330903-00-06-10-02-05 Bently Nevada 1.0m Eddy Current Probe

Technical Specifications

Product Overview

The Bently Nevada 330903-00-06-10-02-05 is a brand new, original factory-packed 3300 NSv Proximity Probe designed for advanced shaft vibration and position monitoring in process compressors. Weighing a lightweight 0.15 kg, this premium sensor features a 60mm case length with an unarmored M8 × 1 metric thread housing, a 1.0-meter integrated FEP insulated cable, and an elite multiple agency approval rating. It delivers complete mechanical and electrical backward compatibility with legacy 3300 RAM setups while introducing upgraded chemical resistance and superior side-view sensing characteristics.

Core Technical Advantages

• Upgraded Process Resilience: Outfitted with a Polyphenylene sulfide (PPS) tip and an integrated Viton O-ring pressure seal to withstand aggressive gases and dynamic environments.
• Optimized Target Side-View Profile: Outperforms legacy 3000-series 190 sensors, minimizing cross-talk and side-space interference when constraints force a narrow mounting footprint.
• Stable Scale Linearization: Provides a nominal 7.87 V/mm (200 mV/mil) Incremental Scale Factor with a minimal linearity deviation of less than ±0.06 mm across the active 1.5 mm tracking zone.
• ClickLoc Coaxial Connection: This compact 0.15 kg instrument features a miniature coaxial ClickLoc connection terminal, optimizing transmission over 75 Ω coaxial wiring.

Installation Guide

Mount the M8 × 1 probe case into the machine bracket, observing a maximum thread engagement depth of 12 mm. Set the baseline air gap to the recommended 1.0 mm (40 mils) setting from the shaft target surface (minimum target area diameter of 8.9 mm, recommended 13 mm). Using standard tools, tighten the 0.15 kg case structure to the recommended installation torque of 5.1 N·m (maximum rated at 7.3 N·m). For the connector-to-connector linkage, remain within finger tight limits up to a maximum torque of 0.56 N·m. Ensure the FEP probe cable maintains a minimum bend radius of 25.4 mm during layout.

Technical FAQs

Q1: Can the 330903-00-06-10-02-05 probe directly replace an older 3300 RAM system probe?
A1: Yes. The 3300 NSv probe body and its extension cables are both mechanically and electrically compatible and interchangeable with previous Bently Nevada 3300 RAM series hardware.

Q2: What field wiring specifications are recommended for long-distance runs?
A2: It is highly recommended to use a three-conductor shielded triad cable (0.2 to 1.5 mm² or 16 to 24 AWG). The maximum permissible distance between the Proximitor sensor and the monitor rack is 305 meters (1,000 feet).

Q3: How does a small shaft target size affect the precision of this proximity sensor?
A3: Axial measurements on shaft diameters smaller than 13 mm (0.5 in) will generally alter the scale factor. To limit this effect and safeguard signal accuracy, it is best to reduce the operating gap between the probe tip and the target.
