330910-00-07-05-02-00 Bently Nevada 0.5m NSv Probe

Product Overview

The Bently Nevada 330910-00-07-05-02-00 is a precision 3300 NSv series proximity probe designed for tight-clearance machinery applications. Featuring an M10 x 1 metric thread and integrated stainless steel armor, this sensor provides high-accuracy vibration and position data. The NSv (Narrow Side View) technology is specifically optimized for small-bore applications and centrifugal process compressors where standard probes might face interference from adjacent metal surfaces. This model is also electrically interchangeable with legacy 3300 RAM proximity systems.

Technical Specifications

Mechanical Design & Material Advantages

1. Specialized Housing: This probe features a 70 mm case length with no unthreaded portion, allowing for maximum flexibility in thread engagement up to the full 70 mm if required by the mounting bracket. The robust 304 stainless steel construction ensures mechanical stability, contributing to a system weight between 14 and 150 grams.

2. Advanced Material Durability: The probe tip uses PPS (Polyphenylene sulfide), which offers significantly better chemical resistance than the older 3300 RAM series. This makes it highly suitable for process compressors handling aggressive gases. An internal Viton O-ring provides a reliable pressure seal between the tip and case.

3. Narrow Side View (NSv) Performance: The NSv design optimizes the magnetic field to look primarily forward, which is essential when gapping probes near adjacent metal. This results in superior side-view characteristics compared to 3000-series sensors, ensuring that machine components do not skew your vibration readings.

Installation Guidelines

Gap Setting: The recommended gap for the 3300 NSv is 1.0 mm (40 mils). The linear range is approximately -1 to -13 Vdc. For accurate results on small shafts, ensure the target diameter is at least 13 mm (0.5 in).

Torque Limits: For the M10x1 case, the recommended installation torque is 11.3 N•m (100 in•lb). Do not exceed the maximum rated torque of 33.9 N•m to prevent deformation of the sensor housing.

Wiring and Signal: Use three-conductor shielded triad cable for field wiring. To maintain signal integrity up to 10 kHz, ensure the distance between the Proximitor Sensor and the monitor does not exceed 305 meters (1,000 feet).

Technical FAQs

Q: Can I use this probe with an existing 3300 RAM system?
A: Yes, the 3300 NSv is mechanically and electrically compatible with 3300 RAM probes and extension cables, allowing for a seamless drop-in replacement.

Q: What is the benefit of the stainless steel armor?
A: The armor provides critical protection for the coaxial cable against abrasion, physical impact, and sharp bends (maintain a 25.4 mm minimum bend radius) in harsh machinery environments.

Q: Is this probe rated for high-pressure environments?
A: It is designed to seal differential pressure via a Viton O-ring. However, if your specific application involves extreme pressure, contact technical support for additional seal testing verification.
