Bently Nevada 330101-13-37-10-12-05 3300 XL 8 mm Proximity Probe

Description

A highly reliable non-contact sensor designed for critical machinery protection, the Bently Nevada 330101-13-37-10-12-05 is an eddy-current based 3300 XL 8 mm Proximity Probe. This specific configuration features a 1.3-inch unthreaded length and a 3.7-inch overall case length with 3/8-24 UNF threads, lacking mechanical armor for easy installation in protective conduits. Equipped with a patented FluidLoc coaxial cable and a standard miniature ClickLoc connector, it prevents process fluids or lubricating oil from leaking out of the machine casing through the cable's interior. As part of the 3300 XL monitoring chain, this probe is calibrated to work seamlessly with 3300 XL Proximitor sensors and standard extension cables to deliver precise, high-accuracy displacement and vibration measurements on high-speed rotating shafts.

Features

• Provides high-accuracy, non-contact shaft vibration and position measurements.
• Features an 8 mm tip diameter optimized for eddy-current displacement sensing.
• Equipped with a FluidLoc cable option (Code 12) that prevents oil migration through the cable core.
• Constructed with a rugged polyphenylene sulfide (PPS) tip and AISI 303/304 stainless steel case for demanding industrial environments.
• Certified for hazardous area installations with CSA, ATEX, and IECEx approvals.
• Designed for permanent mounting on bearing housings, casings, or machine structures.

Applications

• Steam and gas turbine shaft vibration monitoring.
• Centrifugal compressor and high-pressure pump rotor displacement measurement.
• Critical rotating machinery protection in oil and gas, petrochemical, and power generation industries.
• Applications requiring oil-tight seal barriers where cables exit machine casings.

Installation Guidelines

• Mount the probe with the appropriate probe gap per system calibration, taking care to maintain the correct tip clearance from adjacent metal structures.
• Observe the minimum cable bend radius of 25.4 mm (1.0 inch) during routing to prevent attenuation or damage to the coaxial core.
• Ensure that the probe case torque does not exceed 11.2 N-m (100 in-lbf) for standard mounting to avoid stripping threads or damaging the internal assembly.
• Route the FluidLoc cable with proper shielding and industrial-grade grounding practices to shield against high-frequency electromagnetic interference.
• Connect the miniature ClickLoc connector finger-tight; do not use pliers unless interfacing with non-XL stainless steel connectors.

Compliance and Certifications

• Hazardous Area Approvals: ATEX, IECEx, and CSA certified for intrinsically safe (ia) and non-incendive (nA/ec) applications.
• Functional Safety: SIL 2 (HFT = 0) and SIL 3 (HFT = 1) certified for safety instrumented systems.
• Directives: European Community EMC Directive 2014/30/EU and RoHS Directive 2011/65/EU.
