Bently Nevada 330104-00-07-90-02-00 3300 XL 8 mm Proximity Probe

Description

The 330104-00-07-90-02-00 is an 8 mm proximity probe from the 3300 XL transducer system, configured with an M10 x 1 threaded case, integrated armor for mechanical protection, and a 9.0-meter total system length. This eddy-current displacement probe is designed for non-contact measurement of shaft vibration and axial position in critical rotating machinery, such as steam turbines, compressors, and pumps. This specific configuration features a 0 mm unthreaded length (Option 00), 70 mm case length (Option 07), and the standard Miniature ClickLoc coaxial connector (Option 02). As a component of the 3300 XL system, this probe provides an accurate voltage output proportional to the gap between the probe tip and the observed conductive surface. It is engineered for seamless compatibility with 3300 XL Proximitor sensors and extension cables, ensuring high signal integrity and system-wide performance in demanding industrial environments. The inclusion of armor (330104 series) provides additional durability in applications where the cable is exposed to abrasive or hazardous mechanical conditions.

Features

• M10 x 1 threaded probe body with armor for enhanced mechanical protection
• 9.0 meter system length for remote Proximitor sensor installation
• Miniature ClickLoc coaxial connector for secure, reliable signal termination
• Eddy-current technology for precise, non-contact measurement of radial vibration and axial displacement
• Industry-standard compatibility with 3300 XL series monitoring chains
• 0 mm unthreaded length and 70 mm case length configuration

Applications

• Radial vibration monitoring on large rotating machinery
• Axial (thrust) position measurement for rotor protection
• Steam and gas turbine monitoring
• Centrifugal and reciprocating compressor vibration analysis
• Hydroelectric generator shaft position monitoring
• High-abrasion environments requiring armored cable protection

Installation Guidelines

• Ensure the probe is gapped correctly according to the 3300 XL system manual (typically 1.27 mm using a feeler gauge).
• Use the appropriate Bently Nevada mounting brackets (e.g., aluminum or phenolic) to ensure structural stability and required electrical isolation.
• Avoid excessive thread engagement; limit torque to the values specified in the datasheet to prevent binding.
• Protect all connectors with connector protectors if the application involves exposure to fluids or abrasive dust.
• Ensure proper grounding of the Proximitor sensor housing to reduce electromagnetic interference (EMI).

Compliance and Certifications

• System certified for use in hazardous areas when installed per Bently Nevada drawing 141092 (intrinsic safety) or 140979 (non-incendive).
• Compliant with 3300 XL series electrical and mechanical performance standards.
