Bently Nevada 330101-00-79-15-02-05 3300 Proximity Transducer

Technical Overview

The Bently Nevada 330101-00-79-15-02-05 is a high-precision eddy current sensor designed for non-contacting displacement and vibration monitoring. Part of the 3300 XL 8mm series, this probe provides a linear voltage output proportional to the gap between the tip and a rotating shaft. This specific configuration features an extended 7.9-inch case, engineered for deep-reach applications where the sensor must pass through thick machine housings to reach internal monitoring points.

Technical Specifications

The configuration of the 330101-00-79-15-02-05 is defined by its mechanical geometry and global hazardous area certifications, ensuring stability in aggressive industrial environments.

• Case Geometry: 7.9-inch (200.7 mm) overall case length with a 0.0-inch unthreaded portion, allowing for full-depth threading and precise mechanical gap adjustment.

• Cabling: 1.5-meter (4.9 ft) integral cable terminating in a gold-plated ClickLoc™ miniature coaxial connector.

• Material Science:

• Probe Tip: High-performance Polyphenylene Sulfide (PPS) for superior resistance to moisture and chemical corrosion.

• Probe Body: Corrosion-resistant AISI 303 or 304 Stainless Steel (SST).

• Performance Metrics:

• Linear Range: 2.0 mm (80 mils), typically starting at 0.25 mm (10 mils) from the target.

• Sensitivity: Standard 7.87 V/mm (200 mV/mil) when integrated with a matching 3300 XL Proximitor and extension cable.

• Operating Temp: -51 °C to +177 °C (-60 °F to +350 °F).

• Global Compliance: Multiple agency approvals including CSA, ATEX, and IECEx for Intrinsic Safety (Ex ia) and Non-Incendive (Ex nA) applications in Zone 0/1/2.

Key Features

• Vibration-Proof Connectivity: The proprietary ClickLoc™ connector system features a positive locking interface that prevents the signal cable from loosening under high-frequency machinery movement, ensuring data integrity.

• Thermal Stability: Engineered to maintain a stable linear output across a wide temperature spectrum, significantly reducing thermal drift compared to previous 3300 series models.

• Mechanical Resilience: The use of PPS for the tip and SST for the housing ensures the probe can withstand high-pressure environments (up to 50 psi) and exposure to industrial lubricants.

• System Interchangeability: Fully compatible with 3300 XL extension cables and Proximitors, and backward compatible with standard 3300 series components, allowing for flexible maintenance and upgrades.

• Critical Asset Protection: Ideal for monitoring radial vibration, axial thrust position, and speed (Keyphasor) on turbines, centrifugal compressors, and large-scale motors.
