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

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.
