Bently Nevada 330101-00-84-20-02-00 3300 XL 8 mm Probe

Technical Specifications Breakdown

Key parameters for the 330101-00-84-20-02-00 are listed below for quick reference:

Industry Applications for Enhanced Machine Protection

Its 2 mm linear range and high sensitivity (7.87 V/mm) allow early detection of shaft vibration and position changes. In a steam turbine, for example, the probe’s robust PPS tip and stainless steel case withstand high temperatures and harsh lubricants, ensuring reliable data for balancing and alignment decisions. The patented TipLoc and CableLoc designs provide exceptional mechanical integrity, reducing false readings from cable stress.

Installation and Setup Guidance

Proper installation is key to accurate measurements. Mount the probe using the 3/8-24 UNF thread into a suitable fixture, ensuring the target surface is clean and conductive. The recommended gap setting for radial vibration is -9 Vdc (approximately 1.27 mm or 50 mils). Use field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a three-conductor shielded triad cable. Maximum field wiring length between the Proximitor Sensor and monitor is 305 meters (1,000 feet). Always verify the probe’s DC resistance (7.88 ± 0.50 Ω for the 2.0 m probe) to confirm cable integrity.

Maintenance and Reliability

Periodically inspect the probe cable and connector for damage, especially in high-vibration or high-temperature areas. The probe’s operating temperature range for standard models is -52°C to +177°C; avoid prolonged exposure below -34°C (-30°F) to prevent pressure seal failure. The Viton® O-ring seals differential pressure between tip and case. For extended temperature range probes, tip rating is -52°C to +218°C, with cable and connector rated to -51°C to +260°C. Keep the probe tip free of debris and conductive coatings.

Reliable Vibration Monitoring with the Bently Nevada 3300 XL 8 mm Probe

Unplanned downtime due to undetected machinery faults is a persistent challenge in industrial operations. The Bently Nevada 330101-00-84-20-02-00 3300 XL 8 mm Probe offers a robust solution for accurate, continuous vibration measurement, helping you avoid costly failures and extend equipment life. This non-contact eddy current probe is engineered for demanding environments, providing the data needed for effective predictive maintenance.

Compatibility and Integration

The miniature coaxial ClickLoc connector ensures a secure, quick connection. Standard system incremental scale factor is 7.87 V/mm ±5% over 0°C to +45°C. For 9-meter systems, ISF is ±6.5%. Deviation from best fit straight line is less than ±0.025 mm for standard 5 or 1 meter systems. This probe is designed as a direct replacement for existing 3300 XL installations.
