Bently Nevada 330104-00-20-10-01-CN 3300 XL 8 mm Proximity Probe

Product Overview

In the evolution of industrial monitoring, the need for precise, non-contact measurement of shaft vibration and position has driven innovation in proximity probe technology. The Bently Nevada 330104-00-20-10-01-CN represents a key advancement in this field, offering a robust solution for demanding rotating machinery applications. As part of the 3300 XL 8 mm series, this probe delivers consistent performance for critical asset protection.

Technical Specifications

The 330104-00-20-10-01-CN is a 3300 XL 8 mm proximity probe with an M10 x 1 thread and armor for enhanced durability. It features an unthreaded length of 00 mm, an overall case length of 200 mm, and a total length of 1.0 meter (3.3 feet). The connector and cable option is a miniature coaxial ClickLoc connector with connector protector and standard cable. The agency approval option is CN Country Specific.

The probe tip material is polyphenylene sulfide (PPS), and the probe case material is AISI 303 or 304 stainless steel (SST). The probe is designed to seal differential pressure between the probe tip and case using a Viton O-ring. For electrical performance, the system accepts one non-contacting 3300-series 5 mm or 3300 XL 8 mm proximity probe and extension cable. It requires -17.5 Vdc to -26 Vdc power supply with non-incendive circuit connection per installation drawing 140979 at 12 mA maximum consumption, or -23 Vdc to -26 Vdc with barriers. The nominal probe DC resistance (RPROBE) from center conductor to outer conductor for a 1.0 m probe is 7.59 ± 0.50 ohms.

Industry Applications

This proximity probe is ideal for monitoring radial vibration and axial position in turbines, compressors, pumps, and other rotating equipment. In petrochemical plants, the 330104-00-20-10-01-CN helps detect early signs of shaft misalignment or bearing wear, enabling predictive maintenance. Its robust construction and PPS tip ensure reliable operation in harsh environments, reducing unplanned downtime.

Installation Guidance

Proper installation is critical for accurate measurements. Mount the probe with the M10 x 1 thread into a suitable bracket or housing, ensuring the probe tip is gapped at 1.27 mm (50 mils) for optimal performance. Use the miniature coaxial ClickLoc connector for secure cable attachment. Verify that the system is calibrated to an AISI 4140 steel target as specified for accuracy and interchangeability.

Maintenance & Reliability

Regular inspection of the probe and cable for physical damage is recommended. The Viton O-ring seal should be checked periodically to maintain differential pressure integrity. Environmental factors such as temperature and altitude (maximum 2000 meters) affect performance; ensure operation within specified ranges for consistent results. The 330104-00-20-10-01-CN is designed for long service life with minimal maintenance.

Compatibility & Integration

This probe works exclusively with 3300 XL 8 mm system components, including the 3300 XL Proximitor Sensor and extension cable. It is compatible with Bently Nevada monitoring systems that accept non-contacting proximity transducers. For best results, use only 3300 XL 8 mm components to maintain system accuracy and interchangeability.
