Bently Nevada 330101-00-85-05-01-05 3300 XL 8 mm Proximity Probe

Description

Option 00 (0.0 in unthreaded length, fully threaded) and Option 85 (8.5 in overall case length) specify this 3300 XL 8 mm proximity probe configuration — 330101-00-85-05-01-05. This non-contact eddy-current displacement probe without armor has a total cable length of 0.5 meters (Option 05) and is equipped with a miniature coaxial ClickLoc connector with a connector protector (Option 01). It is approved for hazardous areas under Option 05 (CSA, ATEX, IECEx Approvals).

This 3300 XL 8 mm proximity probe pairs with a 3300 XL Proximitor sensor and an extension cable to form a complete 3300 XL transducer system. Operating on the eddy-current principle, the system measures static and dynamic distance between the probe tip and the target. This makes the transducer system ideal for critical rotating machinery protection applications, including shaft vibration and axial position monitoring on steam turbines, gas turbines, compressors, and pump rotors.

Features

• Fully threaded 3/8-24 UNF steel probe body without armor (Option 330101)
• 0.0 inches of unthreaded length (Option 00) for complete thread engagement
• 8.5 inches overall case length (Option 85) for deep mounting configurations
• 0.5 meter (1.6 feet) total probe cable length (Option 05)
• Miniature coaxial ClickLoc connector with integrated connector protector (Option 01)
• CSA, ATEX, and IECEx agency approvals for hazardous locations (Option 05)
• High-durability polyphenylene sulfide (PPS) probe tip with stainless steel body (AISI 303 or 304)
• Moisture-resistant construction with Viton O-ring seal to prevent process media leakage

Applications

• Turbine shaft vibration and axial position monitoring
• Thrust bearing wear and radial clearance measurement
• Compressor and pump rotor displacement tracking
• Permanent mounting on bearing housings and machine casings
• Machinery protection systems for power generation, petrochemical, and oil and gas operations

Technical Specifications

Installation Guidelines

• Mount the probe with the appropriate probe gap (nominally 1.27 mm or 50 mils) corresponding to system calibration.
• Observe the minimum permissible cable bend radius of 25.4 mm (1.0 in) to prevent coaxial damage.
• Tighten the probe case to bearing housings up to the recommended torque of 7.5 N-m (66 in-lbf), not exceeding the maximum of 11.2 N-m (100 in-lbf).
• Route standard cable with proper shielding and grounding practices to minimize external electromagnetic interference.

Compliance and Certifications

• CSA, ATEX, and IECEx approvals for hazardous areas (Option 05)
• Suitable for intrinsically safe and non-incendive installations when wired in accordance with Bently Nevada control drawings
