Bently Nevada 330104-00-08-10-02-CN 3300 XL 8 mm Proximity Probe for Vibration Monitoring

Introduction

When unexpected machine downtime threatens production targets, the Bently Nevada 330104-00-08-10-02-CN 3300 XL 8 mm Proximity Probe delivers precise, non-contact displacement measurements for critical rotating equipment. This probe is part of the trusted 3300 XL series, engineered for harsh industrial environments where reliability is paramount.

Technical Specifications Breakdown

The 330104-00-08-10-02-CN features a probe tip made of Polyphenylene sulfide (PPS) for excellent chemical resistance and durability. Its case is constructed from AISI 303 or 304 stainless steel (SST), ensuring robust mechanical integrity. The probe uses an M10 x 1 thread and includes armor for added protection. Key length options include an unthreaded length of 00 mm, an overall case length of 80 mm, and a total length of 1.0 meter (3.3 feet). The connector is a miniature coaxial ClickLoc type with standard cable, providing secure and reliable signal transmission. The nominal probe DC resistance from center conductor to outer conductor is 7.59 ± 0.50 Ω for the 1.0 m probe length. The probe is designed to seal differential pressure between the tip and case using a Viton® O-ring.

Industry Applications

This proximity probe excels in vibration and position monitoring for turbines, compressors, pumps, and motors. In a steam turbine application, the 330104-00-08-10-02-CN provides accurate shaft displacement data, enabling early detection of bearing wear or misalignment. Its robust stainless steel case and PPS tip withstand high temperatures and corrosive atmospheres common in petrochemical plants.

Installation & Setup Guidance

Proper installation is critical for accurate measurements. Mount the probe using the M10 x 1 thread, ensuring the target surface is clean and made of AISI 4140 steel for system accuracy. Gap the probe at 1.27 mm (50 mils) during calibration. Use only 3300 XL 8 mm extension cables and Proximitor sensors to maintain system performance. Verify the probe's DC resistance matches the specified 7.59 ± 0.50 Ω to confirm cable integrity.

Maintenance & Reliability

Regularly inspect the probe cable and connector for damage or wear. The Viton® O-ring seal should be checked during routine maintenance to ensure pressure integrity. Avoid exposing the probe to voltages outside the -17.5 Vdc to -26 Vdc range when connected to a non-incendive circuit. Periodic verification of the probe gap and output linearity helps sustain measurement accuracy over time.

Compatibility & Integration

The 330104-00-08-10-02-CN is designed for use with Bently Nevada 3300 XL 8 mm Proximitor sensors and extension cables. It accepts non-contacting 3300-series 5 mm or 3300 XL 8 mm probes. The system operates with a -24 Vdc power supply and a 10 kΩ load for standard performance. For optimal results, use only 3300 XL 8 mm components as a complete system.
