Product Overview
The Bently Nevada 330904-08-15-05-11-00 is a 3300 NSv proximity probe designed for reliable vibration and position measurement in critical rotating machinery. This industrial automation module features an M8X1 threaded case with armor, an 80 mm unthreaded length, a 150 mm overall case length, and a 0.5 meter total length. It includes a miniature coaxial ClickLoc connector with connector protector and FluidLoc cable, ensuring secure and stable connections in demanding environments.
This probe is mechanically and electrically interchangeable with Bently Nevada's previous 3300 RAM series, offering increased chemical resistance for process compressor applications. Its superior side-view characteristics make it ideal for precise gap measurements.

Key Performance Characteristics
The 330904-08-15-05-11-00 delivers a linear range of 1.5 mm (60 mils) with a recommended gap setting of 1.0 mm (40 mils). Its incremental scale factor of 7.87 V/mm ensures accurate displacement measurement. The probe's frequency response extends to 10 kHz, making it suitable for monitoring high-speed machinery.
With a deviation from best fit straight line of less than ±0.06 mm, this probe provides precise and repeatable readings. The PPS tip and stainless steel case offer durability in harsh industrial environments.
Applications
This proximity probe is widely used in:
- Process compressors where chemical resistance is critical.
- Turbomachinery vibration monitoring systems.
- Axial position measurement on rotating shafts.
- Industrial machinery health monitoring.
Its compatibility with Bently Nevada's 3300 XL NSv Proximitor Sensor ensures seamless integration into existing monitoring systems.
Installation & Setup
When installing the 330904-08-15-05-11-00, follow these guidelines:
- Apply finger-tight torque; do not exceed 0.56 N•m (5 in•lb).
- Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable.
- Ensure the target is flat and at least 8.9 mm (0.35 in) in diameter.
- For axial position measurements on smaller shafts, adjust gap to minimize scale factor changes.
Maintenance & Reliability
Regular inspection of the probe tip and cable is recommended. The Viton O-ring provides a differential pressure seal, but probes are not pressure tested before shipment. For applications requiring pressure testing, contact the custom design department. The probe's operating temperature range of -52°C to +177°C ensures reliable performance in extreme conditions.
Compatibility & Integration
The 330904-08-15-05-11-00 is compatible with Bently Nevada's 3300 XL NSv Proximitor Sensor and monitors. Field wiring can be up to 305 meters (1,000 feet) using three-conductor shielded triad cable. The probe's ClickLoc connector ensures a secure, quick connection.
Selection Guide
When selecting a replacement probe, verify the thread type (M8X1), unthreaded length (80 mm), overall case length (150 mm), and total cable length (0.5 m). Ensure the connector type matches your existing system. For expert advice and genuine parts, consider PLC Source PRO as your reliable supplier.
