Bently Nevada 330103-00-05-10-01-05 3300 XL 8 mm Proximity Probe

Product Overview

The Bently Nevada 330103-00-05-10-01-05 is a 3300 XL 8 mm Proximity Probe designed for precise vibration and position measurements in critical rotating machinery. This probe features an M10 x 1 thread, a 50 mm overall case length, and a 1.0 meter (3.3 feet) cable with a miniature coaxial ClickLoc connector and connector protector. It is constructed with a polyphenylene sulfide (PPS) probe tip and AISI 303 or 304 stainless steel case, ensuring durability in harsh industrial environments. The probe carries CSA, ATEX, and IECEx approvals for use in hazardous areas.

Technical Specifications Breakdown

Key parameters for the 330103-00-05-10-01-05 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 precise gap setting capability make it suitable for radial vibration and axial position measurements. The CSA, ATEX, and IECEx approvals allow installation in hazardous zones such as Class I, Zone 0 (with intrinsic safety barriers) or Zone 2 (with non-incendive circuits). Compared to other 8 mm probes, the 3300 XL series offers enhanced temperature tolerance and robust sealing, reducing failure risks in high-heat applications.

Installation & Setup Guidance

Mount the probe using the M10 x 1 thread with a maximum engagement of 15 mm. For radial vibration, set the initial gap to approximately -9 Vdc (1.27 mm or 50 mils). Use 3-conductor shielded triad cable with 0.2 to 1.5 mm² (16 to 24 AWG) tinned field wiring. The maximum cable length between the probe and the 3300 XL Proximitor Sensor is 305 meters (1,000 feet). Ensure the probe tip is clean and free of debris before installation. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage or wear. The probe is designed to seal differential pressure between the tip and case using a Viton O-ring, but it is not pressure tested before shipment. For applications requiring pressure seal verification, contact the custom design department. The probe exhibits less than 3% change in Average Scale Factor (ASF) when tested at 93% humidity per IEC standard 68-2-3 for up to 56 days, indicating moisture resistance.

Compatibility & Integration

The 330103-00-05-10-01-05 integrates with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. For hazardous area installations, use intrinsically safe zener barriers per drawing 141092 or galvanic isolators for Class I, Zone 0 (AEx/Ex ia IIC T5...T1 Ga). For non-incendive circuits per drawing 140979, it is suitable for Class I, Zone 2 (AEx/Ex nA IIC T5...T1 Gc). Always follow the specific wiring diagrams provided by Bently Nevada.

Selection Guide & Purchasing Advice

When selecting a proximity probe, consider the required cable length, thread size, and agency approvals. For longer cables or different thread options, explore other 3300 XL configurations. Contact AutoDCSTech for availability and lifecycle status before ordering.

Troubleshooting & Common Issues

If the probe output is unstable, verify the gap setting and cable connections. Check for physical damage to the probe tip or cable. Ensure the field wiring length does not exceed 305 meters to avoid signal roll-off at high frequencies. For erratic readings, inspect the target surface for runout or contamination. If the probe fails to calibrate, confirm the DC resistance is within 7.59 ± 0.50 Ω for a 1.0 m probe.
