Bently Nevada 330103-00-03-90-12-00 3300 XL 8 mm Proximity Probe

Product Overview

For maintenance engineers overseeing rotating machinery, precise vibration measurement is non-negotiable. The Bently Nevada 330103-00-03-90-12-00 is a 3300 XL 8 mm Proximity Probe designed for reliable, continuous monitoring in harsh industrial environments. This probe provides accurate displacement readings, helping you detect early signs of bearing wear, imbalance, or misalignment before they lead to unplanned downtime.

Technical Specifications Breakdown

Key parameters for the 330103-00-03-90-12-00 are listed below for quick reference:

Industry Applications

Its PPS tip and stainless steel case withstand oil mist, moisture, and temperature swings common in power generation and petrochemical plants.

Installation & Setup Guidance

Mount the probe with M10 x 1 threads, ensuring thread engagement does not exceed 15 mm. Use 3-conductor shielded triad cable (16 to 24 AWG) for field wiring, keeping the distance between the Proximitor Sensor and monitor under 305 meters (1,000 feet) to avoid signal roll-off at high frequencies. Set the initial gap to approximately 1.27 mm (50 mils) for radial vibration monitoring, corresponding to -9 Vdc output.

Maintenance & Reliability

Inspect the probe cable and connector periodically for signs of wear or fluid ingress. The FluidLoc cable and ClickLoc connector are designed for reliable performance in wet or corrosive environments. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. The probe is not pressure tested before shipment; contact the custom design department if a pressure seal test is required.

Compatibility & Integration

This probe works with Bently Nevada 3300 XL Proximitor Sensors and compatible monitoring systems. When installed with intrinsically safe zener barriers (per drawing 141092) or galvanic isolators, the probe meets 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 requirements. For non-incendive installations (per drawing 140979), it qualifies as Class I, Zone 2: AEx/Ex nA IIC T5…T1 Gc; Class 1, Division 2, Groups A, B, C, D.

Selection Guide & Purchasing Advice

When selecting a replacement or spare probe, verify your required total length, thread size, and connector type. The 330103-00-03-90-12-00 offers a 9.0 m cable with a miniature coaxial ClickLoc connector. For lifecycle status and availability, contact AutoDCSTech before ordering.
