High-Precision 330905-00-13-10-02-CN Bently Nevada Vibration Probe

Product Overview

The Bently Nevada 330905-00-13-10-02-CN is a high-performance proximity probe from the 3300 NSv (Near Side view) family. This specific configuration features an M10x1 thread, a 130mm overall case length, and a 1.0-meter total length. Engineered for environments where narrow gaps and chemical exposure are prevalent, such as process compressors, the NSv series provides superior side-view characteristics to prevent signal interference from the surrounding machine housing. It is a robust, non-contacting solution for measuring shaft vibration and axial position in critical rotating machinery.

Technical Specifications

Core Technical Advantages

Enhanced Material Resilience

The probe tip is constructed from high-tensile Polyphenylene Sulfide (PPS), providing 500 MPa of strength and exceptional resistance to the corrosive gases and oils found in process compressor applications. This material science upgrade ensures the 330905 maintains structural integrity in extreme thermal conditions ranging from cryogenic lows to +177°C.

Advanced Dynamic Response

Engineered for high-fidelity data, the 3300 NSv system maintains 90% signal accuracy at 8kHz, even when running through up to 305 meters of field cabling. With 69.9 pF/m capacitance and a low-resistance center conductor, it minimizes signal attenuation and noise, allowing for the detection of minute, high-frequency vibration patterns.

Interchangeable Precision

This probe is 100% electromechanically compatible with legacy 3300 RAM systems. However, its "Near Side view" design offers superior alignment and reduced interference compared to the older 3000-series 190 probes when operating at the same 1.0mm (40 mil) gap setting, providing more reliable data in confined machinery internals.

Installation & Maintenance

• Tightening Specs: For the M10x1 housing, the recommended operational torque is 7.5 N•m. Do not exceed the maximum rating of 22.6 N•m to prevent damage to the 304 Stainless Steel threads.
• Cable Management: The 75Ω coaxial cable features a 25.4mm minimum bend radius. Avoid sharp kinks to maintain signal clarity across the 1.0-meter probe lead.
• Vibration Protection: The miniature coaxial ClickLoc connector is designed to remain secure under high-vibration loads, ensuring a continuous electrical path between the probe and Proximitor sensor.

Engineering Advantages

The Bently Nevada 330905-00-13-10-02-CN is optimized for long-term reliability. Its Viton O-ring provides a robust pressure seal between the tip and case, preventing process leaks. Weighing approximately 0.45 kg, this module is both durable and lightweight, making it easy to install in complex rack or enclosure setups while meeting specific regional -CN certifications for industrial compliance.

Technical FAQs

Q1: What is the benefit of the 130mm case length?
A1: The longer 130mm case allows the probe to be mounted through thicker machine housings or internal brackets while keeping the connector accessible for maintenance.

Q2: Can I use this probe without an extension cable?
A2: Typically, a total system length of 5.0 or 7.0 meters is required for calibration. A 1.0m probe must be paired with the appropriate extension cable to reach the required system electrical length.

Q3: How does the NSv series handle "side-view" interference?
A3: The NSv (Near Side view) design uses a smaller sensing field diameter, which prevents the probe from "seeing" the sides of a narrow mounting hole, resulting in a cleaner vibration signal.
