Description

The Bently Nevada 330101-00-08-10-11-05 is a high-precision 3300 XL 8 mm proximity probe configured with a fully threaded 0.8 inch overall case length and zero unthreaded length. Designed for demanding industrial applications where oil, moisture, or other process fluids are present, this specific variant features a specialized 11 connector option. This option equips the probe with a FluidLoc coaxial cable and an integrated ClickLoc connector protector. This configuration ensures that liquids cannot migrate through the cable interior or breach the connection point. In addition, the probe includes standard CSA, ATEX, and IECEx hazardous area approvals (05 option) for intrinsically safe installations, making it an essential component for critical machinery protection where environmental sealing and hazardous area compliance are paramount.

As part of the Bently Nevada 3300 XL series, this proximity probe operates on the eddy-current measurement principle to provide non-contact, highly accurate vibration and shaft position data. It integrates seamlessly into 3300 XL monitoring systems, pairing with a 330180 series Proximitor sensor and a corresponding standard extension cable to deliver continuous machinery health diagnostic data to 3500 rack systems or other machinery protection monitors. The robust mechanical design features a patented TipLoc molding method that forms an extremely secure bond between the 8 mm probe tip and the stainless steel body, ensuring reliable performance in harsh rotating machinery environments such as gas turbines, steam turbines, compressors, and high-speed pumps.

Features

• FluidLoc Cable Protection: The FluidLoc cable construction prevents oil, process lubricants, and other fluids from migrating along the interior of the cable, ensuring environmental sealing and protecting terminal housings.
• Integrated Connector Protector: Features a factory-installed connector protector over the gold-plated miniature ClickLoc coaxial connector, providing robust shielding against moisture and industrial contaminants.
• Fully Threaded Standard Case: Designed with a 0.8 inch overall case length and a 0.0 inch unthreaded length, allowing maximum adjustment and stability in compact bearing housing mountings.
• High-Strength Construction: Utilizes a patented TipLoc molding process to bond the 8 mm probe tip securely to the stainless steel case, plus a CableLoc design with 330 N (75 lbf) pull strength.
• Hazardous Area Compliance: Certified with international CSA, ATEX, and IECEx agency approvals for safe operation in intrinsically safe and division/zone-rated industrial areas.
• Reliable Eddy-Current Performance: Provides exceptionally accurate non-contact displacement measurements for critical shaft vibration and axial position monitoring.

Applications

• Steam and gas turbine shaft vibration monitoring
• Compressor and turbine rotor axial displacement measurement
• High-speed industrial pump shaft position tracking
• Gearbox bearing wear analysis and machinery protection
• Permanent mounting inside bearing housings exposed to oil and moisture

Installation Guidelines

• Probe Gapping: Mount the proximity probe using the proper mechanical gap corresponding to the system's electrical calibration, typically aligned via the Proximitor sensor output voltage.
• Connector Handling: Ensure that the miniature ClickLoc coaxial connectors are tightened finger-tight only. Standard ClickLoc connections will click when fully engaged; do not use pliers or other tools on these connectors unless mating to a non-XL stainless steel connector.
• Cable Routing: Secure the FluidLoc cable and avoid bending radii tighter than the minimum recommended limits. Keep cable paths isolated from high-voltage wiring to minimize electromagnetic interference.
• Grounding: Properly shield and ground the overall monitoring chain in accordance with standard industrial vibration monitoring procedures (such as Bently Nevada drawing 141092).

Compliance and Certifications

• CSA, ATEX, IECEx: Approved for hazardous area installations under Intrinsically Safe (ia) and Non-Incendive/Increased Safety (nA, ec) protection classes when installed per manufacturer control drawings.
• CE Mark: Fully compliant with European EMC directive requirements when paired with matching 3300 XL Proximitor sensors.
• RoHS: Complies with standard restriction of hazardous substances directives.
