Bently Nevada 330101-00-67-20-02-00 3300 XL 8 mm Probe, 3/8-24 UNF Thread, Without Armor

Technical Specifications Breakdown

Key parameters for the 330101-00-67-20-02-00 are listed below for quick reference:

Industrial Applications

Its thicker PPS tip encapsulation and robust stainless steel case provide superior durability compared to smaller probes. Typical uses include:

• Steam Turbine Monitoring: The probe’s extended temperature range (up to +177°C standard) suits high-temperature environments near turbine bearings.
• Compressor Vibration Analysis: With a linear range of 2 mm and ISF of 7.87 V/mm, it delivers precise shaft displacement measurements for early fault detection.
• Pump Protection: The patented CableLoc design offers 330 N (75 lbf) pull strength, reducing cable failure risks in high-vibration pump applications.

Installation & Setup Guidance

For optimal performance, mount the probe using the 3/8-24 UNF thread in a suitable bracket or casing. 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 length between the Proximitor sensor and monitor is 305 meters (1,000 feet). Ensure the probe tip is clean and free of debris before installation.

Maintenance & Reliability

Inspect the probe and cable periodically for signs of wear, especially in high-temperature or humid conditions. The probe is designed to seal differential pressure with a Viton O-ring but is not pressure tested before shipment. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature pressure seal failure. For extended temperature range applications, the probe tip can operate up to +218°C (+425°F) and the cable up to +260°C (+500°F).

Robust Vibration Sensing for Critical Machinery

When protecting rotating assets like turbines, compressors, and pumps, accurate vibration measurement is non-negotiable. The Bently Nevada 330101-00-67-20-02-00 3300 XL 8 mm probe delivers the ruggedness and precision required for continuous monitoring in harsh industrial environments. This non-contact probe is engineered to provide reliable data for predictive maintenance, helping you avoid unplanned downtime.

Compatibility & Integration

This 3300 XL probe is designed for use with Bently Nevada Proximitor sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures secure, quick connections. The probe’s standard cable capacitance of 69.9 pF/m (21.3 pF/ft) typical supports consistent signal transmission over long distances.

Selection Guide & Purchasing Advice

When selecting a replacement or new probe, verify the thread size (3/8-24 UNF), overall case length (6.7 in), and total cable length (2.0 m). The 330101-00-67-20-02-00 is a non-armored version; for armored requirements, consult Bently Nevada options. AutoDCSTech stocks this exact model to support your critical machinery monitoring needs.
