Bently Nevada 330101-00-12-10-12-CN 3300 XL 8 mm Proximity Probe

Description

The Bently Nevada 330101-00-12-10-12-CN is a specialized non-contact proximity probe within the 3300 XL 8 mm Proximity Transducer System, engineered for precise industrial machinery vibration and shaft position monitoring. This configuration is explicitly designed for harsh operating environments, featuring a rugged, non-armored 3/8-24 UNF threaded body that resists mechanical stress in permanent installations. Unlike standard standard-cable models, this variant is equipped with a high-integrity FluidLoc cable, which prevents machine oil, cooling liquids, and process fluids from leaking or migrating through the interior of the coaxial cable braid to the outside of the machine casing. It features a compact 1.2-inch case length with 0.0 inches of unthreaded length, maximizing thread contact for shallow or standard mounting ports. Certified with the -CN regional suffix, this model is pre-packaged with Chinese hazardous area approvals, providing certified NEPSI and CCC safety markings for installations in highly regulated petrochemical, manufacturing, and power generation environments across mainland China.

Features

• FluidLoc Fluid Sealing: Incorporates a specialized FluidLoc cable option that prevents process oil and other industrial liquids from migrating through the internal copper braid of the coaxial cable.
• TipLoc Outer Molding: Utilizes a patented TipLoc molding method that forms an exceptionally strong bond between the polyphenylene sulfide (PPS) probe tip and the stainless steel body.
• ClickLoc Connectors: Corrosion-resistant, gold-plated connectors click securely with finger-tight force to prevent loosening from high-vibration exposure.
• China Regional Certification: Pre-approved with the -CN China package, delivering required NEPSI and CCC markings for rapid local regulatory clearance.
• Standard Threading: Fully threaded 3/8-24 UNF non-armored body provides strong mechanical attachment without requiring external armor sleeves.

Applications

This 3300 XL 8 mm proximity probe is deployed in heavy-industry applications to monitor rotating machinery components. Typical industrial applications include:

• Steam turbine shaft radial vibration and axial displacement monitoring
• Gas turbine bearing casing displacement and rotor thrust tracking
• Petrochemical fluid-film bearing pump and compressor shaft protection
• Hydroelectric generator shaft alignment and speed measurement
• Keyphasor reference and timing measurements on industrial gearboxes

Installation Guidelines

To ensure high measurement accuracy and long-term mechanical reliability, follow these engineering practices:

• Probe Gap Setting: Mount the probe with an initial gap corresponding to -9 Vdc output (typically 1.27 mm or 50 mils) to align the target surface at the center of the probe's linear operating range.
• Thread Engagement Limits: Keep thread engagement within 0.563 inches (14.3 mm) for the 3/8-24 UNF thread structure to avoid binding or cross-threading inside the port.
• Cable Protection: Route the FluidLoc cable with a safe bend radius. Use protective conduit if routing near abrasive environments, ensuring the ClickLoc connectors are kept clean and free of metal filings.
• System Calibration: This 1.0-meter probe must be connected to a matching extension cable and calibrated 3300 XL Proximitor sensor. Do not mismatch system lengths, as standard systems are tuned for exactly 5.0 meters or 9.0 meters total length.

Compliance and Certifications

The 330101-00-12-10-12-CN configuration complies with the following safety and quality standards:

• NEPSI: Certified for intrinsic safety and explosion-proof requirements in hazardous areas within China.
• CCC: China Compulsory Certification compliant for electrical safety and industrial application standards.
• CE Mark: Compliant with European EMC standards without requiring specialized shielded conduit.
