Bently Nevada 330103-01-04-10-02-05 3300 XL 8 mm Proximity Probe

Description

Option 01 (10 mm unthreaded length) and Option 04 (40 mm overall case length) specify the physical configuration of this M10 x 1 metric threaded proximity probe — 330103-01-04-10-02-05. This unarmored probe operates on eddy-current principles to measure static and dynamic distance, capturing shaft vibration and axial position feedback. Equipped with a 1.0-meter (3.3 feet) standard cable (Option 10) terminated in a miniature coaxial ClickLoc connector (Option 02), this specific model matches with 3300 XL Proximitor sensors and extension cables without requiring manual bench calibration.

This configuration incorporates Option 05 agency approvals, providing compliance with CSA, ATEX, and IECEx hazardous area standards. Choosing the unarmored version with metric M10 x 1 casing provides a compact mechanical envelope suitable for industrial machinery installations where external conduit armor is not required. The patented TipLoc molding provides a bond between the 8.0 mm probe tip and the stainless steel threaded body.

Features

• Option 01 specifies a 10 mm unthreaded body length.
• Option 04 provides a 40 mm overall threaded case length with an M10 x 1 thread pattern.
• Option 10 supplies a 1.0-meter (3.3 feet) standard coaxial cable.
• Option 02 provides a miniature ClickLoc coaxial connector without a connector protector.
• Option 05 provides CSA, ATEX, and IECEx hazard zone approvals.
• TipLoc molding securement resists probe tip delamination.
• CableLoc connection design withstands up to 330 N (75 lbf) pull strength.
• Complete interchangeability across 3300 XL series probes, cables, and Proximitor sensors.

Applications

The probe is used for heavy-industry machinery protection and condition monitoring. Typical scenarios include:

• Shaft vibration and axial position measurement on fluid-film bearing machines.
• Keyphasor reference and speed measurements on steam turbines, gas turbines, and compressors.
• Casing expansion and radial vibration monitoring on industrial pumps and generators.

Installation Guidelines

Ensure standard engineering practices are followed during installation:

• Thread Engagement Limit: The maximum thread engagement length is 15 mm for M10 x 1 casings. Do not exceed this limit to avoid binding during installation.
• Cable Bend Radius: Do not bend the coaxial cable to a radius of less than 25.4 mm (1.0 in) to preserve signal shielding.
• Torque Limits: Do not exceed the recommended maximum tightening torque for standard metric threads (typically 12 N-m or 106 in-lb for M10 threads).
• Gap Setting: Set target gap to approximately 1.27 mm (50 mils) to achieve a nominal -9 Vdc output voltage at the Proximitor sensor output terminals.

Compliance and Certifications

• Option 05 provides approvals for hazardous locations.
• CSA Class I Division 1, Groups A, B, C, and D.
• ATEX Zone 0 and Zone 1 explosion protection standards.
• IECEx certification for global intrinsically safe compliance.
• CE Mark compliant.
• RoHS compliant.
