Bently Nevada 330709-000-070-10-02-00 3300 XL 11mm Proximity Probe

Product Overview

The Bently Nevada 330709-000-070-10-02-00 is a heavy-duty 3300 XL 11mm proximity probe designed for critical machinery protection in high-performance applications. This eddy-current sensor features an 11mm tip diameter, offering a significantly larger linear range compared to standard 8mm probes. It is the preferred choice for monitoring axial thrust position and radial vibration on large-scale turbomachinery such as steam turbines, high-capacity compressors, and industrial pumps, where thermal expansion requires a wider measurement window for accurate data collection.

Technical Specifications (Model Breakdown)

Engineering Advantages

• Extended Measurement Range: The 11mm system offers a 4.0 mm (160 mil) linear range, which is roughly double the range of the 8mm system. This is particularly crucial for axial position monitoring, where large machines exhibit high "float" or significant thermal growth during startup, making it essential to have a wider measurement window for accurate readings.

• Precision Metric Housing: The M16 x 1.5 threaded body is made of corrosion-resistant AISI 304 stainless steel, offering a robust mechanical interface for metric-standard machine casings. This feature ensures that the probe can be securely mounted in environments using metric threads without the need for adapters.

• ClickLoc Connector Security: The probe is equipped with gold-plated brass ClickLoc connectors that provide a moisture-resistant, vibration-proof electrical bond. The locking mechanism ensures the connection remains intact under the high-frequency vibration common in industrial machinery, guaranteeing stable performance over time.

• TipLoc Molding Technology: The Polyphenylene Sulfide (PPS) sensing head is chemically bonded to the probe body using the patented TipLoc method. This ensures that the probe tip remains intact and functional even under high pressure or fluid exposure, making it suitable for harsh industrial environments.

FAQs

What is the standard output scale factor for this 11mm probe?
When used with a matching 3300 XL 11mm Proximitor, the system provides an Average Scale Factor (ASF) of 3.94 V/mm (100 mV/mil), ensuring accurate vibration and position measurements.

Can this probe be used with an 8.0-meter extension cable?
Yes. Since this is a 1.0-meter probe, it is designed to be paired with an 8.0-meter extension cable to create a 9.0-meter total system length. Alternatively, a 4.0-meter extension can be used for a 5.0-meter system, depending on your application needs.

Is this a genuine, brand new Bently Nevada product?
We supply this probe in 100% brand new, original condition. Each unit is shipped in original factory packaging with a full serial number traceability and a factory calibration datasheet, ensuring the authenticity and quality of the product.

Why use M16 threads instead of the standard 1/2-20 threads?
The M16 x 1.5 thread option is specifically designed for international and European equipment manufacturers who use metric standards for sensor mounting ports. This ensures a direct fit without the need for adapters, making it ideal for global deployments.
