Bently Nevada 330102-05-30-50-02-05 3300 XL 8 mm Proximity Probe

Description

330102-05-30-50-02-05: 3300 XL 8 mm proximity probe, 3/8-24 UNF threaded body with stainless steel armor, Option 05 unthreaded length, Option 30 overall case length, Option 50 total system length, Option 02 miniature coaxial ClickLoc connector, and Option 05 hazardous area agency approvals.

This specific configuration includes a flexible stainless steel armor with an FEP outer jacket to protect the FEP-insulated coaxial cable from abrasion and physical damage in harsh operating environments. The 5.0 m total length of the probe is calibrated to function with a 5.0 m 3300 XL Proximitor sensor without the need for a separate extension cable, simplifying the measurement loop setup for specific machinery casings. The standard ClickLoc connector provides a secure coaxial connection without a connector protector.

Features

• Integrated stainless steel armor with FEP outer jacket protecting the probe lead from physical and abrasive damage.
• Calibrated 5.0 m total length (Option 50) designed for direct connection to a 5.0 m Proximitor sensor.
• 3/8-24 UNF threaded case with a 3.0 in case length and 0.5 in unthreaded length for precise mounting adjustments.
• Miniature ClickLoc coaxial connector (Option 02) providing a secure connection without a connector protector.
• Certified under CSA, ATEX, and IECEx (Option 05) for deployment in hazardous industrial areas.
• 8.0 mm probe tip made of rugged polyphenylene sulfide (PPS) for thermal stability and chemical resistance.

Applications

• Shaft vibration and axial position measurement on rotating machinery such as gas turbines, steam turbines, compressors, and pumps.
• Machinery protection systems where mechanical wear requires armored probe cabling.
• Hazardous area environments matching ATEX, IECEx, and CSA Class I, Division 1 and 2 specifications.
• Space-constrained configurations where a 5.0 m direct connection is required.

Technical Specifications

Installation Guidelines

• Grounding: Ensure the transducer system is properly grounded via the Proximitor sensor housing and that shielding is maintained through the extension cable.
• Minimum Bend Radius: The armored coaxial cable has a minimum bend radius of 25.4 mm (1.0 in). Avoid sharp bends or kinks during installation.
• Mounting Torque: Tighten the probe case to a maximum torque of 22.6 N-m (200 in-lbf). For standard forward-mount applications, do not exceed 7.5 N-m (66 in-lbf) on the first three threads.
• Probe Gap: Use the standard gap voltage of -10.0 Vdc (corresponding to approximately 1.27 mm / 50 mils) when calibration is done with a 3300 XL Proximitor sensor.
• Cable Protection: Run armored cabling through conduit or tray systems where exposed to heavy mechanical traffic or excessive fluids.
