Bently Nevada 330909-00-60-10-02-05 3300 NSv Proximity Probe

Description

Option 00 (0.0 in unthreaded length) and Option 60 (6.0 in overall case length) specify this stainless steel armored 3300 NSv proximity probe configuration — 330909-00-60-10-02-05.

Unlike unarmored versions such as the 330908, the 330909 design integrates protective stainless steel armor over the 1.0-meter coaxial cable to prevent abrasion and mechanical wear in challenging machinery environments. This configuration features a miniature coaxial ClickLoc connector (Option 02) with no connector protector and standard cable, and carries a multiple approvals agency package (Option 05) for installation in hazardous environments. This non-contact eddy-current displacement sensor is designed for tight clearances and reduced target areas where standard-sized probes cannot fit.

Features

• Option 00 unthreaded length provides a fully threaded probe casing for compact mounting.
• Option 60 provides a 6.0-inch overall case length constructed of robust AISI 304 stainless steel.
• Option 10 specifies a 1.0-meter total probe cable length.
• Option 02 includes a miniature coaxial ClickLoc connector on standard 75-ohm FEP-insulated cable.
• Integrated flexible AISI 302 stainless steel armor provides physical shielding for the cable.
• Option 05 agency approval package delivers ATEX, IECEx, and CSA certifications for hazardous zones.
• Polyphenylene sulfide (PPS) probe tip ensures excellent chemical resistance and durability.

Applications

Used in small-bore machinery, aeroderivative gas turbines, centrifugal compressors, pumps, and high-speed equipment with limited target geometries. This system is ideal for monitoring radial vibration, axial position, and speed in confined industrial spaces.

Installation Guidelines

• Maintain a minimum 9.5 mm probe-to-probe clearance to prevent electromagnetic cross-talk.
• Ensure the recommended minimum counterbore diameter of 13 mm (0.5 in) is applied.
• Torque the 3/8-24 thread casing up to a maximum rated torque of 33.9 N m (300 in-lb).
• Do not exceed the minimum cable bend radius of 25.4 mm (1.0 in).
• Ensure ClickLoc connectors are connected finger-tight during installation.
