Bently Nevada 330103-00-10-10-02-05 3300 XL 8 mm Proximity Probe

Description

A metric thread profile of M10 x 1 without armor (base model 330103) featuring 0 mm unthreaded length (Option 00) and a 100 mm overall case length (Option 10) defines the configuration of the Bently Nevada 330103-00-10-10-02-05 3300 XL 8 mm proximity probe.

This eddy-current non-contacting displacement probe is a critical sensor used in 3300 XL 8 mm monitoring chains to deliver precise shaft vibration and axial position measurements. It interfaces directly with a 3300 XL extension cable and a 3300 XL Proximitor sensor. Unlike other configurations with protective armor, this unarmored standard coaxial variant is designed for routing inside protected dry-conduit environments or internal machine housings where external mechanical abrasion is minimized. The probe system utilizes Option 02 (standard coaxial cable with a miniature ClickLoc connector) and Option 05 (CSA, ATEX, and IECEx approvals) to ensure high-accuracy performance and certified operations in hazardous environments.

Features

• M10 x 1 metric threaded probe body without armor provides standard mounting compatibility in metric installations.
• Option 00 specifies a 0 mm unthreaded length, allowing maximum thread engagement inside the bracket or machine housing.
• Option 10 specifies a 100 mm overall case length, providing sufficient depth for internal machine clearances.
• Option 10 specifies a 1.0 meter (3.3 feet) total cable length, suitable for short-reach local junctions or connection to extension cables.
• Option 02 provides a gold-plated coaxial ClickLoc connector with standard FEP jacket cable.
• Option 05 provides CSA, ATEX, and IECEx agency approvals for intrinsic safety and non-sparking installations.
• High-stability polyphenylene sulfide (PPS) probe tip ensures robust resistance against corrosive fluids and extreme temperature cycles.

Applications

• Radial shaft vibration and dynamic motion analysis in heavy-duty turbomachinery.
• Thrust position and rotor axial displacement tracking on industrial gas turbines, steam turbines, and centrifugal compressors.
• Machinery protection and condition-based monitoring systems in oil, gas, chemical processing, power plants, and maritime operations.
• Shaft positioning and bearing clearance monitoring in large-scale gearboxes, electric motors, and pumps.

Installation Guidelines

• Always observe the maximum thread engagement limit of 15 mm for the M10 x 1 thread to avoid binding or housing damage during mounting.
• Tighten the gold-plated ClickLoc connector finger-tight only. Do not use pliers on these standard gold connectors to avoid crushing or strip damage.
• For proper transducer sensitivity, verify the probe tip is gapped near the center of its linear range, typically 1.27 mm (50 mils) or roughly -10 Vdc bias output voltage.
• Ensure that probe cables are physically isolated and routed inside robust electrical conduit systems when run through turbulent or oil-rich environments.
• Avoid installing or operating the probe in environments below -34 degC to protect the Viton pressure seal from structural failure.
