Bently Nevada 330101-00-11-10-02-CN 3300 XL 8 mm Probe

Technical Specifications Breakdown

Key parameters for the 330101-00-11-10-02-CN are listed below for quick reference:

Industry Applications: Preventing Catastrophic Failures

Turbomachinery Protection

In steam turbines and centrifugal compressors, shaft vibration must be monitored continuously. The 330101-00-11-10-02-CN offers a linear range of 2 mm (80 mils) starting at 0.25 mm (10 mils) from the target, enabling early detection of imbalance or misalignment. Its 7.87 V/mm (200 mV/mil) scale factor provides high-resolution data for trend analysis.

Pump and Motor Condition Monitoring

For large industrial pumps and electric motors, the probe’s robust PPS tip and stainless steel case withstand harsh conditions. The standard probe operates from -52°C to +177°C, making it suitable for hot environments near bearings. The optional FluidLoc cable prevents oil wicking, a common issue in lubricated machinery.

Installation & Setup Guidance

Proper gap setting is critical for accurate readings. Bently Nevada recommends a gap setting of -9 Vdc for radial vibration, which corresponds to approximately 1.27 mm (50 mils). Use the recommended field wiring: 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 Proximitor Sensor and the monitor. Ensure the probe tip is clean and free of debris before installation.

Maintenance & Reliability

Inspect the probe and cable periodically for physical damage, especially in high-vibration or high-temperature areas. The probe is designed to seal differential pressure between the tip and case using a Viton® O-ring. Avoid exposing the probe to temperatures below -34°C (-30°F) to prevent premature failure of the pressure seal. For applications requiring pressure seal testing, contact the custom design department.

Robust Vibration Monitoring for Critical Machinery

When unplanned downtime threatens production targets, the Bently Nevada 330101-00-11-10-02-CN provides the reliable shaft vibration data needed for predictive maintenance. This 3300 XL 8 mm probe, with a 3/8-24 UNF thread and without armor, is engineered for harsh industrial environments where accuracy and durability are non-negotiable.

The 330101-00-11-10-02-CN features a patented TipLoc molding method that creates a stronger bond between the probe tip and body, reducing the risk of sensor failure. Its CableLoc design provides 330 N (75 lbf) pull strength, ensuring the cable remains securely attached even under mechanical stress. For applications where oil leakage through the cable interior is a concern, an optional FluidLoc cable option is available.

Compatibility & Integration

The 330101-00-11-10-02-CN is part of the 3300 XL system and is compatible with 3300 XL extension cables and Proximitor Sensors. The miniature coaxial ClickLoc connector ensures a secure, quick connection. For extended temperature range applications, use the ETR probe version which operates from -52°C to +218°C for the tip and -51°C to +260°C for the cable and connector.

Selection Guide & Purchasing Advice

When selecting a probe, consider the thread type, cable length, and environmental conditions. For armored or longer cable needs, explore other options in the 3300 XL series. Contact AutoDCSTech for current pricing and lifecycle status before ordering.
