Bently Nevada 330101-00-64-10-12-05 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-64-10-12-05 is a high-performance 8 mm proximity probe designed for non-contact machinery protection within the 3300 XL 8 mm Proximity Transducer System. This specific configuration is engineered with a fully threaded 6.4-inch stainless steel case, an unthreaded length of 0.0 inches, and a 1.0-meter total system length. It is equipped with a specialized FluidLoc cable terminated with a miniature coaxial ClickLoc connector. The probe is certified for hazardous areas with CSA, ATEX, and IECEx approvals.

Utilizing the eddy-current operating principle, this probe provides precise shaft vibration and displacement measurements in critical rotating machinery, such as gas turbines, steam turbines, high-pressure compressors, and pumps. The patented FluidLoc cable option prevents oil and other process liquids from migrating along the interior of the cable, ensuring superior environmental containment and safety. By interfacing directly with a 3300 XL Proximitor sensor, this probe delivers stable, linear output signals over a broad temperature range and integrates seamlessly with industrial DCS or Bently Nevada 3500 monitoring systems.

Features

• 8 mm tip diameter optimized for non-contacting eddy-current displacement measurements.
• FluidLoc cable construction blocks oil and process fluids from leaking through the cable interior.
• Fully threaded 6.4-inch stainless steel case with lock nuts for rigid mounting in bearing housings.
• Miniature coaxial ClickLoc connector features corrosion-resistant, gold-plated contacts with finger-tight security.
• Patented TipLoc molding method guarantees an exceptionally robust physical bond between the probe tip and body.

Applications

• Continuous shaft vibration and position monitoring in steam and gas turbines.
• Rotor axial displacement and thrust position measurement in industrial compressors and pumps.
• Thrust bearing wear and thermal expansion monitoring on heavy rotating equipment.
• Permanent installation on bearing housings in power generation, chemical, and oil and gas facilities.

Installation Guidelines

Probes must be mounted with the correct physical gap as specified by the system calibration, typically 1.27 mm (50 mils) when using standard AISI 4140 steel targets. Maintain appropriate probe thread engagement limits to prevent binding during installation. Ensure the coaxial cables are routed through protective conduits with proper grounding and shielding practices to prevent high-frequency interference. For explosive and hazardous atmospheres, verify compliance with entity parameters and install the device in accordance with Bently Nevada drawing 141092.

Compliance and Certifications

This proximity probe holds international certificates for hazardous area applications under ATEX, IECEx, and CSA standards. It is certified for intrinsic safety (ia) and non-sparking/increased safety (nA, ec) installations. The standard 3300 XL Proximitor system satisfies European CE requirements for electromagnetic immunity without requiring specialized metallic conduits.
