Quick Detail

Description

The 330703-000-178-10-02-00 3300 XL 11 mm Proximity Probe is a high-performance non-contact monitoring device developed by Bently Nevada, tailored to deliver precise displacement and vibration data for critical rotating machinery. As a key offering in the 3300 XL series, this 3300 XL 11 mm Proximity Probe serves as a seamless upgrade for legacy 7200-series 11 mm/14 mm transducer systems, combining modern performance with backward-compatible design to simplify industrial system transitions. Manufactured in the USA and supplied as factory-sealed original equipment, this 3300 XL 11 mm Proximity Probe embodies the reliability and accuracy that define Bently Nevada’s condition monitoring solutions, even in extreme operational environments.

Operating on eddy-current technology, the 330703-000-178-10-02-00 3300 XL 11 mm Proximity Probe converts micro-scale gap changes between its tip and conductive targets (e.g., turbine shafts) into a proportional voltage output. With a 4.0 mm (160 mils) linear range, this 3300 XL 11 mm Proximity Probe accurately measures shaft vibration, radial displacement, and axial movement—critical metrics for detecting early signs of mechanical issues like rotor imbalance, misalignment, or bearing wear. This precision is vital for preventing catastrophic equipment failures, reducing unplanned downtime, and enabling condition-based maintenance strategies in high-stakes industries.

Applications

The 330703-000-178-10-02-00 3300 XL 11 mm Proximity Probe is widely used in power generation facilities, where it monitors shaft vibration and displacement in steam turbines, gas turbines, and large generators. Its -52°C to +177°C operating temperature range ensures stability in both freezing outdoor substations and high-heat turbine enclosures, while the 4.0 mm linear range captures subtle mechanical anomalies that could lead to costly outages. By providing real-time rotor health data, this probe supports predictive maintenance programs that extend equipment lifespan and maintain consistent power supply.

In general manufacturing and industrial processing (e.g., paper mill rollers, conveyor system motors, and gearboxes), this 3300 XL 11 mm Proximity Probe delivers continuous vibration monitoring. Its 0 mm unthreaded length and 178 mm case length enable secure mounting in space-constrained machinery layouts, while the 1.0-meter cable simplifies integration with existing control systems. The probe’s low supply sensitivity and 50 Ω output resistance ensure reliable signal transmission amid factory floor electrical noise, helping manufacturers detect early component wear and reduce production downtime.

For marine and aerospace ground test rigs (e.g., propulsion system shafts, engine test equipment), the 330703-000-178-10-02-00 3300 XL 11 mm Proximity Probe provides precise position and vibration data. Its compact 2.5x2x115cm dimensions and 0.1kg weight minimize mechanical load on precision-critical setups, while the 69.9 pF/m extension cable capacitance reduces signal degradation over wiring runs. This probe’s ability to capture 4.0 mm linear range displacements helps engineers identify misalignment or wear in test equipment, ensuring accurate performance validation for marine and aerospace components.

Specifications

Competitive Advantage

1.Space-Optimized Design for Tight Installations

The 330703-000-178-10-02-00 3300 XL 11 mm Proximity Probe features a 0 mm unthreaded length and 178 mm overall case length, making it ideal for machinery with limited mounting space (e.g., compact turbine casings, dense pump assemblies). This design eliminates the need for extra clearance around the probe, simplifying installation in space-constrained industrial setups while maintaining stable positioning for accurate measurements.

2.Cost-Effective Performance for Non-Hazardous Zones

With an “Not required” agency approval option, this 3300 XL 11 mm Proximity Probe balances high performance with cost efficiency for non-hazardous industrial environments. It retains core 3300 XL series capabilities (4.0 mm linear range, stable signal transmission) without the premium of hazardous-area certifications, making it a budget-friendly choice for general manufacturing, power generation non-explosive zones, and test rig applications.

3.Seamless Legacy System Upgrades

As a direct replacement for 7200-series 11 mm/14 mm transducers, this 3300 XL 11 mm Proximity Probe simplifies upgrades to modern monitoring systems. It integrates with 3300 XL components (cables, proximitors) and is compatible with 3500 Monitoring Systems (with software configuration updates), eliminating the need for full infrastructure overhauls. This compatibility protects existing investments while unlocking the enhanced performance of the 3300 XL platform.
