Bently Nevada 330103-00-12-10-01-00 3300 XL 8Mm Sensor

The Bently Nevada 330103-00-12-10-01-00 is a high-performance proximity sensor from the industry-standard 3300 XL 8mm series. This eddy current probe measures the dynamic and static distance between the sensor tip and a conductive target, such as a rotating shaft. By providing high-resolution displacement data, it enables the detection of mechanical issues like shaft vibration and axial position shifts. This specific model features a 3/8-24 UNF threaded body, which ensures a secure and standardized fit in most industrial machinery housings.

Design Features and Environmental Resilience

Bently Nevada builds this 8mm probe to survive the aggressive atmospheres found in power plants and refineries. The probe tip uses polyphenylene sulfide (PPS), which creates a hermetic seal against oil, water, and chemical penetration.¹ Furthermore, this model includes a 1.2-inch unthreaded length and a 1.0-meter integrated cable. The cable terminates with a gold-plated ClickLoc miniature coaxial connector. This connection type successfully resists mechanical vibration and environmental corrosion. Consequently, the sensor maintains signal stability even in high-temperature environments.

Industrial Applications and Integration

The 3300 XL 8mm system integrates seamlessly with Bently Nevada 3500 and 2300 machinery protection racks. It provides the essential data required for Turbine Supervisory Instrumentation (TSI). Because of its wide linear range and reliability, maintenance teams utilize this probe for:

• Radial vibration monitoring on fluid-film bearings
• Thrust (axial) position tracking in high-speed compressors
• Shaft eccentricity measurements for large electric motors
• Phase reference (Keyphasor) signal generation for speed measurements
• Critical asset protection in hydroelectric and steam power plants
