Bently Nevada 330908-00-15-05-02-00 3300 NSv Proximity Probe

Description

An unthreaded length of 0.0 inches (Option 00) and an overall case length of 1.5 inches (Option 15) define this 330908-00-15-05-02-00 3300 NSv proximity probe configuration, which is equipped with a 0.5-meter (20-inch) total length cable (Option 05).

This unarmored probe features standard 3/8-24 UNF threads and a gold-plated miniature coaxial ClickLoc connector (Option 02) without an integrated connector protector. Supplying this probe configuration with the Option 00 approval selection means no agency certifications are required for the installation. The 3300 XL NSv proximity transducer system is specialized for machinery with highly restricted physical installations or exceptionally small target areas, such as centrifugal air compressors or refrigeration units. It is optimized to perform non-contact shaft displacement, radial vibration, and axial position monitoring on fluid-film bearing machines.

Features

• Option 00 unthreaded design provides a fully threaded housing for fine-depth calibration.
• Option 15 case length of 1.5 inches accommodates restricted envelopes in compressor enclosures.
• Option 05 short-length cable of 0.5 meters (20 inches) reduces slack and simplifies internal cable routing.
• Option 02 ClickLoc miniature coaxial connection delivers a secure and robust electrical interface.
• Unarmored FEP-insulated coaxial cable design reduces weight and overall routing cross-section.
• Polyphenylene sulfide (PPS) tip construction coupled with an AISI 304 stainless steel case offers high resistance to process fluids.

Applications

• Radial vibration and radial position measurements on compact compressors
• Axial (thrust) position measurements on small-diameter machinery shafts
• Tachometer, speed, and phase reference (Keyphasor) signal generation
• Aeroderivative gas turbines and compact industrial machinery diagnostics

Installation Guidelines

To establish safe and precise vibration monitoring, the following engineering installation guidelines must be followed:

• Torque Limits: For 3/8-24 UNF steel probe cases, the recommended installation torque is 11.3 N m (100 in-lb). Do not exceed the maximum rated torque of 33.9 N m (300 in-lb) to avoid damage to the threads or internal seals.
• Cable Protection: Keep the minimum cable bend radius above 25.4 mm (1.0 in). Avoid routing cables near high-voltage AC lines to prevent magnetic or electrostatic coupling.
• Connector Integrity: Coaxial ClickLoc connectors should be joined finger-tight. The use of connector protectors or silicone self-fusing tape is recommended in wet or oily environments to prevent signal degradation.
• Target Geometry: Maintain proper clearances around the probe tip. To minimize side-view interference (cross-talk), ensure that the counterbore diameter surrounding the probe tip is at least 13 mm (0.5 in).

Compliance and Certifications

The 3300 XL NSv Transducer System complies with the following standards and directives when integrated with compatible system components:

• EMC Directive 2014/30/EU (EN 61000-6-2, EN 61000-6-4)
• RoHS Directive 2011/65/EU
• Functional Safety: SIL 2 (HFT=0), SIL 3 (HFT=1) certified
