Bently Nevada 330101-00-27-15-02-00 3300 XL 8 mm Proximity Probe

Description

Designed for high-precision, non-contact dynamic and static measurements, the Bently Nevada 330101-00-27-15-02-00 proximity probe monitors vibration, position, and speed in critical rotating machinery. As a key sensing element within the 3300 XL 8 mm series, this eddy current probe converts distance variations between the probe tip and the target shaft into a proportional electrical signal when paired with a matching Proximitor sensor.

Features

• Optimized Thread Setup: Standard 3/8-24 UNF threaded body without unthreaded length for maximum physical mounting adjustability.
• ClickLoc Connector: Equipped with a miniature coaxial ClickLoc connector to ensure reliable, positive-locking signal contact without field-assembly failures.
• Rugged Material Engineering: Features a high-performance polyphenylene sulfide (PPS) tip capable of withstanding harsh, oil-rich turbine environments.
• Standard Cable Construction: Optimized cable flexibility without heavy armor, perfect for standard conduit runs.

Applications

• Steam and gas turbine shaft dynamic radial vibration monitoring
• Centrifugal compressor thrust (axial displacement) position tracking
• High-speed industrial fan and blower shaft dynamics analysis
• Boiler feed pump rotor position monitoring

Connections and Interfaces

The proximity probe uses a coaxial interface architecture to transmit raw RF and DC signals to the monitoring system:

Alternative Models & Compatibility

When deploying the 330101-00-27-15-02-00, ensure it is integrated within a matched Bently Nevada 3300 XL system. Probe electrical length (1.5 meters) must correspond with the appropriate extension cable (e.g., 3.5-meter extension cable) to construct a complete 5.0-meter system. Mixing components from 5.0-meter and 9.0-meter systems will result in severe calibration and output deviations.

Application Pitfalls & Engineering Notes

To prevent reading errors caused by magnetic field interference (cross-talk), do not route probe cables alongside high-voltage AC electrical lines. The probe tip must clear surrounding non-target metal components by at least three probe-tip diameters (24 mm) to avoid inductive coupling losses.

Commissioning & Wiring Tips

Before final coupling, clean the ClickLoc connectors with pure isopropyl alcohol. Once clean, lock the connector securely. To guarantee long-term operation inside fluid-sprayed areas, wrap the connector joint in oil-resistant fluoropolymer tape or protect it with Bently Nevada’s proprietary connector sleeve protectors.
