Bently Nevada 330709-000-080-10-02-00 11mm Proximity Probe

Product Overview

The Bently Nevada 330709-000-080-10-02-00 is a high-precision 11mm Proximity Probe from the 3300 XL series. This eddy current sensor is designed for non-contacting vibration and position measurements in critical rotating machinery. With its 11mm diameter, it is ideal for applications requiring a larger linear range than the standard 8mm probes, making it suitable for monitoring larger shaft diameters or systems with significant thermal expansion. This probe is supplied as 100% brand new, original factory stock, ensuring reliable data acquisition for your machinery protection systems.

Technical Specifications

Engineering Advantages

• Extended Linear Range:
  The 11mm tip diameter offers a 4.0 mm (160 mil) linear range—double that of the standard 8mm probes—allowing for precise measurement of large axial movements or thrust positions, particularly useful in thrust bearing monitoring or large turbine casing applications.

• High-Temperature Stability:
  Constructed with advanced polyphenylene sulfide (PPS) and stainless steel, the probe ensures accurate measurement even in harsh industrial environments with fluctuating temperatures, maintaining high performance over time.

• ClickLoc™ Connector Integrity:
  The gold-plated brass ClickLoc™ connectors provide a secure, moisture-resistant connection, and are designed to prevent accidental loosening due to machinery vibration, ensuring reliable sensor operation.

• Interchangeability:
  As part of the 3300 XL series, the probe is fully compatible with 3300 XL 11mm Proximitor® Sensors and extension cables, making spare parts management easy and cost-efficient.

FAQs

• What is the primary application for the 11mm probe versus the 8mm?
  The 11mm probe is ideal when a wider linear range is needed or when the target surface is not perfectly flat. It is commonly used for thrust bearing monitoring and to measure the thermal expansion of large turbine casings.

• Can I use this 8.0m probe with a 1.0m extension cable?
  No, proximity systems are tuned to specific total electrical lengths, usually 5.0m or 9.0m. This 8.0m probe is intended to be paired with a 1.0m extension cable, making the total system length 9.0 meters.

• What happens if the probe tip is scratched?
  Minor surface scratches on the PPS tip usually do not affect the eddy current field. However, any damage to the internal coil or metal casing requires immediate replacement to avoid signal drift.

• Is a specific Proximitor® required for this probe?
  Yes, the 330709-000-080-10-02-00 probe must be used with a 3300 XL 11mm Proximitor® Sensor. Using an 8mm Proximitor® will result in incorrect scale factors and inaccurate vibration readings.
