Description

The Bently Nevada 330101-00-24-10-12-CN is an eddy-current-based 3300 XL 8 mm Proximity Probe engineered to provide precise, non-contact shaft vibration and displacement measurements in high-performance rotating machinery. Operating as a critical sensor within the 3300 XL monitoring chain, this probe detects dynamic distance changes between the probe tip and a rotating target (such as a turbine or pump shaft), converting physical displacement into high-fidelity electrical signals for analysis by a paired Proximitor sensor.

This specific configuration is uniquely optimized for environments demanding superior protection against fluid migration and regional safety compliance. Built with a 3/8-24 UNF threaded body, this model features a 2.4-inch case length with a 0.0-inch unthreaded section, allowing for direct-mount configuration in standard bearing housings. To safeguard terminal connections and prevent process oils or lubricating fluids from escaping the machine enclosure, this model is equipped with a specialty FluidLoc cable (Option 12). The FluidLoc design blocks liquids from migrating through the internal voids of the coaxial cable, providing a robust seal against pressure differentials. Additionally, the integrated -CN suffix guarantees full compliance with the China regional hazardous area approval package, including certified NEPSI and CCC safety markings for safe installation in localized regulated environments.

Features

• Highly durable polyphenylene sulfide (PPS) tip and AISI 303/304 stainless steel probe body built to withstand harsh machinery casing environments.
• Patented FluidLoc cable barrier prevents oil and other process liquids from leaking outwards through the interior of the cable.
• Corrosion-resistant, gold-plated coaxial ClickLoc connector provides secure, vibration-resistant coupling without requiring specialized tools.
• Fully compatible with Bently Nevada 3300 XL series Proximitor sensors and 3500 rack monitoring channels.
• China regional compliance package (-CN) guarantees quick regional approval and adherence to explosion-proof standards.

Applications

This proximity probe is widely deployed in heavy rotating machinery monitoring systems, including:

• Steam turbine and gas turbine shaft vibration and axial position monitoring.
• Compressor and high-pressure pump rotor displacement tracking.
• Gearbox shaft displacement and bearing clearance monitoring.
• Machine casing and bearing housing vibration protection in petrochemical, power generation, and water treatment plants.

Installation Guidelines

To ensure optimal measurement performance and longevity, observe the following installation criteria:

• Ensure proper probe gap settings are established using a static calibrator or voltmeter per system requirements before tightening the lock nuts.
• Adhere to the maximum rated probe case torque of 11.2 N-m (100 in-lbf) during installation to prevent damage to the threaded case.
• Route the FluidLoc cable carefully to respect the minimum bend radius of 25.4 mm (1.0 inch) and protect the connection from sharp physical edges.
• Connectors must be joined finger-tight; they will "click" when the locking mechanism is properly engaged.
• Ensure the probe assembly and shielding are grounded properly back to the monitoring rack system to prevent electrical noise interference.

Compliance and Certifications

This assembly is certified for use in industrial and hazardous environments with the following approvals:

• NEPSI: Explosion-proof and intrinsically safe approvals for China regional locations.
• CCC: China Compulsory Certification for industrial electrical safety.
• CE / RoHS: Compliant with European safety and environmental standards.
