Quick Detail

Description

The Bently Nevada 330102-00-52-10-02-00 3300 XL 8 mm Proximity Probe is a premium-grade eddy current transducer engineered to deliver unmatched accuracy and reliability for machinery condition monitoring in the world's most demanding industrial environments. This specific configuration is distinguished by its 1.0-meter (3.3 feet) total probe length and a substantial 8.0-meter (26.2 feet) integrated standard cable, providing exceptional reach and flexibility for installations where the sensor must be positioned far from the signal conditioner. The probe is equipped with a secure miniature coaxial ClickLoc connector, further protected by a dedicated connector protector, ensuring a vibration-proof and environmentally sealed connection to the extension cable and, ultimately, the Proximitor sensor.

At its core, the probe utilizes a highly durable Polyphenylene Sulfide (PPS) sensing tip, renowned for its excellent electrical insulation and resistance to a wide range of industrial chemicals and lubricants. This tip is permanently bonded to the robust AISI 303 or 304 stainless steel case using Bently Nevada's proprietary manufacturing process, guaranteeing mechanical integrity and preventing tip separation even under severe vibration and thermal stress. With a generous linear range of 3 mm, this 8 mm probe excels at precisely measuring both dynamic rotor vibration and static axial position on critical assets such as turbines, compressors, and large pumps. Its electrical performance is characterized by a stable 45 Ω output resistance and minimal supply sensitivity (<2 mV/V), ensuring the signal faithfully represents the gap measurement regardless of minor fluctuations in the system's -17.5 Vdc to -26 Vdc power supply.

Applications

This extended-reach probe is ideal for monitoring critical vibration and position on large steam turbines and gas compressors in power generation and oil & gas facilities. Its 8.0-meter integrated cable allows the probe to be installed directly on the turbine casing while the signal cable is routed over significant distances to a remote monitoring cabinet, eliminating the need for intermediate junction boxes and preserving signal integrity for accurate thrust bearing and radial vibration measurement.

For large industrial motors, fans, and pumps where sensor mounting points are difficult to access or located in high-temperature zones, this probe provides a reliable solution. The combination of a 1.0-meter probe body and a long 8.0-meter cable offers installation flexibility, while its wide operating temperature range ensures stable performance even when the cable is routed through hot environments, enabling continuous condition monitoring for predictive maintenance programs in industries like metals, mining, and chemical processing.

The probe is perfectly suited for Keyphasor (speed reference) applications on large rotating equipment. Its precise and stable output, delivered through the ruggedized ClickLoc connection, provides a clean, reliable once-per-revolution pulse that is essential for vibration phase analysis, balancing, and torsional monitoring. The long cable length facilitates installation where the keyphasor module is located far from the measurement point on the shaft, ensuring a simple and robust installation for accurate speed and phase reference data.

Specifications

Competitive Advantage

1.Extended-Reach Design for Complex Installations

The unique combination of a standard probe with an integrated 8.0-meter cable provides a significant installation advantage. This design simplifies wiring in large machinery trains by reducing the number of cable splices and connection points, which are potential failure sources. It offers engineers greater flexibility in locating monitoring racks and reduces installation time and material costs compared to using a standard probe with a separate, shorter extension cable.

2.Superior Connector Durability for High-Vibration Environments

Featuring a miniature coaxial ClickLoc connector with an additional connector protector, this probe offers unmatched connection security. This dual-layer protection system ensures the electrical connection remains intact despite severe machinery vibration, accidental impacts, or exposure to moisture and contaminants. This robustness drastically reduces the risk of signal interruption—a common cause of false alarms in machinery protection systems—and enhances long-term reliability.

3.Enhanced Linear Range for Broad Measurement Capability

With an extended linear range of 3 mm, this probe provides a wider measurement window compared to standard 2 mm linear range probes. This allows for monitoring applications with larger expected shaft movement or eccentricity, providing a greater safety margin and more detailed data for diagnostic analysis. This enhanced range makes it particularly valuable for machinery with larger clearances or for applications requiring monitoring of both very small and relatively large displacements with a single sensor.
