Bently Nevada 330103-00-04-05-02-RU 3300 XL 8 mm Proximity Probe

Technical Specifications Breakdown

Key parameters for the 330103-00-04-05-02-RU are listed below for quick reference:

Industry Applications for Reliable Protection

Typical applications include:

• Steam and Gas Turbines: Monitor radial vibration and thrust position to prevent catastrophic failure.
• Centrifugal Compressors: Detect shaft instability and imbalance in high-speed rotating trains.
• Pumps and Motors: Provide early warning of bearing wear or misalignment.

With a linear range of 2 mm (80 mils) starting at 0.25 mm (10 mils) from the target, and a recommended radial vibration gap setting of -9 Vdc (approximately 1.27 mm / 50 mils), this probe delivers the accuracy needed for condition-based maintenance.

Installation and Setup Guidance

Proper installation ensures measurement integrity. The probe case thread is M10x1 with a maximum thread engagement of 15 mm. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) 3-conductor shielded triad cable with tinned ends. Maximum cable length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet).

When installed with intrinsically safe zener barriers per drawing 141092 or galvanic isolators, the probe is rated Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga. For non-incendive circuits per drawing 140979, it meets Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc.

Maintenance and Reliability

The probe is designed to seal differential pressure between tip and case using a Viton® O-ring. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. The probe shows less than a 3% change in Average Scale Factor (ASF) when tested in 93% humidity per IEC 68-2-3 for up to 56 days. Inspect the cable and connector periodically for damage.

Precision Vibration Monitoring for Critical Machinery

When uptime is non-negotiable, accurate proximity measurement forms the backbone of your protection system. The Bently Nevada 330103-00-04-05-02-RU is a 3300 XL 8 mm Proximity Probe designed for reliable, continuous monitoring of shaft vibration and position in rotating equipment.

This metric probe features an M10 x 1 thread without armor, a polyphenylene sulfide (PPS) tip, and a 40 mm overall case length. The 0.5 meter (1.6 feet) cable terminates with a miniature coaxial ClickLoc connector for secure, quick installation. The Country Specific (RU) agency approval ensures compliance with local standards.

Compatibility and Integration

This probe is part of the 3300 XL series and works with 3300 XL Proximitor Sensors and compatible monitoring systems. The nominal DC resistance from center conductor to outer conductor is 7.45 ± 0.50 ohms for a 1.0 m probe length. Ensure your monitor supports the -1 to -17 Vdc output range over the linear span.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify your required thread size, cable length, and connector type. The 330103-00-04-05-02-RU is a metric, unarmored probe with a 0.5 m cable and ClickLoc connector. For assistance with lifecycle status or alternative configurations, contact AutoDCSTech.
