Description

The Bently Nevada 330101-00-77-15-12-05 is an 8 mm proximity probe belonging to the 3300 XL 8 mm Proximity Transducer System family. Specifically configured for demanding oil-splash and high-fluid environments, this variant incorporates patented FluidLoc cable construction. The FluidLoc design blocks lubricating oils and other process liquids from migrating along the inside of the cable to the dry area of the machine. It is designed with a fully threaded 7.7-inch brass/stainless steel case, meaning it has a 0.0-inch unthreaded length, making it ideal for deep-threaded mounting ports on bearing housings.

Working on the eddy-current operating principle, this non-contact probe provides precise, continuous measurements of vibration and shaft displacement. It is designed to work as part of a complete 3300 XL loop, connecting via its miniature ClickLoc coaxial connector to a 3300 XL extension cable and a Proximitor sensor for routing signals to a 3500 rack or other TSI safety-protection systems.

Features

• FluidLoc Cable Protection: Special internal sealing ensures oil or other liquids do not leak out of the machine along the cable interior.
• Fully Threaded Body: Standard 3/8-24 UNF-2A threads run the full 7.7-inch case length with 0.0-inch unthreaded length to fit specific well or bearing casing configurations.
• Miniature ClickLoc Coaxial Connector: Heavy-duty gold-plated ClickLoc connector provides a reliable connection without requiring specialist tools.
• 1.5-Meter Length: Built with an integrated 1.5-meter (4.9-foot) high-temperature coaxial cable.
• Hazardous Area Approvals: Designated with the -05 approval option, meeting CSA, ATEX, and IECEx requirements.
• Robust Chemical and Physical Resistance: PolyPhenylene Sulfide (PPS) probe tip and stainless steel body offer excellent durability against corrosive industrial chemicals and mechanical stresses.

Applications

• Steam and gas turbine shaft vibration and axial displacement monitoring.
• Rotor displacement and wear monitoring in high-pressure gas compressors.
• Industrial pump shaft motion tracking and bearing degradation protection.
• Permanent monitoring of critical rotating machinery in power generation, petrochemical plants, and oil extraction facilities.

Ordering Information

The Bently Nevada 330101-00-77-15-12-05 represents a highly specific, order-to-build configuration of the 3300 XL 8 mm proximity probe series. The detailed breakdown of this orderable SKU code is as follows:

Technical Specifications

Installation Guidelines

• Thread Engagement: Ensure thread engagement does not exceed 0.563 inches (1.5 times the nominal thread diameter) to prevent binding or thread damage.
• Probe Gap Calibration: Mount with appropriate probe gap voltage as specified by the system configuration (typically -10 VDC bias for mid-range calibration).
• Fluid Intrusion Prevention: While the FluidLoc cable prevents internal leakage, use a thread sealant or O-ring on the case mounting to prevent outer process leaks.
• Cable Routing: Ensure minimum bend radius requirements are met, and route cables through dedicated conduit to avoid mechanical damage or electromagnetic interference.
• Connector Security: Finger-tighten ClickLoc coaxial connectors until they click. No special installation tools are needed. Do not over-torque using wrenches or pliers unless joining non-XL connectors.

Compliance and Certifications

• Agency Approvals (-05 Option): Evaluated and certified for hazardous environments under CSA, ATEX, and IECEx directives.
• Ex Classifications: Class I, Zone 0, 1, or 2, Group A, B, C, D (where applicable under intrinsic safety rules).
• RoHS: Compliant with electrical equipment hazardous substance restrictions.
