Product Description

The Bently Nevada 3300 XL 8mm Proximity Probe (330101-37-57-10-02-05) is a high-precision, non-contact displacement and vibration transducer engineered for monitoring critical machinery in industrial environments. Part of the 3300 XL Eddy Current Proximity System, this probe is widely used for radial vibration, shaft position, and phase reference (Keyphasor) measurements in turbines, compressors, and high-speed rotating equipment.

This model features a threadless 8mm diameter housing for internal mounting within bearing housings or specialized bracket assemblies. Its 3.7-inch unthreaded length and 5.7-inch overall case provide deep-set measurement capability while maintaining sub-micron accuracy and mechanical stability.

Application Context

The 330101-37-57-10-02-05 probe is ideal for large turbines, centrifugal compressors, and industrial motors, particularly where deep-set bearing housings require precise, non-contact monitoring. Its 1-meter cable is typically combined with 3300 XL extension cables and a Proximitor sensor, forming a total system length of 5 or 9 meters to ensure accurate calibration.

This probe’s unthreaded design allows for fine positional adjustment, making it suitable for axial (thrust) or radial vibration monitoring in harsh operating conditions.


Technical FAQ

How does the ClickLoc connector improve reliability?
The ClickLoc connector locks securely to prevent accidental disconnection due to machine vibration. It features moisture-resistant seals and gold-plated contacts for low-impedance, corrosion-resistant connections.

Can this probe measure thrust (axial) position?
Yes. Its linear measurement range and high stability allow precise monitoring of axial shaft movement, providing early warning of potential bearing or rotor issues.
