Product Overview
The Bently Nevada 330905-05-13-10-01-00 is a precision 3300 NSv proximity probe engineered for reliable vibration and position monitoring in critical rotating machinery. This Industrial Automation Module delivers accurate displacement measurements with a linear range of 1.5 mm (60 mils) and a recommended gap setting of 1.0 mm (40 mils). Its enhanced chemical resistance makes it ideal for process compressor applications where aggressive media are present.
This model, the 330905-05-13-10-01-00, features an M10X1 thread without armor, a 50 mm unthreaded length, a 130 mm overall case length, and a 1.0 meter (39 in) total length. It comes with a miniature coaxial ClickLoc connector and connector protector, with standard cable. The probe is mechanically and electrically interchangeable with Bently Nevada's previous 3300 RAM probe, simplifying upgrades.

Industry Applications
The 330905-05-13-10-01-00 excels in critical machinery monitoring, including:
-
Process Compressors: Its increased chemical resistance compared to the 3300 RAM probe allows reliable operation in harsh environments.
-
Turbomachinery: Provides precise shaft vibration and axial position measurements, enabling early fault detection.
-
Pumps and Fans: Monitors radial vibration to prevent bearing failures and unplanned downtime.
With its superior side-view characteristics, this probe ensures accurate gap readings even when mounted at a distance from the target, making it a versatile choice for retrofit and new installations.
Installation & Setup Guidance
Proper installation is critical for optimal performance. Follow these guidelines:
- Mount the probe with the recommended torque (finger tight) to avoid damaging the threads.
- Maintain a minimum bend radius of 25.4 mm (1.0 in) for the cable to prevent signal degradation.
- Set the initial gap to 1.0 mm (40 mils) from the target surface.
- Use shielded triad cable for field wiring, with a maximum length of 305 meters (1000 feet) to the Proximitor Sensor.
- Ensure the target surface meets the recommended minimum diameter of 13 mm (0.5 in) for accurate scale factor.
Maintenance & Reliability
Routine inspection of the probe tip and cable is recommended to ensure long-term accuracy. Check for physical damage, contamination, or chemical attack on the PPS tip. The stainless steel case offers excellent corrosion resistance, but verify the O-ring seal integrity in pressure applications. Periodic calibration checks against a known reference can confirm the scale factor remains within specification. These practices minimize downtime and extend service life, delivering a strong return on investment.
Compatibility & Integration
The 330905-05-13-10-01-00 is designed for use with Bently Nevada 3300 XL NSv Proximitor Sensors and monitoring systems. It is mechanically and electrically interchangeable with the previous 3300 RAM probe, allowing direct replacement in existing installations. The miniature coaxial ClickLoc connector ensures secure, repeatable connections. For seamless integration, verify that your monitor system supports the 7.87 V/mm (200 mV/mil) scale factor.
Selection Guide & Purchasing Advice
Before ordering, confirm the required unthreaded length, overall case length, total length, and connector type. This model includes a 1.0 m cable and ClickLoc connector with protector. Ensure that the thread size (M10X1) matches your mounting hole. For applications requiring pressure testing, contact the custom design department.
