Product Overview

The Bently Nevada 330901-00-41-05-02-CN is a ruggedized 11mm proximity probe engineered for high-precision machinery protection. Utilizing advanced eddy current technology, this probe measures shaft vibration and axial position without physical contact. It serves as a primary sensing element for the 3300 XL series, delivering critical data to 3500 Series monitoring systems. This specific configuration features a 4.0-meter integrated cable and M14 x 1.5 metric threading, making it a vital component for monitoring high-speed rotating assets such as steam turbines, centrifugal compressors, and large-scale industrial pumps.

Technical Specifications

Engineering Advantages

The 330901-00-41-05-02-CN resolves complex measurement challenges in high-stakes rotating environments:

• Extended Linear Range: The 11mm tip diameter provides a wide 2.5 mm (100 mil) linear range. This increased span allows the probe to monitor large-scale displacement and shaft movement that smaller 5mm or 8mm probes cannot accurately capture.

• Extreme Thermal Stability: This probe operates reliably in temperatures reaching +180 °C. The specialized construction prevents signal drift, ensuring that vibration data remains accurate even when mounted in the hot sections of gas or steam turbines.

• EMI/RFI Immunity: The 3300 XL design incorporates advanced shielding within the integrated cable. This protects the low-voltage eddy current signal from industrial noise generated by nearby motors, drives, and power lines.

• Simplified Maintenance: The 0.5-meter sleeve length protects the cable-to-probe junction from mechanical stress during installation. This design extends the service life of the sensor in high-vibration applications.

FAQs

• Is this Bently Nevada 330901-00-41-05-02-CN unit brand new?

  Yes. We supply this probe in 100% Brand New and Original condition. Each unit includes the standard 1-year warranty and arrives in original factory packaging to ensure it meets all OEM calibration and sensitivity benchmarks.

• Can I use this 11mm probe with a standard 8mm Proximitor?

  No. You must pair the 330901 11mm probe with a dedicated 3300 XL 11mm Proximitor® Sensor. Using an 8mm Proximitor will result in incorrect scale factors and inaccurate vibration readings.

• What does the "-CN" suffix indicate?

  The -CN suffix denotes that this specific unit is manufactured and packaged for the China region. It maintains the exact same technical specifications, materials, and performance quality as standard Bently Nevada proximity probes used worldwide.

• What is the significance of the M14 x 1.5 thread?

  The M14 x 1.5 thread is a metric standard. Always verify your machine's mounting port thread before installation. If your housing uses imperial (English) threads, you will require the 1/2-20 variant (Model 330902) instead of this 330901 metric model.
