Bently Nevada 330103-00-16-10-02-05 3300 XL 8 mm Proximity Probe, Metric

Technical Specifications Breakdown

Key parameters for the 330103-00-16-10-02-05 are listed below for quick reference:

Industry Applications: Reducing Total Cost of Ownership

This probe is widely used in critical rotating assets such as steam turbines, centrifugal compressors, and large pumps. In a typical refinery, a single unplanned outage can exceed $100,000 per day. By integrating the 3300 XL probe into a condition monitoring system, operators can detect shaft orbit changes or bearing wear early, schedule maintenance during planned shutdowns, and avoid expensive emergency repairs. The stainless steel case and PPS tip provide durability in harsh environments, reducing replacement frequency and lifecycle costs.

Installation & Setup Guidance

Proper installation is key to maximizing probe life and measurement accuracy. 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 probe and the monitor is 305 meters (1,000 feet); longer runs may cause signal roll-off at high frequencies. Set the initial gap to -9 Vdc (approximately 1.27 mm) for radial vibration measurements. Ensure the target surface is clean and free of runout for optimal linearity.

Maintenance & Reliability

The probe requires minimal routine maintenance. Inspect the cable and connector periodically for damage, especially in high-vibration or high-temperature areas. The probe is designed to seal differential pressure between tip and case using a Viton O-ring; avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature seal failure. The probe's resistance should be checked against the nominal value of 7.59 ± 0.50 Ω to verify integrity. For extended temperature range applications, the probe tip can withstand up to 218°C (425°F) and the cable up to 260°C (500°F).

Cost-Effective Vibration Monitoring with the Bently Nevada 3300 XL Probe

For industrial rotating machinery, unplanned downtime from bearing or shaft failures can cost tens of thousands per hour. The Bently Nevada 330103-00-16-10-02-05 3300 XL 8 mm Proximity Probe offers a proven, cost-efficient solution for continuous radial vibration and position monitoring. By providing early warning of developing faults, this probe helps avoid catastrophic failures and extends equipment life, delivering a strong return on investment.

Compatibility & Integration

The 330103-00-16-10-02-05 is part of the 3300 XL family and is compatible with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. It supports both standard and intrinsically safe installations when using approved zener barriers or galvanic isolators per drawing 141092, or non-incendive circuits per drawing 140979. This flexibility allows integration into various hazardous area classifications, including Class I, Zone 0 and Zone 2 environments.

Selection Guide & Purchasing Advice

When selecting a proximity probe, consider the required cable length, thread size, and agency approvals. The 330103-00-16-10-02-05 offers a 1.0-meter cable, M10 x 1 thread, and CSA/ATEX/IECEx certifications, making it suitable for global applications.
