Bently Nevada 3300 XL 11mm Probe | 330707-00-20-10-11-00

Product Overview

The Bently Nevada 330707-00-20-10-11-00 is a high-performance 3300 XL 11mm proximity probe engineered for critical vibration and position monitoring on large rotating machinery. This model features a 5/8-18 UNF thread and is optimized for applications requiring a larger linear range than standard 8mm probes. With a shipping weight of just 0.17 kg, this Made in U.S.A. sensor offers rugged durability and superior chemical resistance, ensuring reliable data acquisition in the most demanding industrial environments.

Technical Configuration

Advanced Cable Engineering

This configuration utilizes a 1.0-meter FluidLoc cable, which prevents oil and other process fluids from leaking through the cable interior to the connector end. It features a miniature coaxial ClickLoc connector with an integrated connector protector, ensuring a secure and contamination-free electrical path. The 75 Ω triaxial FEP-insulated cable maintains signal integrity while offering excellent resistance to industrial solvents.

Thermal and Pressure Resilience

Designed for extreme conditions, the probe tip is constructed from Polyphenylene Sulfide (PPS) and the case from AISI 304 Stainless Steel. It operates reliably in temperatures ranging from -52°C to +177°C. The internal Viton O-ring provides a robust seal against differential pressure between the probe tip and the case, making it suitable for high-pressure process environments.

Technical Specifications

Installation & Maintenance Guide

Install the 5/8-18 UNF probe case using a recommended torque of 15.2 N•m (133 in•lb). Do not exceed the maximum rated torque of 45.2 N•m to prevent case deformation. Ensure the minimum bend radius of 25.4 mm (1.0 in) is maintained for the triaxial cable during routing. Connectors should be tightened finger-tight; if using tools, do not exceed 0.565 N•m. Note that exposing the probe to temperatures below -34°C may affect the longevity of the pressure seal.

Engineering Advantages

The 3300 XL 11mm system provides a wider linear range than standard 8mm systems, making it the preferred choice for large shafts and axial displacement measurements. The FluidLoc cable technology protects the delicate Proximitor sensor from oil migration, while the AISI 304 Stainless Steel case offers long-term corrosion resistance in harsh industrial chemical zones.

Technical FAQs

Q1: What is the benefit of the FluidLoc cable option?
A1: FluidLoc prevents process fluids (like lube oil) from traveling through the inside of the cable, ensuring the dry-side connections and sensors remain clean and functional.

Q2: Is a Certificate of Origin (COO) available for this product?
A2: Yes, a Certificate of Origin can be provided upon request for this Made in U.S.A. component.

Q3: Does the 330707-00-20-10-11-00 require agency approvals?
A3: This specific configuration (option -00) is the standard version and does not include hazardous area agency approvals.
