Quick Detail

Description

The 330101-00-20-10-12-05 3300 XL 8 mm Proximity Probe is a premium-grade, intrinsically safe eddy current transducer, meticulously engineered by Bently Nevada in the USA for critical machinery health monitoring in demanding and regulated environments. As a fully integrated member of the industry-leading 3300 XL monitoring system, this proximity probe is designed to deliver precise, non-contact measurement of shaft vibration, axial position, and rotational speed. Its core operational principle converts minute physical displacements between its high-performance sensing tip and a conductive target into a stable, linear voltage signal, providing essential data for predictive maintenance and machinery protection of high-value assets like turbines, compressors, and large pumps.

A hallmark feature of this specific 3300 XL 8 mm Proximity Probe model is its combination of advanced safety certification and fluid-resistant design. The probe is pre-certified with major international hazardous area approvals, including CSA, ATEX, and IECEx, authorizing its direct and compliant installation in Zone 1/2 explosive atmospheres. Furthermore, it is equipped with an integrated FluidLoc cable, a specialized construction that creates a hermetic seal to prevent the migration of oils, coolants, and other process fluids along the cable core. This dual protection makes it an ideal solution for wet or washdown environments within hazardous locations, such as lube oil systems on offshore platforms or seal cavities in refinery pumps.

Applications

This probe is essential for monitoring critical rotating equipment in hazardous areas where fluid leakage is a concern, such as hydrocarbon gas compressors with wet seal systems or turbine-driven pumps in refineries. Its CSA/ATEX/IECEx certifications ensure safety compliance, while the integrated FluidLoc cable prevents lube oil or process fluid from traveling along the cable and creating an external leak path or damaging connections.

The compact 2-inch case length and 1.0-meter integrated cable make it an excellent choice for monitoring motors and pumps on skid-mounted packages or within crowded machinery modules. Its design allows for installation in standard mounting holes with sufficient cable length to reach a nearby junction box, all while providing the necessary safety certification and fluid sealing for such integrated industrial equipment.

It serves as a reliable upgrade or replacement sensor for legacy monitoring points on equipment in chemical processing or pharmaceutical plants, where both area classification (hazardous zones) and strict containment of process fluids are mandatory requirements for operational safety and environmental compliance.

Specifications

Competitive Advantage

1. Dual-Protection Design for Hazardous and Fluid-Exposed Environments

This probe uniquely combines major international hazardous area certifications (CSA, ATEX, IECEx) with an integrated FluidLoc cable. This provides a singular solution that addresses both explosion safety and fluid containment challenges, eliminating the need for separate sealing fittings or external protection for the cable entry. This integrated approach reduces installation complexity, enhances long-term reliability, and ensures compliance in high-risk, wet industrial settings.

2. Optimized Form Factor for Versatile and Space-Efficient Installation

Featuring a practical 2-inch case length with a fully threaded shank, the probe offers an ideal balance between mechanical robustness and installation flexibility. This compact form factor fits a vast majority of standard industrial mounting patterns without requiring adapters, simplifying sensor selection and inventory while ensuring a secure fit in space-constrained housings on pumps, motors, and gearboxes.

3. Factory-Integrated Reliability with Proven System Compatibility

Delivered as a complete, factory-sealed unit with a permanently attached cable and connector, the probe guarantees optimal signal integrity and mechanical durability from the first installation. Its guaranteed plug-and-play compatibility with the entire 3300 XL system ensures seamless integration, easy maintenance, and reliable performance, protecting investments in existing monitoring infrastructure and simplifying lifecycle management.
