Product Overview
The Bently Nevada 330905-00-16-05-02-CN is a 3300 NSv proximity probe engineered for reliable vibration and position measurement in demanding industrial environments. This model features an M10X1 thread, a 160 mm overall case length, and a 0.5 meter (20 inch) total length with a miniature coaxial ClickLoc connector and standard cable. As part of the 3300 NSv series, this probe delivers enhanced chemical resistance compared to earlier 3300 RAM probes, making it ideal for process compressor applications. The 330905-00-16-05-02-CN is supplied new and original in factory packing, backed by a 12-month warranty.
Key Features & Benefits
-
Enhanced Chemical Resistance: The NSv probe withstands harsher media than the 3300 RAM, expanding its use in process compressors.
-
Superior Side-View Characteristics: Provides more accurate gapping than the 3000-series 190 probe at the same distance from the target.
-
Interchangeable: Mechanically and electrically compatible with previous 3300 RAM probes and extension cables.
-
Robust Construction: Polyphenylene sulfide (PPS) probe tip and AISI 304 stainless steel case ensure durability.
-
Wide Temperature Range: Operates from -52°C to +177°C (-62°F to +351°F) for extreme environments.

Applications
The 330905-00-16-05-02-CN excels in radial vibration and axial position monitoring of rotating machinery. Typical applications include:
-
Process Compressors: The enhanced chemical resistance allows reliable operation where aggressive media are present.
-
Turbomachinery: Monitor shaft vibration and thrust position in turbines and generators.
-
Pumps and Fans: Detect early signs of bearing wear or misalignment.
Installation & Setup
For optimal performance, follow these guidelines:
- Mount the probe with the recommended torque (finger tight, up to 0.56 N·m). Over-tightening can damage the threads.
- Maintain the recommended gap setting of 1.0 mm (40 mils) to operate within the linear range.
- Use a flat target of at least 13 mm (0.5 in) diameter for accurate readings.
- Keep field wiring between the proximitor and monitor within 305 meters (1000 feet) to avoid signal rolloff.
- Respect the minimum bend radius of 25.4 mm (1.0 in) for the probe cable to prevent damage.
Maintenance & Reliability
The 330905-00-16-05-02-CN requires minimal routine maintenance. Periodically inspect the probe tip for contamination or damage, and verify that the cable is not bent beyond its minimum radius. The PPS tip and stainless steel case resist corrosion, extending service life in harsh environments. Because the probe is not pressure tested before shipment, consider a custom pressure test if your application involves differential pressure sealing.
Compatibility & Integration
This probe is designed to work with Bently Nevada 3300 XL NSv Proximitor Sensors and is mechanically and electrically interchangeable with previous 3300 RAM systems. It uses a miniature coaxial ClickLoc connector, ensuring a secure and reliable connection. The 330905-00-16-05-02-CN integrates seamlessly into existing Bently Nevada monitoring systems.
Selection Guide & Purchasing Advice
Before ordering, verify the thread type (M10X1), unthreaded length (00 mm), overall case length (160 mm), total length (0.5 m), and connector type (miniature coaxial ClickLoc) match your application requirements. Confirm that your monitor system supports the 3300 NSv series.
