Bently Nevada 330171-12-41-10-02-05 3300 5 mm Proximity Probes

Bently Nevada 330171-12-41-10-02-05 Proximity Probe The Bently Nevada 330171-12-41-10-02-05, also cataloged as the 330171 proximity probe, operates as a dedicated hardware component for static and dynamic shaft displacement measurement within 3300 5 mm probe systems. Part Number Breakdown Model (330171): 3300 5 mm proximity probe Unthreaded Length (12): 1.2 inches unthreaded portion Overall Case Length (41): 4.1 inches case length Total Cable Length (10): 1.0 meter (3.3 feet) cable length Connector Option (02): Miniature coaxial ClickLoc connector with standard cable Agency Approval (05): Multiple hazardous area certifications Hardware Specifications Parameter Specification Model 330171-12-41-10-02-05 Brand Bently Nevada Origin USA Weight Not specified Dimensions Tip diameter 5 mm; case length 4.1 in; cable length 1.0 m Operating Temp Not specified Power Consumption Passive probe, excitation via proximitor Core Performance Eddy-current displacement measurement; TipLoc molding; miniature coaxial ClickLoc connector Eddy-Current Probe Scaling and Rotor Dynamics The probe translates magnetic field interactions into linear voltage outputs, enabling precise monitoring of shaft movement. Standard operating gap is validated at approximately -10 VDC (1.27 mm or 50 mils), ensuring balanced measurement in both directions. TipLoc molding secures the probe tip against mechanical stress, while coaxial shielding suppresses cross-talk between adjacent channels. Frequently Asked Questions Q: Can the 330171 probe be removed while the proximitor remains energized? A: Removal should only occur with the channel de-energized to prevent transient gap voltage excursions. Q: Does the 1.0 m cable length require recalibration of the proximitor? A: No. The cable length is factory-matched to standard proximitor modules. Q: How is mechanical durability ensured under vibration? A: TipLoc molding strengthens the bond between the probe tip and body, preventing displacement during rotor dynamic operation. Field Installation Guidelines Insert probe tip with full thread engagement to maintain mechanical stability. Ground shielding at the proximitor end only to avoid ground-loop formation. Route cables away from high-current conductors to minimize electromagnetic interference. Verify -10 VDC gap voltage reference during installation for accurate displacement scaling. Confirm hazardous area certifications before deployment in classified zones.
