330851-02-000-080-10-01-CN Bently Nevada High-Temp Armored Probe

Product Overview

The Bently Nevada 330851-02-000-080-10-01-CN is an ultra-rugged 3300 XL 25mm proximity probe designed for large-scale rotating machinery. Engineered for extreme environments, this armored sensor provides non-contact displacement measurements with a wide linear range. It is particularly suited for monitoring steam turbines and high-speed rail traction motors where high pressure, EMI interference, and thermal cycling are constant. The "CN" designation ensures compliance with specific national standards, making it ideal for regional power and infrastructure projects requiring high-precision vibration monitoring.

Technical Configuration

This complete model configuration is built for maximum physical and electrical protection in industrial settings:

• Full Model: 330851-02-000-080-10-01-CN
• 080 Case Code: 80mm stainless steel armored body, designed to withstand 15kN crushing force.
• Thread Type: M30x2 metric thread achieving high sealing torque without galling.
• Cable Protection: 304 SST armor providing IP69K sealing against high-pressure washdowns.
• Measurement Tech: 3300 XL 25mm eddy current technology for large-gap displacement.

Technical Specifications

Installation & Maintenance

When installing the 330851-02-000-080-10-01-CN, use a 68N•m sealing torque for the M30x2 threads to ensure a leak-proof fit. The armored cable allows for a 1,200N tensile stress during conduit pulling, significantly reducing the risk of internal wire damage. For Zone 0 installations, ensure the ambient temperature remains within the certified -55°C to +232°C range to maintain intrinsic safety. Regular inspections of the Viton® O-ring are recommended in high-pressure steam applications.

Engineering Advantages

The primary advantage of this armored configuration is its Extreme Environment Resilience. It survives 250°C steam bursts and 1,500-hour salt spray tests, making it the preferred choice for maritime and power substation applications. Its low EMI footprint ensures measurement accuracy near high-voltage equipment, while its dimensional compatibility allows for the direct upgrade of legacy 7200-series 25mm sensors without machining modifications.

Technical FAQs

Q1: What is the benefit of the SST-armored Case Code 080?
A1: It provides extreme crush resistance (up to 15kN), protecting the probe internals from physical deformation in high-pressure or heavy-debris environments.

Q2: Can this 25mm probe be used with an 8mm Proximitor?
A2: No. The 25mm system requires a specific 3300 XL 25mm Proximitor Sensor calibrated for the larger target diameter and linear range.

Q3: Does the "CN" suffix affect technical performance?
A3: No, it primarily indicates certification and documentation compliance for the Chinese market while maintaining identical high-performance specs to standard global models.
