Product Overview
The Bently Nevada 330904-00-10-05-02-00 is a 3300 NSv proximity probe designed for reliable vibration and position monitoring in demanding industrial environments. This model features an M8X1 thread with armor, a 100 mm overall case length, and a 0.5 meter total length with a miniature coaxial ClickLoc connector. It is part of the 3300 NSv series, which offers enhanced chemical resistance compared to previous 3300 RAM probes, making it suitable for process compressor applications.
This Bently Nevada 330904-00-10-05-02-00 probe is mechanically and electrically interchangeable with earlier 3300 RAM probes, allowing for straightforward upgrades. The side-view characteristics are superior to the 3000-series 190 probe, providing more accurate gapping at the same distance from the target. With a linear range of 1.5 mm (60 mils) and an incremental scale factor of 7.87 V/mm (200 mV/mil), it delivers precise measurements for critical machinery protection.

Installation & Setup
Proper installation of the Bently Nevada 330904-00-10-05-02-00 ensures accurate readings. Follow these guidelines:
- Mount the probe with finger-tight torque; do not exceed 0.56 N•m (5 in•lb).
- Maintain the recommended gap of 1.0 mm (40 mils) from the target surface.
- Use the specified field wiring: three-conductor shielded triad cable, 0.2 to 1.5 mm² (16 to 24 AWG).
- Ensure the cable bend radius is at least 25.4 mm (1.0 in) to avoid damage.
- For axial position measurements on shafts smaller than 13 mm (0.5 in), adjust the gap to minimize scale factor changes.
Applications
The 330904-00-10-05-02-00 is ideal for vibration monitoring on rotating machinery such as compressors, turbines, and pumps. Its enhanced chemical resistance makes it particularly suited for process compressor applications where exposure to aggressive media is common. The probe’s robust design and wide operating temperature range (-52°C to +177°C) allow deployment in harsh environments, ensuring reliable operation in critical processes.
Maintenance & Reliability
Regular inspection of the probe and cable is recommended to maintain performance. Check for physical damage, especially at the bend radius, and verify that the connector is secure. The probe’s PPS tip and stainless steel case resist corrosion, but periodic cleaning may be necessary in dirty environments. The Viton O-ring provides a differential pressure seal; however, probes are not pressure tested before shipment. If pressure sealing is critical, contact the custom design department for testing.
Selection Guide
When selecting a replacement probe, verify the thread type (M8X1), overall case length, and total length to match your existing system. The 330904-00-10-05-02-00 is compatible with Bently Nevada 3300 XL NSv Proximitor Sensors and monitors. For expert assistance and genuine parts, consider PLC Source PRO as a reliable supplier.
