Bently Nevada 330104-05-17-10-11-05 3300 XL 8 mm Proximity Probe, Metric

Product Overview

When unplanned downtime drives up maintenance costs, the Bently Nevada 330104-05-17-10-11-05 3300 XL 8 mm Proximity Probe delivers reliable shaft vibration and position measurement. This metric probe uses a 1.0 meter (3.3 feet) cable with a miniature coaxial ClickLoc connector and FluidLoc cable, ensuring stable signal transmission in demanding industrial environments. Its polyphenylene sulfide (PPS) tip and AISI 303 or 304 stainless steel case resist wear, reducing replacement frequency and long-term expenses.

Technical Specifications Breakdown

The 330104-05-17-10-11-05 offers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. This precise measurement window minimizes false readings and costly misdiagnoses. The recommended radial vibration gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) ensures optimal sensitivity, directly improving machine protection and reducing unexpected failures. Nominal probe DC resistance is 7.59 ± 0.50 ohms at 1.0 meter length, providing consistent electrical performance that lowers calibration time and associated labor costs.

Industry Applications

In turbine and compressor monitoring, the 330104-05-17-10-11-05 detects early shaft vibration anomalies, allowing maintenance teams to schedule repairs rather than face emergency shutdowns. For pump and motor protection, its 2 mm linear range covers typical clearance variations, reducing false alarms that lead to unnecessary inspections. By integrating this probe into a condition-based maintenance program, facilities can cut spare parts inventory and extend equipment life, directly improving return on investment.

Installation & Setup Guidance

Mount the probe using its M10x1 thread with a maximum thread engagement of 15 mm. Use field wiring from 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable, tinned for reliable connections. Keep the distance between the 3300 XL Proximitor Sensor and the monitor within 305 meters (1,000 feet) to maintain signal integrity. Proper gap setting at -9 Vdc ensures the probe operates in its linear range, avoiding costly rework.

Maintenance & Reliability

The probe operates from -52°C to +177°C (-62°F to +350°F) in standard configuration, with extended temperature range options for higher thermal environments. Exposing the probe below -34°C (-30°F) may degrade the pressure seal, so verify ambient conditions to avoid premature failure. The probe weight of 323 g/m (11.4 oz) and robust stainless steel case reduce mechanical stress on mounting brackets, lowering long-term support costs. Regular inspection of the connector and cable for damage is recommended to maintain measurement accuracy.

Selection Guide & Purchasing Advice

Before ordering, confirm that the unthreaded length (50 mm), overall case length (170 mm), and total length (1.0 meter) match your installation requirements. The 330104-05-17-10-11-05 includes CSA, ATEX, and IECEx approvals for hazardous area use.
