Bently Nevada 330104-03-12-05-02-05 3300 XL 8 mm Proximity Probe

Description

Option 03 (30 mm unthreaded length), Option 12 (120 mm overall case length), and Option 05 (0.5 meter total length) specify this metric 3300 XL 8 mm proximity probe configuration — 330104-03-12-05-02-05. This eddy-current proximity probe features M10 x 1 threads, integrated stainless steel armor (Model 330104), and a ClickLoc coaxial connector.

This configuration differs from non-armored siblings (such as the 330103) by incorporating a protective stainless steel armor sleeve over the coaxial cable to resist abrasion, cutting, and mechanical wear. In contrast to standard 1.0-meter or 5.0-meter configurations, the 0.5-meter total length matches shorter routing clearances or direct connection points, and Option 02 provides a standard ClickLoc miniature coaxial connector without an outer connector protector sleeve.

Features

• Model 330104 specifies M10 x 1 metric thread with integrated stainless steel armor.
• Option 03 provides a 30 mm unthreaded length for specialized mechanical mounting depth.
• Option 12 dictates a 120 mm overall case length with 90 mm of active thread engagement.
• Option 05 configures a 0.5 meter (1.6 feet) total probe cable length.
• Option 02 supplies a miniature coaxial ClickLoc connector with standard FEP coaxial cable.
• Option 05 grants CSA, ATEX, and IECEx certifications for hazardous area installations.

Applications

Typically used for radial vibration, axial position, and speed measurements on rotating machinery. Suitable applications include power generation, petrochemical, and oil and gas industries, specifically on turbine shafts, compressors, gearboxes, and large industrial pumps requiring armored mechanical cabling.

Installation Guidelines

Maintain proper target alignment and probe-to-target gap (nominally 1.27 mm or 50 mils). Ensure the maximum thread engagement does not exceed 15 mm for the M10 x 1 threads to avoid binding during installation. Connectors must be kept clean and dry, tightened only finger-tight. Observe a minimum bend radius of 25 mm for the armored section of the coaxial cable during routing.
