Description
1. Product Title
Bently Nevada 330703-000-070-10-02-05 – 3300 XL 11mm Proximity Probe
2. Product Overview
The 330703-000-070-10-02-05 is a high-precision 11mm proximity sensor from the Bently Nevada 3300 XL series. This transducer is specifically engineered for non-contacting displacement and vibration measurements where a larger linear range is required than what standard 8mm probes can provide. It operates on the eddy current principle, converting the distance between the probe tip and a rotating shaft into an electrical signal.
This specific configuration of the 330703-000-070-10-02-05 is designed for rugged industrial environments, solving the problem of monitoring large-scale rotating equipment such as steam turbines and heavy-duty compressors. With its 11mm tip, it offers an extended linear range, making it the ideal choice for applications involving significant axial thermal expansion or where a larger gap between the sensor and the target is mechanically necessary.

4. Key Features & Benefits
- Extended Linear Range: Unlike standard 8mm probes, the <span style=”color: blue;”>330703-000-070-10-02-05</span> provides a 160-mil linear range, allowing for more movement of the target shaft without losing signal accuracy.
- Corrosion-Resistant Armor: The integrated stainless steel flexible armor protects the coaxial cable from physical damage, chemical exposure, and abrasion common in industrial machine trains.
- Enhanced Scale Factor Stability: Designed to work with the 3300 XL 11mm Proximitor, this probe maintains a consistent scale factor (typically 100 mV/mil) even under varying temperature conditions.
5. Application Scenarios
- Large Steam Turbine Thrust: Monitoring the axial position of turbine rotors where thermal growth requires a wider measurement window than standard probes allow.
- High-Power Centrifugal Pumps: Capturing radial vibration data in large-bore bearings where a more robust sensor tip is preferred for long-term stability.
- Hydroelectric Generator Monitoring: Ideal for measuring shaft runout and structural vibration in large vertical or horizontal hydro turbines.
6. Frequently Asked Questions (FAQ)
- Q: What is the primary function of the <span style=”color: blue;”>330703-000-070-10-02-05</span>?
- A: It is an 11mm proximity sensor used to measure vibration and displacement in large rotating machinery with an extended linear range.
- Q: Is <span style=”color: blue;”>330703-000-070-10-02-05</span> compatible with 8mm systems?
- A: No. This 11mm probe must be paired with a 3300 XL 11mm Proximitor and the correct 11mm extension cable to ensure accurate calibration and a 100 mV/mil output.
