Description

The Bently Nevada 330104-00-12-10-01-00 is an armored, metric-threaded 3300 XL 8 mm proximity probe engineered for highly precise, non-contact machinery protection and shaft dynamic measurement. Part of the industry-standard 3300 XL Transducer System, this specific configuration features a robust integrated stainless steel armor sleeve over the coaxial cable to prevent mechanical damage, cutting, or crushing in harsh operating environments. It is configured with an M10 x 1 metric thread, featuring a 120 mm fully threaded case (zero unthreaded length) and a total probe length of 1.0 meter (3.3 feet).

This model is terminated with a gold-plated miniature ClickLoc coaxial connector and includes a factory-installed connector protector (Option 01). The connector protector is vital for shielding the coaxial junction from oil, moisture, dust, and physical contamination. This SKU is supplied under Agency Approval Option 00, meaning it does not carry hazardous area certifications. This makes it an ideal, cost-effective solution for general-purpose industrial locations that do not require specialized explosion-proof or intrinsically safe markings.

When deployed within a complete machinery monitoring layout, the probe works in combination with a 3300 XL Proximitor Sensor and an extension cable to transmit reliable voltage signals proportional to the static and dynamic distance between the probe tip and the observed rotating shaft surface.

Features

• Rugged Stainless Steel Armor: Factory-installed flexible steel armor provides excellent mechanical protection against harsh physical impacts and abrasions.
• Fully Threaded Metric Case: Features an M10 x 1 metric thread, 120 mm case length, and 0 mm of unthreaded length, allowing maximum adjustment depth during installation.
• Connector Protector Installed: Built-in fluorosilicone connector protector seals the ClickLoc connection to block fluid contamination and maintain signal integrity.
• ClickLoc Coaxial Connection: Gold-plated click-type connector provides a secure, vibration-resistant electrical path with quick-disconnect capability.
• General-Purpose Configuration: Standard non-certified design (Option 00) optimized for clean, safe-area installations where expensive hazardous certifications are unnecessary.

Applications

The Bently Nevada 330104-00-12-10-01-00 is widely used to monitor shaft behavior on high-speed rotating equipment across various industries, including power generation, petrochemicals, and heavy manufacturing. Key applications include:

• Radial Vibration Analysis: Tracking high-frequency shaft orbital motion and displacement in hydrodynamic bearings.
• Axial Thrust Position: Monitoring rotor axial movement to detect thrust bearing degradation and prevent internal turbine contact.
• Keyphaser and Speed Sensing: Providing phase reference and rotational speed measurements.
• Harsh Physical Environments: Ideal for gearboxes, compressor housings, and locations where cables are exposed to falling debris or physical interference.

Technical Specifications

Connections and Interfaces

The probe cable is terminated with a miniature gold-plated coaxial ClickLoc connector. This male connector interfaces directly with a 3300 XL gold-plated coaxial extension cable. The integrated connector protector must be slid over the connection point to lock the connection in place and provide an environmental seal against fluids and particulate contamination.

Installation Guidelines

• Gap Calibration: The recommended physical gap setting for radial vibration monitoring is 1.27 mm (50 mils), which yields an approximate electrical output of -9 Vdc when paired with a calibrated 3300 XL Proximitor.
• Thread Engagement: Keep thread engagement within the maximum limit of 15 mm for M10 x 1 threads to avoid binding or mechanical stress during installation.
• Bend Radius: Avoid bending the armored cable section beyond its minimum dynamic bend radius of 25 mm to preserve the inner coaxial conductor's structure.
• General Grounding: Ensure proper shield grounding by connecting the extension cable shield at the monitor rack terminal only, maintaining an isolated circuit at the probe head.

Compliance and Certifications

This product is manufactured under ISO 9001 quality systems. Since Option 00 (Agency Approval: Not required) is specified, this specific probe does not carry hazardous area certifications (such as ATEX, IECEx, or CSA Class I Div 1). It is fully approved for general-purpose, non-hazardous industrial environments. For installations inside explosive atmospheres, a sibling variant with the -05 approval option must be specified.
