Bently Nevada 330171-08-24-10-02-00 3300 5mm Proximity Probe

Description

Option 08 (0.8 in unthreaded length) and Option 24 (2.4 in overall case length) specify this non-armored 3300 5 mm proximity probe configuration — 330171-08-24-10-02-00.

This configuration is supplied with a 1.0 m (3.3 feet) integrated total cable length (Option 10) terminated with a gold-plated miniature coaxial ClickLoc connector on standard FEP-insulated coaxial cable (Option 02) without a separate connector protector. It does not carry hazardous area agency certifications (Option 00), rendering it suitable for standard safe-area industrial machinery layouts. Built with a reduced 5.2 mm (0.21 in) tip diameter, this probe fits into confined mechanical spaces where standard 8 mm probes cannot be deployed, such as narrow spaces between thrust bearing pads, while delivering identical electrical performance characteristics within compatible 3300 XL transducer systems.

Features

• Option 08 unthreaded case length of 0.8 inches for exact mechanical depth calibration.
• Option 24 overall case length of 2.4 inches with 1/4-28 UNF thread profile.
• Option 10 integrated total cable length of 1.0 meter (3.3 feet).
• Option 02 miniature coaxial ClickLoc connector with robust gold-plated brass contacts.
• Non-armored standard coaxial cable with chemical-resistant FEP insulation.
• Reduced 5.2 mm (0.21 in) probe tip diameter for installation in constrained mechanical envelopes.
• Standard non-approval configuration (Option 00) for general industrial safe-area usage.

Applications

• Radial shaft vibration and axial shaft position monitoring on high-speed rotating machinery.
• Thrust bearing clearances and position measurements within tight internal clearances.
• Rotational speed and Keyphasor phase reference measurements on fluid-film bearing machines.

Installation Guidelines

• Unthreaded Length Clearance: Maintain correct offsets; the unthreaded case length must be at least 0.8 inches less than the overall case length to prevent thread binding or inadequate engagement.
• Connector Hand-Tightening: Standard ClickLoc connectors must be finger-tightened until a tactile "click" is felt. Do not apply wrenches or special tools to the miniature coaxial coupling.
• Environmental Protection: Since this SKU has standard cable without a connector protector (Option 02), we recommend utilizing silicone tape or acquiring separate connector protectors if the probe-to-cable junction is exposed to machine fluids or ambient moisture.
• Lock Nut Torque: Secure the 1/4-28 UNF thread with the supplied lock nut (provided with standard 13 mm or 7/16 in hexagonal dimensions) to prevent loosening under high vibration.
• Tap Drill Selection: Use a #3 or larger tap drill size when preparing mounting holes for 1/4-28 UNF-2A probes to prevent thread binding.

Compliance and Certifications

• FCC: Complies with Part 15 of FCC Rules.
• EMC: Meets standards EN 61000-6-2, EN 61000-6-4, and EMC Directive 2014/30/EU.
• RoHS: Compliant with Directive 2011/65/EU.
• Maritime: Certified under ABS 2009 Steel Vessels Rules (1-1-4/7.7, 4-8-3/1.11.1, and 4-9-7/13).
