Bently Nevada 330102-00-10-10-01-05 3300 XL 8 mm Proximity Probe

Product Overview

The 330102-00-10-10-01-05 is a 3300 XL 8 mm Proximity Probe from Bently Nevada, a trusted brand in industrial vibration monitoring. It features a 3/8-24 UNF thread with armor, a 1.0 meter cable length, and a miniature coaxial ClickLoc connector with connector protector. The probe tip is made of polyphenylene sulfide (PPS), and the case is constructed from AISI 303 or 304 stainless steel. This model carries CSA, ATEX, and IECEx approvals, making it suitable for hazardous area installations.

Technical Specifications Breakdown

Key parameters for the 330102-00-10-10-01-05 are listed below for quick reference:

Industry Applications

Its linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target, provides the sensitivity needed for early fault detection. The recommended gap setting of -9 Vdc (approximately 1.27 mm or 50 mils) ensures optimal signal linearity. With a standard temperature range of -52°C to +177°C, the 330102-00-10-10-01-05 performs reliably in high-temperature turbine applications.

Installation & Setup Guidance

Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned wiring. The maximum length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). For proper sealing, note that the probe uses a Viton® O-ring and is designed to seal differential pressure between the tip and case. The maximum thread engagement for the 3/8-24 thread is 0.563 inches.

Maintenance & Reliability

Regular inspection of the probe cable and connector is recommended, especially in environments with high humidity or temperature cycling. The probe exhibits less than a 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC standard 68 2 3 for up to 56 days. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal.

Solving Vibration Monitoring Challenges in Rotating Machinery

Engineers tasked with protecting critical rotating assets—such as steam turbines, compressors, and large pumps—face a persistent challenge: obtaining accurate, repeatable shaft vibration data in extreme conditions. The Bently Nevada 330102-00-10-10-01-05, a 3300 XL 8 mm Proximity Probe, directly addresses this need. Designed for continuous operation in high-temperature and high-humidity environments, this probe delivers the precision required for reliable machinery protection systems.

Compatibility & Integration

This probe is designed for use with the 3300 XL Proximitor Sensor system. For 5-meter probes, use the 5-meter Proximitor sensor; for 9-meter systems, use 330101 probes. The 330102-00-10-10-01-05 is compatible with intrinsically safe installations when used with zener barriers per drawing 141092 or galvanic isolators, achieving Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga.

Selection Guide & Purchasing Advice

When selecting a proximity probe, verify the required cable length, thread size, and agency approvals match your installation. The 330102-00-10-10-01-05 is available from AutoDCSTech, a trusted supplier of industrial automation parts. Please verify current lifecycle status and availability with AutoDCSTech before ordering.

Troubleshooting & Common Issues

If readings are erratic, first check the cable and connector for damage. Ensure the probe gap is set to the recommended -9 Vdc. Verify that the field wiring length does not exceed 305 meters to avoid signal roll-off at high frequencies. If the pressure seal is compromised, contact the custom design department for testing options.
