Bently Nevada 330101-00-08-05-12-CN 3300 XL 8 mm Proximity Probe

Description

330101-00-08-05-12-CN: This 3300 XL 8 mm proximity probe configuration has a fully threaded 3/8-24 UNF body (Option 00) with a 0.8-inch overall case length (Option 08). The probe has a 0.5-meter total length (Option 05) and an option 12 FluidLoc coaxial cable with a miniature ClickLoc connector that blocks oil and process fluids from leaking through the inner cable core. This version carries the -CN suffix, which adds Chinese localized certifications including NEPSI and CCC.

The probe acts as a non-contact eddy-current sensor for shaft vibration and axial position measurement. It interfaces with a 3300 XL Proximitor sensor and extension cable in 3300 XL machinery protection loops. The unarmored design fits tight industrial casings where liquid containment along the signal path is mandatory.

Features

• Option 12 FluidLoc coaxial cable blocks machine oil and process fluids from migrating through the cable core.
• Option 00 unthreaded length of 0.0 inches means the probe case is fully threaded.
• Option 08 provides a compact 0.8-inch case length for restricted bearing enclosures.
• Option 05 0.5-meter total cable length matches standard 3300 XL monitoring system configurations.
• Viton O-ring pressure seal maintains differential pressure between the probe tip and case.
• Polyphenylene sulfide (PPS) tip material resists chemical degradation in harsh machine environments.
• Gold-plated brass and beryllium copper ClickLoc connectors maintain steady electrical continuity.

Applications

• Steam and gas turbine shaft vibration and axial displacement monitoring.
• Reciprocating compressor and pump rotor position tracking.
• Rotating machinery protection in environments where process fluid leakage through cabling is a hazard.
• Permanent installations on machine casings and bearing housings requiring NEPSI or CCC hazardous area approval.

Installation Guidelines

• Ensure the probe gap is set per the system calibration curve (typically 1.27 mm or 50 mils for a 3300 XL 8 mm system).
• Do not exceed the maximum case torque limit during installation. Recommended thread engagement matches standard engineering practices.
• Properly route the FluidLoc probe cable using standard shielding, grounding, and conduit practices to protect against EMI and physical wear.
• Avoid exposing the Viton O-ring seal to temperatures below -34 degC to preserve seal integrity.

Compliance and Certifications

• NEPSI: Certified for explosive gas and dust atmospheres in mainland China.
• CCC: China Compulsory Certificate for industrial safety and explosion protection.
