The Bently Nevada 330103-00-10-10-12-05 is a high-performance 3300 XL 8 mm proximity probe designed for non-contacting vibration and position monitoring in industrial rotating machinery. This transducer system provides an output voltage proportional to the gap between the probe tip and a conductive target, enabling precise measurement of both static position and dynamic vibration.

Features

• Advanced eddy current transducer technology for high-accuracy displacement monitoring.
• Patented TipLoc molding for a robust bond between the probe tip and body.
• CableLoc design providing 330 N (75 lbf) pull strength for enhanced cable security.
• FluidLoc cable option to prevent liquid leakage through the cable interior.
• Full electrical and mechanical interchangeability with other 3300 XL series components.
• Compliant with API 670 standards for mechanical configuration, linear range, and accuracy.

Applications

• Fluid-film bearing machines
• Centrifugal and process gas compressors
• Turbo expanders
• High-speed electric motors and generators
• Centrifugal pumps and industrial fans
• Keyphasor reference and speed measurement systems

Technical Specifications

Installation Guidelines

• Hole Preparation: Use a 0.332-inch drill and a Q-size tap drill for the 3/8-24 UNF threads.
• Mounting: Ensure thread engagement does not exceed 0.562 inches to prevent the probe tip from bottoming out against the target.
• Gapping: For standard AISI 4140 steel targets, set the gap to 1.27 mm (50 mils) to achieve the center of the linear range (-9 Vdc).
• Torque: Apply a maximum tightening torque of 11.3 N·m (100 in·lb) to the probe case.
• Handling: Always power down the system before disconnecting or installing probes to prevent electrical damage. Use ESD-safe practices when handling the connector.

FAQ

What is the 330103-00-10-10-12-05?

It is a specific configuration of the Bently Nevada 3300 XL 8 mm proximity probe used for non-contacting vibration and displacement measurement in industrial machinery.

What is the ideal gap voltage for this probe?

The ideal gap voltage is -9.0 VDC, corresponding to a 1.27 mm (50 mils) gap. The linear operating range is typically between -1.0 VDC and -17.0 VDC.

Is this probe interchangeable with older models?

Yes, the 3300 XL series is designed to be electrically and mechanically interchangeable with previous 3300 8 mm systems, though using 3300 XL probes with 3300 XL Proximitor sensors is recommended for optimal performance.
