SKU: 330703-000-080-10-02-00
Bently Nevada 330703-000-080-10-02-00 3300 XL 11mm Proximity Probe
The Bently Nevada 330703-000-080-10-02-00 is a 3300 XL 11mm proximity probe with an 8.0-inch case and 1.0-meter cable. It provides an extended 4.0 mm linear range for non-contact vibration monitoring in large-scale turbines and compressors.
Extended Range Monitoring for Critical Machinery Protection
The Bently Nevada 330703-000-080-10-02-00 drives high-performance machinery oversight by delivering an extended linear range compared to standard 8mm sensors. This 3300 XL 11mm series eddy current probe monitors shaft vibration and position without physical contact, ensuring zero mechanical wear. The 11mm tip provides a larger linear range of 4.0 mm (160 mils), making it the ideal solution for applications with higher expected displacement or where larger shaft diameters require a wider sensing field. By delivering this critical raw data to the 3500 Monitoring System, the probe enables automated machinery protection and advanced rotor dynamics diagnostics.

Operational Reliability and Asset Health
The 330703-000-080-10-02-00 maximizes machinery uptime by maintaining measurement stability in extreme industrial environments. The 8.0-inch case length allows the probe to reach through deep bearing housings or thick machine casings. The probe tip utilizes a rugged polyphenylene sulfide (PPS) construction that resists chemical corrosion and moisture ingress. By adhering to API 670 standards, this 11mm probe ensures precise monitoring for:
- Axial thrust position in large steam turbines and compressors
- Radial vibration in heavy-duty fluid-film bearing machines
- Differential expansion measurements in power generation assets
- Shaft eccentricity and thermal growth diagnostics during startup
Installation and System Integration
Maintenance technicians utilize the 1/2-20 UNF threads to secure the 330703-000-080-10-02-00, typically gapping it at the center of its 160-mil range for optimal linearity. To complete a standard 5.0-meter or 9.0-meter electrical loop, pair this 1.0-meter probe lead with a 3300 XL 11mm extension cable (4.0m or 8.0m). The gold-plated ClickLoc connector with an integrated protector (02 option) seals the connection against lubricating oils and environmental debris. This robust electrical path ensures that the 3500 rack receives a clean, noise-free data stream for reliable machinery protection and early fault detection.
