330101-00-12-10-12-CN | Bently Nevada 3300 XL 8 mm Probe

Introduction to the Bently Nevada 330101-00-12-10-12-CN

When machine vibration threatens uptime, the 330101-00-12-10-12-CN delivers precise, dependable measurement. As part of the Bently Nevada 3300 XL family, this 8 mm probe is engineered for industrial rotating machinery monitoring. Its robust design helps you detect shaft vibration and position changes early, reducing unplanned downtime.

The probe features a 3/8-24 UNF thread, making it compatible with standard mounting hardware. With a total length of 1.0 meter (3.3 feet), it suits many installation layouts. The miniature coaxial ClickLoc connector ensures secure signal transmission, while the FluidLoc cable option prevents oil leakage through the cable interior.

This model is manufactured in the U.S.A. and carries country-specific agency approvals, as indicated by the CN option. Whether you are upgrading an existing system or specifying new equipment, the 330101-00-12-10-12-CN offers the performance and durability you need.

Key Features and Technical Specifications

• Probe type: 3300 XL 8 mm probe with 3/8-24 UNF thread, without armor.
• Unthreaded length: 0.0 inches (option 00).
• Overall case length: 1.2 inches (option 12).
• Total length: 1.0 meter (3.3 feet) (option 10).
• Connector: Miniature coaxial ClickLoc connector (option 12).
• Cable type: FluidLoc cable, designed to prevent liquid leakage.
• Agency approval: Country-specific approvals (option CN).

The patented TipLoc molding method creates a robust bond between the probe tip and body. The CableLoc design provides 330 N (75 lbf) pull strength, securing the cable and tip. The 8 mm probe offers thicker encapsulation of the coil in molded PPS plastic, resulting in a more rugged probe that withstands physical abuse.

Performance and Reliability

The 330101-00-12-10-12-CN delivers a linear range of 2 mm (80 mils), starting at approximately 0.25 mm (10 mils) from the target. The recommended gap setting for radial vibration is -9 Vdc, approximately 1.27 mm (50 mils). The incremental scale factor is 7.87 V/mm (200 mV/mil) ±5% for standard 1-meter systems, measured over the linear range from 0°C to +45°C.

Deviation from best fit straight line is less than ±0.025 mm (±1 mil) for standard 1-meter systems, ensuring accurate readings. The probe operates in temperatures from -52°C to +177°C, with an extended temperature range option available for higher heat environments. The probe case is made of AISI 303 or 304 stainless steel, and the probe tip is molded PPS plastic.

Applications and Use Cases

This probe is ideal for vibration monitoring on pumps, motors, compressors, and turbines. In these applications, reliable shaft displacement data is critical for predictive maintenance. The 330101-00-12-10-12-CN helps you identify misalignment, unbalance, and bearing wear before they cause failure.

Its rugged construction makes it suitable for harsh industrial environments where physical abuse or liquid exposure is a concern. The FluidLoc cable option is particularly valuable in oil-lubricated machinery, preventing leaks that could contaminate the process. By integrating this probe into your condition monitoring system, you can improve asset reliability and extend equipment life.

Installation and Setup

Proper installation is essential for accurate measurements. Mount the probe with the 3/8-24 UNF thread into a suitable mounting hole, ensuring the tip is positioned within the linear range. For radial vibration, set the gap to approximately -9 Vdc, which corresponds to about 1.27 mm (50 mils). Use the recommended field wiring of 0.2 to 1.5 mm² (16 to 24 AWG) with a shielded triad cable. Keep the cable length between the probe and monitor within 305 meters (1,000 feet) to avoid signal degradation.

Always follow the manufacturer's installation manual for detailed torque and mounting specifications. If you need assistance, contact Petro Auto Tech for guidance.

Maintenance and Reliability

Regular inspection of the probe and cable is recommended to ensure reliable operation. Check the probe tip for damage or wear, and verify that the connector is secure. The probe is designed to seal differential pressure between the tip and case, using a Viton O-ring. Although not pressure tested prior to shipment, you can request a pressure seal test from the custom design department if required.

The probe's relative humidity performance shows less than a 3% change in Average Scale Factor when tested in 93% humidity per IEC 68-2-3 for up to 56 days. This stability makes it suitable for humid environments. By following a routine maintenance schedule, you can maximize the probe's service life and measurement accuracy.

Compatibility and Integration

The 330101-00-12-10-12-CN is designed to work with Bently Nevada 3300 XL Proximitor sensors and monitoring systems. The miniature coaxial ClickLoc connector ensures a secure and reliable connection. The probe's output is compatible with standard vibration monitoring equipment that accepts eddy-current probe signals.

For new installations, verify that your monitor supports the probe's scale factor of 7.87 V/mm (200 mV/mil). This ensures accurate displacement readings. The probe's 1.0 meter cable length is suitable for many mounting configurations, and extension cables are available for longer runs.
