Bently Nevada 330103-00-05-10-11-05 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330103-00-05-10-11-05 is a 3300 XL 8 mm proximity probe designed for reliable shaft vibration and position monitoring in rotating machinery. This model features an M10 x 1 thread without armor, a 50 mm overall case length, and a 1.0 meter (3.3 feet) total length. It includes a miniature coaxial ClickLoc connector with connector protector and FluidLoc cable, plus CSA, ATEX, and IECEx approvals for hazardous area use. The probe tip is made of polyphenylene sulfide (PPS), and the case is AISI 303 or 304 stainless steel.

Technical Specifications Breakdown

Key parameters for the 330103-00-05-10-11-05 are listed below for quick reference:

Industry Applications

This proximity probe is widely used in turbomachinery monitoring, including steam turbines, compressors, and pumps. Its 2 mm linear range and -9 Vdc recommended gap setting enable accurate radial vibration and axial position measurements. The CSA, ATEX, and IECEx approvals allow installation in hazardous locations such as oil and gas facilities, chemical plants, and power generation stations. The robust PPS tip and stainless steel case withstand harsh environments, reducing unplanned downtime.

Installation & Setup Guidance

When installing the 330103-00-05-10-11-05, ensure the probe tip is clean and the target surface is smooth. Use a 3-conductor shielded triad cable with tinned field wiring (0.2 to 1.5 mm² / 16 to 24 AWG). The maximum field wiring length between the probe and the 3300 XL Proximitor Sensor is 305 meters (1,000 feet). For radial vibration applications, set the gap to approximately -9 Vdc (1.27 mm / 50 mils). Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. Verify thread engagement does not exceed 15 mm for M10 x 1 threads.

Maintenance & Reliability

Periodically inspect the probe cable and connector for damage, especially in high-vibration or high-temperature areas. The probe sealing material includes a Viton® O-ring; do not disassemble the probe. If pressure seal integrity is critical, contact the custom design department for testing. The probe exhibits less than 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC 68-2-3 for up to 56 days, ensuring reliable performance in humid environments.

Compatibility & Integration

This probe is designed for use with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. It supports both intrinsic safety (with zener barriers per drawing 141092 or galvanic isolators) and non-incendive installations (per drawing 140979). The ClickLoc connector simplifies field wiring and provides a secure connection. The probe is compatible with standard 3300 XL system configurations.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the thread size (M10 x 1), overall length, and cable length match your application. The 330103-00-05-10-11-05 includes CSA, ATEX, and IECEx approvals, making it suitable for global hazardous area use. For pricing and availability, contact AutoDCSTech.
