Bently Nevada 330101-20-35-10-02-05 3300 XL 8 mm Probe

Technical Specifications Breakdown

Key parameters for the 330101-20-35-10-02-05 are listed below for quick reference:

Industrial Applications

This probe is engineered for continuous vibration monitoring on turbines, compressors, pumps, and other rotating equipment. The 2 mm linear range and high sensitivity (7.87 V/mm) allow early detection of shaft displacement and bearing wear. The CSA, ATEX, and IECEx approvals make it suitable for hazardous area installations, reducing the risk of catastrophic failure.

Installation and Setup Guidance

Mount the probe using the 3/8-24 UNF thread into a drilled and tapped hole per manufacturer guidelines. Ensure the probe tip is clean and the target surface is smooth. For radial vibration measurements, set the gap to -9 Vdc (approximately 1.27 mm). Use 3-conductor shielded triad cable for field wiring, with a maximum length of 305 meters (1,000 feet) between the probe and monitor. Verify the connector is fully seated to maintain signal integrity.

Maintenance and Reliability

The probe case is made of AISI 303 or 304 stainless steel, offering corrosion resistance in harsh environments. The probe tip is encapsulated in PPS plastic, providing robustness against physical abuse. Regularly inspect the cable and connector for damage. The patented CableLoc design provides 330 N (75 lbf) pull strength to prevent cable detachment. Store and operate within the standard temperature range of -52°C to +177°C.

Precision Vibration Monitoring with the Bently Nevada 330101-20-35-10-02-05

When protecting critical rotating machinery, accurate and reliable vibration measurement is non-negotiable. The Bently Nevada 330101-20-35-10-02-05 is a 3300 XL 8 mm probe designed for demanding industrial environments. This probe uses a 3/8-24 UNF thread and comes without armor, making it suitable for installations where space and weight are considerations.

Compatibility and Integration

This probe is part of the 3300 XL series and is compatible with Bently Nevada Proximitor sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures a secure, noise-resistant connection. For systems requiring extended temperature range, refer to the ETR specifications for 5 and 9 meter systems.

Selection Guide and Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), unthreaded length (2.0 in), and overall case length (3.5 in). For hazardous area use, the CSA, ATEX, and IECEx approvals are included. Contact AutoDCSTech for availability and lifecycle status before ordering.
