Bently Nevada 330102-00-17-50-11-CN 3300 XL 8 mm Proximity Probe

Product Overview

For engineers tasked with protecting critical rotating machinery, the Bently Nevada 330102-00-17-50-11-CN 3300 XL 8 mm Proximity Probe offers a proven solution for precise shaft vibration and position measurement. This component is designed for use with the 5 meter Proximitor sensor only, ensuring a matched system for reliable data acquisition. The probe features a polyphenylene sulfide (PPS) tip and a case made of AISI 303 or 304 stainless steel (SST), providing durability in demanding industrial environments. With a miniature coaxial ClickLoc connector and connector protector, along with FluidLoc cable, this probe simplifies installation while maintaining signal integrity.

Technical Specifications Breakdown

Key parameters for the 330102-00-17-50-11-CN are listed below for quick reference:

Industry Applications

The 2 mm linear range and -9 Vdc recommended gap setting allow precise measurement of shaft motion relative to the bearing housing. In a typical steam turbine train, using the 330102-00-17-50-11-CN with a 5-meter Proximitor sensor ensures consistent sensitivity and minimal signal degradation. The PPS tip resists chemical attack, making it suitable for applications where oil mist or process vapors are present. The stainless steel case withstands corrosion in humid or offshore environments.

Installation & Setup Guidance

When installing, ensure the probe is threaded into a mounting fixture with a maximum thread engagement of 0.563 inches for the 3/8-24 UNF thread. Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable and tinned wiring. The maximum field wiring length between the Proximitor sensor and the monitor is 305 meters (1,000 feet). For optimal frequency response, keep field wiring as short as possible, especially if high-frequency vibration components are expected. The probe is designed to seal differential pressure between the tip and case via a Viton® O-ring; avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal.

Maintenance & Reliability

Periodically inspect the probe cable and connector for signs of wear or damage. The FluidLoc cable provides resistance to moisture ingress, but regular visual checks are recommended. The probe operating temperature range is -52°C to +177°C (-62°F to +350°F) for standard versions; if the application requires higher temperatures, consider the extended range probe tip rated to +218°C (+425°F). Relative humidity testing shows less than a 3% change in Average Scale Factor (ASF) after 56 days at 93% humidity per IEC 68-2-3, confirming stable performance in wet conditions.

Compatibility & Integration

The 330102-00-17-50-11-CN is designed exclusively for use with the 5 meter 3300 XL Proximitor sensor. When installed with intrinsically safe zener barriers per drawing 141092 or with galvanic isolators, the probe achieves 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 ratings. Alternatively, with nonincendive circuit connection per drawing 140979, it qualifies for Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc; Class 1, Division 2, Groups A, B, C, D; and Class I, Zone 2: AEx/Ex ec llC T5…T1 Gc. Verify your system's hazardous area classification before selecting the appropriate barrier or isolator.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, confirm the total length option (50 = 5.0 meters) matches your existing Proximitor sensor cable length. The 330102-00-17-50-11-CN is available from AutoDCSTech, a trusted supplier of industrial automation parts. Please verify current lifecycle status and availability with AutoDCSTech before ordering.
