Bently Nevada 330101-00-75-05-01-05 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-75-05-01-05 is a high-reliability 8 mm proximity probe engineered for non-contact machinery vibration and shaft position measurements. Designed to integrate seamlessly within the Bently Nevada 3300 XL monitoring system, this unarmored proximity probe operates on the eddy-current principle to supply real-time, micro-inch displacement data to your machinery protection system. Unlike standard sibling configurations, this specific variant features a unique combination of a 0.0-inch unthreaded length (00) and a 7.5-inch overall case length (75), making it highly suitable for deep casing insertions where threaded adjustment is required along the entire body length.

This SKU is supplied with a 0.5-meter (1.6 feet) standard coaxial cable (05) and comes pre-terminated with a miniature ClickLoc coaxial connector that includes an integrated connector protector (01). This protector is vital for maintaining connection integrity and safeguarding against oil, water, or chemical ingress inside bearing housings. Representing the -05 agency approval path, this probe is certified for industrial hazardous atmospheres under ATEX, IECEx, and CSA standards, providing a robust sensing element for critical rotating assets.

Features

• Non-contact eddy-current sensing for reliable, long-term vibration and shaft position tracking.
• Standard 3/8-24 UNF threaded body style without armor, optimized for compact bearing housings.
• Custom case configuration featuring a 0.0-inch unthreaded body length combined with a 7.5-inch total case length.
• Integrated ClickLoc miniature coaxial connector with an included connector protector to prevent liquid contamination.
• Fully compatible with the 3300 XL Proximitor sensor and standard extension cables for calibrated system response.
• Rugged tip construction designed to endure aggressive industrial environments and exposure to lubrication oils.

Applications

• Steam and gas turbine shaft vibration and axial displacement monitoring.
• Compressor and high-pressure pump rotor position tracking.
• Permanent mounting in machinery casings and bearing housings for predictive maintenance.
• TSI (Turbine Supervisory Instrumentation) chains on high-speed critical machinery.

Installation Guidelines

• Verify and adjust the probe mechanical gap setting in accordance with your system calibration sheets (typically targeting a nominal 1.27 mm or 50 mils gap).
• Keep cable bends above the minimum specified bending radius to ensure long-term mechanical reliability.
• Ensure the pre-installed ClickLoc connector protector is fully closed and secured to prevent lubricant ingress inside the housing.
• Isolate and route the field cabling inside dedicated conduit channels with proper grounding practices to block electrical interference.

Compliance and Certifications

• CSA Approved for hazardous and explosive environments.
• ATEX Certified for safe zone operations.
• IECEx Approved for global intrinsic safety and flameproof installations.
