Quick Detail

Description

The 330101-00-44-10-02-05 3300 XL 8 mm Proximity Probe represents the pinnacle of precision in non-contact displacement and vibration monitoring for critical rotating machinery. Engineered by Bently Nevada, a global leader in asset protection, this proximity probe is a core component of the renowned 3300 XL monitoring system, designed to deliver unparalleled accuracy in measuring shaft radial vibration, axial position, and dynamic runout. This specific configuration is defined by its 8 mm probe diameter, comprehensive Multiple Approvals (CSA, ATEX, IECEx), and a factory-integrated 1.0 meter cable terminated with a reliable miniature coaxial ClickLoc connector for secure and quick installation.

Constructed for maximum durability in severe service environments, the probe features a rugged AISI 303 or 304 stainless steel case and a probe tip made of advanced Polyphenylene Sulfide (PPS) material. This construction ensures exceptional resistance to corrosion, chemical attack, and mechanical wear, which is critical in industries like oil and gas and power generation. The probe's exceptional Operating Temperature Range from -55°C to +177°C guarantees stable, drift-free performance in the most extreme thermal conditions, from freezing cold starts to high-temperature turbine pedestals.

A key feature of the 330101-00-44-10-02-05 model is its 4.4-inch overall case length with 0 inches of unthreaded length (option -44-), allowing for a flush-mount installation that is optimal for applications with strict space constraints near bearing housings. The probe provides a precise 2 mm linear measurement range, generating high-fidelity signals essential for detecting incipient machine faults such as imbalance, misalignment, and bearing degradation.

Applications

This probe is the ideal solution for continuous online monitoring of radial shaft vibration in high-speed rotating equipment such as steam turbines, gas turbines, centrifugal compressors, and large pumps. Its 8 mm diameter and precise 2 mm linear range enable the detection of dynamic shaft motion with high resolution, crucial for identifying early signs of imbalance, misalignment, and fluid-induced instabilities. The integrated 1.0-meter cable with ClickLoc connector facilitates easy routing and connection in crowded junction boxes.

Certified with CSA, ATEX, and IECEx approvals, this probe is designed for safe and compliant operation in hazardous locations found in refineries, offshore platforms, and chemical processing plants. Its robust stainless steel construction and PPS tip withstand exposure to hydrocarbons, process chemicals, and saline environments. This makes it exceptionally reliable for critical measurements on equipment like turboexpanders and reciprocating compressors, where accurate shaft position data is vital for mechanical integrity and safety system interlocks.

The probe is extensively used for precise axial thrust position monitoring to protect turbines and compressors from damaging rotor-to-stator contact. Its compact 4.4-inch overall length allows installation in the confined spaces of thrust bearing assemblies. Excellent electrical characteristics, including low output impedance and high immunity to power supply variations, ensure the signal remains stable over long cable runs to monitoring systems. This enables seamless integration into plant Distributed Control Systems (DCS) for continuous machine protection and performance optimization.

Specifications

Competitive Advantage

1. Global Hazardous Area Certification and Extreme Durability

The probe's Multiple Approvals (CSA, ATEX, IECEx -05 option) provide a single, globally accepted solution for explosive atmospheres, simplifying regulatory compliance for multinational operations. Coupled with an extreme operating temperature range (-55°C to +177°C) and a housing made of corrosion-resistant stainless steel, it offers unmatched resilience. This combination ensures long-term reliability and reduces lifecycle costs in the world's most demanding environments, from Arctic installations to hot, corrosive offshore platforms.

2. Precision-Engineered Form Factor for Optimal Measurement

The model's -44- option specifies a 0-inch unthreaded length and a 4.4-inch overall case length. This design is engineered for precise, flush mounting into standard probe holes, which is critical for establishing the correct initial gap to target and achieving optimal performance within the specified 2 mm linear range. The 8 mm diameter is an industry-standard size that provides the ideal balance of mechanical robustness and installation flexibility in tight bearing housing geometries.

3. Superior Signal Integrity and Seamless System Integration

Featuring a miniature coaxial ClickLoc connector, the probe ensures a vibration-resistant, positive-lock connection that prevents accidental disconnection and reduces installation time. Its electrical design, characterized by low output resistance and excellent supply noise immunity, guarantees a clean, stable signal that is resistant to degradation from EMI/RFI. As part of the 3300 XL ecosystem, it maintains full backward compatibility with existing Bently Nevada monitoring frameworks, allowing for straightforward upgrades or expansions without requiring costly system overhauls, thereby protecting legacy investments.
