Bently Nevada 330904-00-25-50-02-00 3300 XL NSv Proximity Probe

Description

330904-00-25-50-02-00: 3300 XL NSv proximity probe, M8x1 thread with stainless steel armor, 0.0 in unthreaded length (Option 00), 2.5 in case length (Option 25), and 5.0 m total length (Option 50). This probe is a critical component of the Bently Nevada 3300 XL NSv transducer system, specifically used for measuring shaft vibration and axial position in machinery where standard 3300 XL probes are not suitable due to target size or clearance limitations.

The system utilizes a 75 ohm coaxial cable path, which is defined by the Option 02 configuration (Miniature coaxial ClickLoc connector, standard cable). This specific unit is designed for use in environments where agency approvals are not required (Option 00). The 3300 XL NSv system is optimized for small-bore machinery and high-speed equipment where the target geometry requires a smaller probe tip and reduced linear range compared to conventional 8 mm proximity transducer systems.

Features

• M8x1 thread with stainless steel armor for mechanical protection in industrial environments
• Option 00 unthreaded length: 0.0 in (fully threaded design)
• Option 25 case length: 2.5 in
• Option 50 total system length: 5.0 m
• Option 02 connector type: Miniature coaxial ClickLoc connector, standard cable
• Option 00 agency approval: Not required
• 1.5 mm linear range for high-precision displacement measurement
• Compatible with 330980 Proximitor Sensor and 330930 extension cable

Applications

The 3300 XL NSv proximity transducer system is used for monitoring vibration and position on:

• Small-bore rotating machinery
• High-speed equipment with limited target area
• Aeroderivative gas turbines
• Centrifugal pumps and compressors where clearance is tight
• Rotating equipment requiring non-contact displacement measurement

Installation Guidelines

Ensure the probe is installed using the supplied lock nut. The recommended gap setting is 1.0 mm for optimal linear performance. When routing the cable, avoid sharp bends that exceed the minimum bend radius. Ensure all connectors are kept clean and free from moisture; use connector protectors if the application environment warrants additional environmental isolation. Probes must be grounded according to local safety standards, typically through the mounting bracket or specified grounding paths.

Compliance and Certifications

This configuration (Option 00) does not require specific hazardous area approvals. For hazardous area applications, ensure the correct approval option code is selected according to the site requirements and Bently Nevada documentation.
