Bently Nevada 330101-00-61-15-02-CN 3300 XL 8 mm Probe

Technical Specifications Breakdown

Key parameters for the 330101-00-61-15-02-CN are listed below for quick reference:

Industry Applications for Reliable Measurement

The thicker PPS encapsulation of the probe coil and larger body diameter provide superior resistance to abuse compared to smaller probes. Typical applications include:

• Steam Turbine Vibration Monitoring: The 2 mm linear range (0.25 to 2.3 mm from target) and -9 Vdc recommended gap setting for radial vibration allow precise shaft relative vibration measurement.
• Centrifugal Compressor Thrust Position: The probe's stable Incremental Scale Factor (7.87 V/mm ± 5% over the linear range from 0°C to +45°C) ensures accurate axial position readings.
• Pump Bearing Housing Monitoring: The standard temperature range (-52°C to +177°C) covers most industrial pump operating conditions, while the optional FluidLoc cable prevents oil leakage through the cable interior.

Installation & Setup Guidance

Proper installation is critical for accurate readings. The probe case thread is 3/8-24 UNF, with a maximum thread engagement of 0.563 inches. For standard forward-mounted probes, use the recommended torque of 11.2 N•m (100 in•lbf) for the case, and 7.5 N•m (66 in•lbf) for the first three threads. Field wiring should use 0.2 to 1.5 mm² (16 to 24 AWG) three-conductor shielded triad cable, with a maximum length of 305 meters (1,000 feet) between the 3300 XL Proximitor Sensor and the monitor. Always verify the target material and surface condition per manufacturer guidelines.

Maintenance & Reliability

The 3300 XL probe is designed for long-term reliability in harsh environments. The probe sealing material consists of a Viton® O-ring to seal differential pressure between tip and case. Probes are not pressure tested prior to shipment; contact the custom design department if pressure seal testing is required. Relative humidity exposure of up to 93% for 56 days results in less than a 3% change in Average Scale Factor (ASF). Inspect probe cables and connectors periodically for wear or damage, especially in high-vibration or high-temperature areas.

Robust Vibration Monitoring for Critical Machinery

For engineers tasked with protecting rotating assets, the Bently Nevada 330101-00-61-15-02-CN 3300 XL 8 mm Probe delivers the measurement integrity required for reliable condition monitoring. This non-contact proximity probe is designed for radial vibration and position measurement in compressors, turbines, pumps, and other critical machinery. The 3300 XL series incorporates patented TipLoc and CableLoc technologies, providing a robust bond between probe tip and body and a pull strength of 330 N (75 lbf) for enhanced cable security.

Compatibility & Integration

This probe is part of the Bently Nevada 3300 XL system and is designed for use with 3300 XL extension cables and Proximitor sensors. The miniature coaxial ClickLoc connector provides a secure, quick-connection interface. The standard system (5 or 1 meter) offers an Incremental Scale Factor of 7.87 V/mm ± 5% including interchangeability error. For 9 meter systems, the ISF is ± 6.5%. Extended temperature range versions maintain ± 6.5% accuracy over -52°C to +218°C probe tip range.

Selection Guide & Purchasing Advice

When selecting a replacement or spare probe, confirm the required thread size (3/8-24 UNF), overall case length (6.1 in), and total cable length (1.5 meter). The 330101-00-61-15-02-CN is a standard configuration without armor. For applications requiring additional cable protection, consider armored options.

Troubleshooting & Common Issues

• No Output Signal: Check the ClickLoc connector for secure mating and inspect the cable for breaks. Verify the Proximitor sensor is powered and within the 305 m cable length limit.
• Erratic Readings: Ensure the probe tip is not contacting the target. Confirm the target material is within the specified linear range (0.25 to 2.3 mm). Check for excessive cable movement or electromagnetic interference.
• Incorrect Scale Factor: Verify the system length (1.5 m probe + extension cable) matches the Proximitor calibration. The standard ISF is 7.87 V/mm ± 5% for 5 or 1 meter systems at 0°C to +45°C.
• Temperature Drift: If operating outside the standard range (-52°C to +177°C), consider the extended temperature range probe option (up to +218°C probe tip).
