Bently Nevada 330103-00-04-10-02-CN 3300 XL 8 mm Proximity Probe, Metric

Technical Specifications Breakdown

Key parameters for the 330103-00-04-10-02-CN are listed below for quick reference:

Industry Applications

In a petrochemical plant, for example, a 3300 XL 8 mm probe mounted near a compressor bearing housing provides continuous shaft displacement data, enabling operators to detect imbalance or misalignment early. The 2 mm linear range and recommended -9 Vdc gap setting ensure consistent measurement across common machinery clearances. The PPS tip offers chemical resistance in process environments.

Installation & Setup Guidance

Mount the probe using the M10 x 1 thread with a maximum thread engagement of 15 mm. For field wiring, use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable with tinned ends. The maximum cable length between the 3300 XL Proximitor Sensor and the monitor is 305 meters (1,000 feet). Be aware that longer field wiring lengths may cause signal rolloff at high frequencies; refer to the frequency response graphs in the manual. Set the initial gap to approximately -9 Vdc (1.27 mm) for radial vibration applications.

Maintenance & Reliability

The probe case is constructed from AISI 303 or 304 stainless steel, providing corrosion resistance in typical industrial atmospheres. The probe sealing material uses a Viton® O-ring to maintain differential pressure integrity. Note that probes are not pressure tested before shipment. Exposing the probe to temperatures below -34°C (-30°F) may cause premature failure of the pressure seal. Inspect the cable and connector periodically for damage, especially in high-vibration or high-temperature locations.

Solving Vibration Monitoring Challenges in Rotating Machinery

In critical rotating machinery such as steam turbines, centrifugal compressors, and large pumps, accurate shaft vibration measurement is essential for predictive maintenance and machine protection. The Bently Nevada 330103-00-04-10-02-CN 3300 XL 8 mm Proximity Probe addresses the challenge of obtaining reliable, repeatable displacement data in harsh industrial environments. This metric probe, part of the proven 3300 XL series, delivers the precision needed for early fault detection.

Compatibility & Integration

This probe is designed for use with Bently Nevada 3300 XL Proximitor Sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures a secure, quick connection. For intrinsically safe installations, the probe can be used with zener barriers per drawing 141092 or with galvanic isolators, achieving Class I, Zone 0: AEx/Ex ia IIC T5...T1 Ga. For non-incendive circuits, use per drawing 140979 for Class I, Zone 2 applications.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the required thread size, cable length, and agency approvals. The 330103-00-04-10-02-CN is a country-specific model.
