Bently Nevada 330104-00-40-10-02-CN 3300 XL 8 mm Proximity Probe

Product Overview

When critical rotating machinery requires precise vibration and position monitoring, the Bently Nevada 330104-00-40-10-02-CN delivers reliable performance. This 3300 XL 8 mm proximity probe is part of the trusted 3300 XL series, engineered for demanding industrial environments. With an M10 x 1 thread and integral armor, it withstands harsh conditions while providing accurate measurements. The probe features a 1.0-meter (3.3 feet) total length and a miniature coaxial ClickLoc connector for secure, quick installation. Its probe tip is made of polyphenylene sulfide (PPS), and the case is constructed from AISI 303 or 304 stainless steel (SST), ensuring durability and corrosion resistance. This model includes country-specific approval (CN) for applicable regional standards.

Technical Specifications

The 330104-00-40-10-02-CN offers key specifications that define its performance. The probe has an unthreaded length of 0 mm and an overall case length of 40 mm. Total length is 1.0 meter (3.3 feet). The connector option is a miniature coaxial ClickLoc connector with standard cable. Nominal probe DC resistance (RPROBE) from center conductor to outer conductor is 7.59 ± 0.50 Ω for the 1.0-meter probe length. The probe tip material is polyphenylene sulfide (PPS), and the probe case material is AISI 303 or 304 stainless steel (SST). The probe is designed to seal differential pressure between the probe tip and case using a Viton® O-ring. These specifications ensure consistent, reliable operation in vibration and proximity sensing applications.

Industry Applications

This proximity probe is ideal for monitoring rotating equipment such as turbines, compressors, pumps, and motors in industries like oil and gas, power generation, and manufacturing. Its 8 mm diameter and robust construction make it suitable for installations where space is limited and environmental conditions are demanding. The 330104-00-40-10-02-CN provides accurate shaft vibration and position data, helping to prevent unplanned downtime and extend machinery life. By integrating this probe into a 3300 XL system, operators gain actionable insights for predictive maintenance strategies.

Installation & Setup Guidance

Proper installation is critical for accurate measurements. Mount the probe using the M10 x 1 threaded section, ensuring the tip is positioned at the correct gap relative to the target surface. For optimal performance, use only 3300 XL 8 mm extension cables and a compatible 3300 XL Proximitor Sensor. Follow the manufacturer's guidelines for cable routing to avoid damage and signal interference. The ClickLoc connector simplifies cable attachment and provides a secure connection. Verify the probe gap and target material (AISI 4140 steel is recommended for calibration) to achieve specified accuracy.

Maintenance & Reliability

Routine inspection of the probe and cable assembly helps maintain reliable operation. Check for physical damage, wear, or contamination on the probe tip and cable. The stainless steel case and PPS tip resist corrosion and chemical exposure, but periodic cleaning with a soft, dry cloth is advisable. Ensure the Viton® O-ring remains intact to preserve the pressure seal. For systems with barriers, verify that the power supply meets the required voltage range (-17.5 Vdc to -26 Vdc) to avoid reduced linear range. Following these practices maximizes probe lifespan and measurement accuracy.

Selection Guide & Purchasing Advice

When selecting the 330104-00-40-10-02-CN, verify that the probe length, thread type, and connector match your system requirements. This model is designed for use with 3300 XL 8 mm Proximitor Sensors and extension cables.
