Bently Nevada 330102-00-20-30-12-CN 3300 XL 8 mm Proximity Probe

Description

The 330102-00-20-30-12-CN is an armored 3300 XL 8 mm proximity probe designed for reliable non-contact eddy-current displacement measurement in critical rotating machinery applications. This specific configuration features a 3/8-24 UNF thread, 0.0 in unthreaded length (Option 00), a 2.0 in case length (Option 20), and a 3.0 m total system length (Option 30). It utilizes a FluidLoc cable (Option 12) with a miniature coaxial ClickLoc connector to prevent oil migration, and includes the -CN suffix, signifying the China hazardous area approval package (NEPSI/CCC) for regulated environments.

This probe operates as a primary component in the Bently Nevada 3300 XL 8 mm transducer system, working in conjunction with a matching 3300 XL Proximitor sensor and extension cable. The inclusion of the protective armor (330102 series) provides mechanical reinforcement, making this probe suitable for industrial environments where abrasion or accidental impact to the cable is a concern. The FluidLoc cable construction is specifically intended to mitigate the risk of fluid leakage through the cable jacket, commonly required in lubricated machine housing applications.

Features

• Armored Housing: Integral stainless steel armor for enhanced mechanical protection and cable durability.
• FluidLoc Cable: Designed to prevent oil and liquid migration through the cable assembly, ensuring long-term seal integrity.
• ClickLoc Connector: Miniature coaxial connector system provides secure, reliable connection with standard 3300 XL cabling.
• Thread Configuration: 3/8-24 UNF-2A threading for standard installation in 8 mm probe holders.
• Hazardous Area Approval: Includes -CN suffix for China hazardous area compliance (NEPSI and CCC certification).
• System Compatibility: Designed for use with 3300 XL 8 mm Proximitor sensors and extension cables.

Applications

• Turbine and compressor shaft radial vibration monitoring
• Axial position (thrust) measurements
• Rotor speed and phase reference monitoring
• Critical rotating machinery in power generation, petrochemical, and oil and gas processing
• Installations requiring fluid ingress protection and cable armor protection

Installation Guidelines

Ensure the probe is installed with adequate clearance in the mounting bracket to prevent binding. Bently Nevada recommends limiting thread engagement to 1.5 times the nominal thread diameter. For armored cables, handle the probe with care to avoid kinking the armor, which can damage the internal coaxial cable. The connector must be kept clean and dry; hand-tighten the ClickLoc connectors until the gold locking mechanism clicks. In hazardous areas, verify installation against the local safety drawing and the -CN certification requirements.

Compliance and Certifications

• China Hazardous Area Approval: NEPSI, CCC (via -CN suffix)
• CE compliant
• RoHS compliant
