Bently Nevada 330104-00-07-10-01-CN Proximity Probe – 3300 XL 8mm Series
When a critical rotating machine loses its vibration monitoring capability, the consequences are immediate and severe: undetected shaft displacement, catastrophic bearing failure, unplanned downtime, and in worst cases, complete turbomachinery destruction. The Bently Nevada 330104-00-07-10-01-CN proximity probe is the front-line sensor that prevents this scenario — continuously measuring radial shaft vibration, axial position, and differential expansion with micron-level precision, 24 hours a day, 365 days a year.
Within the 3300 XL 8mm proximity probe series — Bently Nevada’s most widely deployed eddy-current sensing platform — the 330104-00-07-10-01-CN occupies a well-defined technical niche: a 7-metre (22.9 ft) armored extension cable configuration with CN-standard connector termination, designed for installations where the monitor rack is located at a distance from the machine casing. This part number is specified on tens of thousands of turbines, compressors, pumps, and gearboxes across global petrochemical, power generation, and heavy-industry facilities, making it one of the most sourced replacement probes in the industrial automation aftermarket.

Frequently Asked Questions
Q: Is the 330104-00-07-10-01-CN a new or refurbished part?
A: We supply both new (OEM) and certified-surplus units depending on availability. The condition is clearly stated in our quotation. All surplus units pass our QA inspection process.
Q: Can I use this probe with a 3300/16 monitor?
A: Yes. The 330104-00-07-10-01-CN is compatible with all standard 3300 XL series monitors when paired with the correct 3300 XL 8mm Proximitor driver. Verify your driver part number before ordering.
Q: What does the “-CN” suffix mean in the part number?
A: The “-CN” suffix designates the connector type — a standard Bently Nevada coaxial connector used on the majority of 3300 XL installations. It is not a country-of-origin designation.
Q: What is the lead time for this part?
A: Lead time varies by stock availability. In-stock units typically ship within 3–5 business days. For out-of-stock items, lead time is quoted individually — typically 2–6 weeks depending on sourcing channel.
Q: Do you provide export documentation for international shipments?
A: Yes. We provide commercial invoice, packing list, certificate of conformance, and can assist with any additional documentation required by your country’s import authority.
Q: What is the difference between 330104-00-07-10-01-CN and 330104-00-07-10-02-CN?
A: The last digit typically designates a minor configuration variant (e.g., connector orientation or cable jacket material). Please confirm your exact OEM part number from the machine documentation before placing an order.
