Quick Detail

Description

The 330703-020-110-10-01-05 3300 XL 11 mm Proximity Probe represents a sophisticated evolution in large-diameter eddy current sensing, engineered by Bently Nevada to deliver superior performance for monitoring heavy industrial machinery. As an integral component of the advanced 3300 XL monitoring system, this proximity probe is specifically designed to provide exceptionally accurate and reliable measurements of shaft vibration, axial position, and rotational speed on large-bore rotating equipment such as hydro turbines, large compressors, and heavy-duty generators. Its primary function is to linearly convert the physical gap between its robust sensing face and a conductive target into a stable, high-fidelity voltage signal, enabling precise condition monitoring and predictive maintenance.

A defining characteristic of this 3300 XL 11 mm Proximity Probe is its extended 4.0 mm linear range, which offers a significantly wider measurement window compared to standard 8 mm probes. This makes it ideally suited for applications involving larger shaft movements or where greater installation clearance is required. The probe is constructed for extreme durability, featuring a rugged case with a 20 mm unthreaded length and a 110 mm overall case length, providing versatile mounting options in various housings and adapters. It is supplied as a complete, factory-integrated unit with a 1.0-meter (3.3 feet) standard cable and a secure Miniature coaxial ClickLoc connector, which is further protected by a connector protector to ensure vibration resistance and environmental sealing in harsh installations.

Applications

This probe is essential for vibration and position monitoring on large-diameter, slow-speed rotating assets like hydroelectric turbine shafts and large induced draft (ID) fans, where its extended 4.0 mm linear range is critical for accurately capturing significant shaft excursions and low-frequency vibration components that smaller probes cannot adequately measure.

Its robust construction, wide temperature tolerance, and hazardous area certifications make it suitable for deployment in extreme environments such as mining draglines, offshore platform compressors, and sinter plants, where equipment is subjected to severe thermal cycles, high vibration, and potentially explosive atmospheres.

The probe serves as a key upgrade component for modernizing legacy monitoring systems that originally used larger-diameter transducers. Its compatibility with the 3300 XL platform allows for a performance-enhanced replacement, improving diagnostic accuracy and system reliability for older turbines and compressors without requiring complete system overhauls.

Specifications

Competitive Advantage

1. Extended Measurement Range for Large Machinery Dynamics

Featuring a substantial 4.0 mm linear range, this 11 mm probe provides a significantly wider measurement window than standard 8 mm probes. This extended range is critical for accurately monitoring the larger absolute displacements and vibrations typical of heavy-duty, large-bore machinery such as hydro turbines and slow-speed compressors, enabling more comprehensive fault detection and machinery protection.

2. Engineered for Ultra-Harsh Operational Environments

Built to withstand extreme conditions, the probe operates reliably across a vast temperature spectrum from -52°C to +177°C. Combined with its rugged mechanical design, integrated connector protector, and multiple hazardous area approvals, it delivers unmatched durability and safety compliance for the most challenging installations in sectors like mining, metals processing, and offshore energy.

3. Optimized Signal Integrity and System Integration

With precise electrical specifications—including a stable 50 Ω output resistance and supply sensitivity under 2 mV/V—the probe ensures high-fidelity signal transmission resistant to power supply fluctuations. Its factory-integrated cable with ClickLoc connector guarantees plug-and-play compatibility within the 3300 XL system, simplifying installation, ensuring performance, and reducing total cost of ownership through easy maintenance and component interchangeability.
