Bently Nevada 330902-00-95-02-00 3300 XL NSv Proximity Probe

Description

The 330902-00-95-02-00 is a 3300 XL NSv proximity probe configuration designed for applications where standard Bently Nevada 3300 XL 8 mm probes cannot be used due to space constraints. This specific variant features a 1/4-28 UNF thread with stainless steel armor for increased durability. The configuration includes a 9.5-inch case length (Option 95) and a fully threaded body (Option 00) for versatile mounting in confined spaces common in small-bore machinery and high-speed equipment. This probe is a primary component of the 3300 XL NSv Proximity Transducer System, which is engineered to measure radial vibration, axial (thrust) position, tachometer, and Keyphasor signals. The system is specifically optimized for small target applications, such as shafts smaller than 51 mm (2 in) or flat targets smaller than 15 mm (0.6 in), providing superior performance in reduced side-view environments. The probe uses a 75-ohm coaxial cable and a ClickLoc connector to ensure a secure, robust connection.

Features

• 1/4-28 UNF thread with stainless steel armor (Model 330902)
• Option 00: 0.0 in unthreaded length (fully threaded body)
• Option 95: 9.5 in total case length
• Option 02: Miniature coaxial ClickLoc connector with standard cable
• Option 00: Agency approval not required
• Provides non-contact, eddy-current displacement measurement for small target geometry
• Compatible with 3300 XL NSv Proximitor Sensor and 3300 NSv extension cables

Applications

• Radial vibration and position measurement on small-bore machinery
• Axial (thrust) position on restricted targets
• Aeroderivative turbines and process gas compressors
• High-speed equipment with tight installation requirements
• Replacement for 3300 RAM or 3000-series 190 transducer systems

Installation Guidelines

• Always install connector protectors on probe-to-extension cable connections to prevent liquid ingress.
• Ensure the probe is gapped according to the 3300 XL NSv Proximitor Sensor system manual.
• Maintain at least 0.7 inch difference between unthreaded length and case length during installation.
• Verify thread engagement; do not exceed probe thread engagement limits to avoid binding.
• Avoid exposing the probe tip to temperatures below -34 degC for sustained periods to maintain pressure seal integrity.
