high pressure differentials?
A3: Yes, the integrated Viton seal configuration is explicitly pressure-differential rated to prevent process gas or hot machine oil from escaping past the probe installation mounting bore.
