Product Overview

The 330101-00-43-10-02-05 is a high-precision eddy current sensor from the Bently Nevada 3300 XL series, specifically configured for non-contacting vibration and position measurements. This 8 mm probe is engineered to translate the physical distance between its tip and a conductive target—typically a rotating shaft—into a proportional voltage signal. As a vital component of Turbine Supervisory Instrumentation (TSI), it provides critical data for the protection and condition monitoring of high-speed industrial assets such as gas turbines, compressors, and centrifugal pumps.

Technical Configuration and Build

The specific alphanumeric configuration of the 330101-00-43-10-02-05 model defines the following mechanical and electrical profile:

• Model Identification: 330101 (Standard 3/8-24 UNF Thread, No Armor)

• Unthreaded Body Length: 0.0 inches (Fully threaded case)

• Overall Case Length: 4.3 inches

• Total System Length: 1.0 Meter (3.3 feet)

• Connector Type: Miniature coaxial ClickLoc connector

• Hazardous Area Ratings: Multi-certified with CSA, ATEX, and IECEx approvals

• Calibration: Factory-set for AISI 4140 steel targets

• Thread Specification: 3/8-24 UNF-2A

Advanced Engineering and Durability

The 3300 XL 8 mm system is designed to thrive in rigorous industrial environments. This probe utilizes a Tip-to-Case seal that prevents oil and process fluids from wicking into the internal electronics. The sensing coil is encapsulated in high-performance Polyphenylene Sulfide (PPS) plastic, ensuring long-term thermal stability and resistance to chemical erosion.

By utilizing the 1.0-meter integrated cable design, this system minimizes potential signal degradation often found at intermediate cable junctions. The ClickLoc connector features gold-plated brass components and a mechanical locking mechanism that prevents unintended disconnection in high-vibration zones.

Functional Applications

This proximity transducer is a foundational tool for machinery health monitoring, serving several critical functions:

• Radial Vibration: Continuous monitoring of shaft movement within fluid-film bearings.

• Axial Position: Tracking thrust displacement to prevent rotor-to-stator contact.

• Keyphasor Signal: Providing timing and speed references for phase angle analysis.

• Simplified Integration: This "one-meter" probe can be connected directly to a Proximitor sensor in specific configurations, reducing the footprint in space-constrained housings.

• Backward Compatibility: Electrically compatible with legacy non-XL 3300 series 5 mm and 8 mm proximity systems.
