Bently Nevada 330901-00-40-10-02-00 3300 NSv Proximity Probe

Description

Option 00 (0.0 in unthreaded length), Option 40 (4.0 in overall case length), Option 10 (1.0 m total length), and Option 02 (standard ClickLoc coaxial connector) define the specific physical configuration of this 3300 NSv proximity probe, part number 330901-00-40-10-02-00.

This unarmored probe configuration is designed with a standard 1/4-28 UNF-2A thread, distinguishing it from armored versions (such as the 330902) or alternative 3/8-24 UNF thread variants (such as the 330908). It is calibrated to pair with the 3300 XL NSv Proximitor Sensor (330980) and 3300 NSv Extension Cable (330930) to form a complete 5-meter or 7-meter transducer system, used for non-contact displacement monitoring in confined locations where target area geometry is limited.

Features

• 1/4-28 UNF-2A thread configuration without stainless steel armor for direct standard mounting.
• Option 00 unthreaded length specifies a fully threaded 0.0 in (0 mm) case body.
• Option 40 case length provides a total case length of 4.0 in (102 mm).
• Option 10 total length delivers a 1.0 meter (39 in) FEP-insulated coaxial cable.
• Option 02 connector type provides a miniature coaxial ClickLoc connector on standard cable without a connector protector.
• Option 00 agency approval indicates that additional hazardous area certifications are not required for this unit.
• Polyphenylene sulfide (PPS) probe tip and AISI 304 stainless steel case body for durability in industrial process environments.

Applications

• Shaft radial vibration and axial position measurements in small-bore rotating machinery.
• Non-contact displacement monitoring in aeroderivative gas turbines.
• Integrity monitoring on high-speed pumps, compressors, and equipment with limited target geometry or tight installation clearance.

Installation Guidelines

• When drilling and tapping a mounting hole for a 1/4-28 probe, a #3 or larger tap drill is recommended.
• Ensure the maximum length of thread engagement does not exceed 0.375 inches (9.5 mm) to avoid binding during installation.
• Maintain a minimum separation of transducer tips of at least 25 mm (1.0 in) for axial measurements or 23 mm (0.9 in) for radial vibration measurements to prevent cross-talk.
• Hand-tighten the coaxial ClickLoc connector, then tighten finger-tight. The maximum recommended connector torque is 0.56 N-m (5 in-lb).
• Protect probe-to-extension cable connections with connector protectors or self-fusing silicone tape to prevent liquid ingress.
