Bently Nevada 330103-10-15-10-02-05 3300 XL 8 mm Proximity Probe

Description

Option 10 (100 mm unthreaded length) and Option 15 (150 mm overall case length) specify this 3300 XL 8 mm proximity probe configuration — 330103-10-15-10-02-05. This metric-threaded, non-armored probe is manufactured by Bently Nevada and features an M10 x 1 thread layout. It is equipped with a 1.0 m total cable length (Option 10) terminated in a standard miniature coaxial ClickLoc connector (Option 02) and comes certified with hazardous area agency approvals (Option 05).

In contrast to standard 3/8-24 UNF threaded variants (such as the 330101 series) or armored metric configurations (such as the 330104 series), the 330103 series provides unarmored, threaded metric mounting for installations requiring an M10 x 1 thread pitch. The lack of mechanical armor reduces the outer diameter of the lead cable to 3.68 mm, facilitating simplified routing through standard conduits and tight bends inside machinery housings. This probe operates as a non-contacting transducer, generating an eddy-current field to measure dynamic shaft vibration, axial position, and speed relative to a target surface.

Features

• M10 x 1 metric thread configuration without protective stainless steel armor.
• 100 mm unthreaded length (Option A: 10) provides clear mounting offset.
• 150 mm overall case length (Option B: 15) allows deep reach into machine housings.
• 1.0 meter total lead length (Option C: 10) for direct connection to extension cables.
• Miniature coaxial ClickLoc connector (Option D: 02) with a gold-plated termination interface.
• Agency Approval Option 05 offers CSA, ATEX, and IECEx approvals for hazardous areas.
• Hermetically sealed tip constructed of polyphenylene sulfide (PPS) high-performance plastic.

Applications

• Radial shaft vibration measurements on fluid-film bearing machines.
• Thrust/axial rotor position monitoring on high-speed industrial compressors, turbines, and pumps.
• Eccentricity and phase reference (Keyphasor) monitoring.
• Hazardous area machinery protection environments requiring intrinsic safety certifications.

Installation Guidelines

• Do not exceed the maximum thread engagement length of 15 mm to prevent thread binding or internal case damage.
• Ensure a minimum target clearance of 40 mm around the 8 mm probe tip from adjacent structural metals to avoid side-view calibration offsets.
• Hand-tighten the miniature coaxial ClickLoc connector until an audible "click" is felt; do not use pliers on the gold connector sleeves unless explicitly required by system tooling.
• Observe minimum bend radius of 25.4 mm (1.0 in) for standard coaxial cables during routing.

Compliance and Certifications

• CSA Class I, Division 1, Groups A, B, C, and D
• ATEX Zone 0/1, Ex ia IIC T1...T5 Ga/Gb
• IECEx intrinsic safety approvals
• CE Compliant
