Bently Nevada 330104-08-15-10-02-05 3300 XL 8 mm Proximity Probe

Product Overview

When precise vibration monitoring is critical for rotating machinery, the Bently Nevada 330104-08-15-10-02-05 delivers reliable performance. This 3300 XL 8 mm proximity probe is designed for non-contact displacement measurements in harsh industrial environments. With M10 x 1 thread and integral armor, it withstands demanding conditions while providing accurate data for predictive maintenance.

Technical Specifications Breakdown

The 330104-08-15-10-02-05 features an unthreaded length of 80 mm, overall case length of 150 mm, and total length of 1.0 meter (3.3 feet). Its miniature coaxial ClickLoc connector ensures secure, quick installation. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel. Nominal probe DC resistance is 7.59 ± 0.50 Ω. The probe is designed to seal differential pressure between tip and case using a Viton O-ring.

Industry Applications

This proximity probe excels in monitoring vibration and position of turbines, compressors, pumps, and motors. In oil and gas, power generation, and petrochemical plants, the 330104-08-15-10-02-05 helps prevent unplanned downtime by detecting shaft displacement and vibration anomalies early. Its robust construction suits Zone 0 and Zone 2 hazardous areas with appropriate barriers.

Installation & Setup Guidance

Mount the probe using the M10 x 1 thread into a pre-tapped hole. Ensure the target surface is clean and made of AISI 4140 steel for optimal accuracy. Gap the probe at 1.27 mm (50 mils) during installation. Connect the miniature coaxial ClickLoc connector to the extension cable and proximitor sensor. Use the specified power supply range of -17.5 Vdc to -26 Vdc for non-incendive circuits, or -23 Vdc to -26 Vdc with barriers.

Maintenance & Reliability

Inspect the probe tip and cable periodically for physical damage or contamination. Verify the O-ring seal integrity to maintain differential pressure sealing. The PPS tip resists many chemicals, but avoid abrasive contact. Follow the temperature schedule for ambient conditions: for EPL Ga and Gc, T5 rating allows -55°C to +40°C; T4 allows -55°C to +80°C; T3 allows -55°C to +120°C; T2 allows -55°C to +177°C; T1 allows -55°C to +232°C. For EPL Dc, refer to specific temperature classifications.

Compatibility & Integration

The 330104-08-15-10-02-05 is part of the 3300 XL system and works with 3300-series 5 mm and 3300 XL 8 mm proximitor sensors and extension cables. It accepts a -24 Vdc power supply with a 10 kΩ load. When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, it meets Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga; Class 1, Groups A, B, C, D; Class II, Groups E, F, G; Class III. For non-incendive circuits per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc; Class 1, Division 2, Groups A, B, C, D; Class I, Zone 2: AEx/Ex ec IIC T5…T1 Gc.
