330905-00-25-05-01-CN Bently Nevada Space-Constrained Probe

Product Overview

The 330905-00-25-05-01-CN specializes in monitoring small rotating assets where standard probes cannot fit. The NSv design offers a narrower linear range but a significantly smaller tip diameter and side-view profile, making it the primary choice for centrifugal compressors and specialized pumps. We supply this unit as 100% Brand New in original factory packaging, ensuring full compliance with Bently Nevada’s stringent calibration standards for machinery protection.

Technical Specifications

Engineering Advantages

The 330905-00-25-05-01-CN addresses the specific challenges of high-density machinery monitoring:

• Optimized for Small Targets: Unlike standard 8mm probes, the NSv series functions perfectly on smaller shaft diameters and narrow target areas. This eliminates "side-view" interference from nearby machine components.

• Ruggedized Signal Path: The protected coaxial cable resists common industrial contaminants including synthetic lubricants and hydrocarbons found in chemical processing plants.

• Space-Saving Integration: The compact 1/4-28 UNF thread profile allows for installation in tight bearing housings where traditional vibration sensors cannot be maneuvered.

• ClickLoc™ Security: The gold-plated miniature connector utilizes a positive-locking mechanism. This prevents cable disconnection due to machine vibration and ensures a low-impedance signal path for noise-free data transmission.

FAQs

How does the NSv series differ from the standard 3300 XL 8mm probe?

The NSv series (Narrow Side View) features a smaller physical footprint and is specifically designed for small machinery or shafts with limited target space. While the 3300 XL has an 80-mil range, the NSv typically provides a 60-mil range with a much smaller tip diameter to avoid sensing the sides of a narrow counterbore.

Can I use this probe with a 3300 RAM system?

Yes. The 330905-00-25-05-01-CN maintains full backward compatibility with Bently Nevada 3300 RAM systems, allowing you to upgrade sensors without replacing your entire monitoring rack.

What is the significance of the "-CN" suffix?

The "-CN" suffix indicates that the probe meets specific Chinese regulatory and agency standards. It remains functionally identical to standard global models but carries the necessary documentation for use in projects requiring local compliance.

What extension cable should I use with a 0.5m probe?

To achieve a standard 5.0m system length, pair this 0.5m probe with a 4.5m 3300 NSv extension cable. For a 7.0m system, use a 6.5m extension cable. Always match the system length to the calibration of your NSv Proximitor sensor.
