Bently Nevada 3300 NSv Probe M10X1 - 330905-05-08-10-12-05

Product Overview

The 330905-05-08-10-12-05 is a premium 3300 NSv Proximity Probe engineered for industrial machinery where space is limited and high-accuracy vibration or position data is critical. This M10X1 threaded probe, weighing approximately 0.32 kg, features enhanced chemical resistance compared to legacy models, making it ideal for process compressor applications. Its superior side-view characteristics allow for precise gapping even in confined targets. Every unit arrives in original factory packing, backed by a 12-month warranty to ensure maximum reliability for your asset protection system.

Technical Configuration

Ordering Code Logic

This specific configuration includes a 50mm unthreaded length and an 80mm overall case length. The system utilizes a 1.0-meter total length cable equipped with a Miniature coaxial ClickLoc connector and FluidLoc technology to prevent oil migration. The Multiple Approvals option (-05) ensures global compliance for various industrial standards.

Advanced Material Science

The probe tip consists of high-grade Polyphenylene Sulfide (PPS), while the case utilizes AISI 304 Stainless Steel (SST). This combination provides a rugged interface capable of operating in extreme temperatures ranging from -52°C to +177°C. The FEP-insulated coaxial cable maintains signal integrity even in oily or chemically aggressive environments.

Technical Specifications

Installation & Maintenance Guide

Install the probe by tightening the M10X1 case to the recommended torque of 7.5 N•m (66 in•lb) for the first three threads. Ensure the center conductor dc resistance measures 4.2 ± 0.5 ohms for a 1.0m probe to verify electrical integrity. Maintain a minimum bend radius of 25.4 mm (1.0 in) for the coaxial cable to prevent signal degradation. When gapping against targets smaller than 13mm, reduce the gap setting slightly to maintain scale factor accuracy.

Engineering Advantages

The 3300 NSv series offers complete mechanical and electrical interchangeability with previous 3300 RAM systems, allowing for seamless upgrades. Its Viton O-ring seal provides a robust differential pressure barrier between the tip and case. The ClickLoc connector system ensures a secure, vibration-proof connection that is vital for continuous machinery monitoring in high-vibration environments.

Technical FAQs

Q1: Is the 330905-05-08-10-12-05 compatible with 3300 RAM cables?
A1: Yes, the NSv probe is mechanically and electrically interchangeable with the legacy 3300 RAM series components.

Q2: What is the benefit of the FluidLoc cable option?
A2: The FluidLoc cable prevents oil and other process fluids from leaking through the cable interior, protecting the Proximitor sensor environment.

Q3: Can this probe be used on very small shafts?
A3: While recommended for targets above 13mm, it performs better on small shafts than the 3000-series probes. Reducing the gap setting helps maintain the scale factor on smaller diameters.
