Bently Nevada 330104-00-09-15-01-00 3300 XL 8 mm Proximity Probe Metric

Introduction

Industrial rotating machinery has evolved from simple mechanical systems to complex, high-speed assets requiring continuous health monitoring. The Bently Nevada 330104-00-09-15-01-00 represents a key component in this evolution, offering precise proximity sensing for vibration and position measurement. As part of the 3300 XL series, this 8 mm probe delivers the accuracy and durability needed in demanding environments like power generation and oil and gas.

Technical Specifications Breakdown

The 330104-00-09-15-01-00 features a probe tip made of polyphenylene sulfide (PPS) and a case constructed from AISI 303 or 304 stainless steel, ensuring corrosion resistance and mechanical strength. Its M10x1 thread allows secure mounting, with a maximum thread engagement of 15 mm. The overall case length is 90 mm, and the total length is 1.5 meters (4.9 feet), using a miniature coaxial ClickLoc connector with connector protector and standard cable. The nominal probe DC resistance is 7.73 ± 0.50 ohms at 1.5 meters, critical for signal integrity. The linear range spans 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target, with a recommended gap setting for radial vibration of -9 Vdc (approximately 1.27 mm or 50 mils).

Industry Applications

This proximity probe is ideal for monitoring radial vibration and axial position in turbines, compressors, and pumps. In a steam turbine application, the 330104-00-09-15-01-00 provides real-time shaft displacement data, enabling early detection of misalignment or bearing wear. Its robust design withstands temperatures from -52°C to +177°C for standard probes, and up to +218°C for the tip in extended range versions, making it suitable for high-temperature environments. The probe also maintains less than a 3% change in Average Scale Factor (ASF) in 93% humidity, ensuring reliability in harsh conditions.

Installation & Setup Guidance

Proper installation is essential for accurate readings. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a 3-conductor shielded triad cable and tinned wiring. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Mount the probe with the M10x1 thread, ensuring thread engagement does not exceed 15 mm. Set the gap to approximately -9 Vdc for radial vibration monitoring, which corresponds to about 1.27 mm (50 mils) from the target. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal.

Maintenance & Reliability

Regular inspection of the probe and cable for physical damage is recommended. The stainless steel case and PPS tip resist wear and corrosion, but verify the O-ring seal integrity periodically. For applications requiring intrinsic safety, the probe can be installed with zener barriers per drawing 141092 or galvanic isolators, meeting Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga. For non-incendive circuits, use drawing 140979 for Class I, Zone 2 compliance. Always follow manufacturer guidelines for maintenance to ensure long service life.

Selection Guide & Purchasing Advice

When ordering the 330104-00-09-15-01-00, verify the unthreaded length (00 mm), overall case length (90 mm), and total length (1.5 m) match your application. The miniature coaxial ClickLoc connector with standard cable is included.
