Bently Nevada 330102-00-25-10-02-CN 8mm Proximity Probe

Buy the genuine Bently Nevada 330102-00-25-10-02-CN 8mm eddy-current proximity probe. Fully configured with a 3/8-24 UNF thread, 2.5-inch case, 1.0-meter integrated cable, and -CN explosive atmosphere certification pathways. Stocked and ready for express global shipping.

The Bently Nevada 330102-00-25-10-02-CN belongs to the industry-standard 3300 XL 8mm Proximity Transducer System. This eddy-current sensor precisely measures relative shaft displacement, dynamic vibration, and static position (thrust drift) on high-speed rotating assets such as turbines, compressors, and gearboxes.

Hardware Specifications

Scale Factor Sensitivity: 7.87 V/mm (200 mV/mil) when paired with a matching 3300 XL Proximitor Sensor.
Linear Measuring Range: 2.0 mm (80 mils), starting at an approximate gap of 0.25 mm (10 mils).
Connector Integrity: Features a fluid-resistant ClickLoc gold-plated coaxial interface requiring no specialized tools.
EMI/RFI Resilience: Integrated shielding matrix permits open-air mounting or fiberglass enclosure containment without signal deformation from nearby radio bands.

Frequently Asked Questions

Q: Can I use this probe with an older 3300 (Non-XL) series Proximitor sensor? A: Yes. The 3300 XL 8mm probe is physically and electrically backward-compatible with legacy non-XL 3300 5mm and 8mm systems, though performance defaults to the legacy sensor’s parameters.

Q: What is the purpose of the gold ClickLoc connector? A: The ClickLoc connector is designed to prevent loose mechanical links and eliminate connection drift. It resists environmental contamination from lubricating oils and moisture common within bearing housings.

Field Installation Guidelines

Target Gap Zeroing: Use a digital voltmeter connected to the Proximitor’s “Prox” and “Com” terminals to set the mechanical gap. Adjust the probe depth until your multimeter reads approximately -10.0 VDC (the midpoint of the linear range).
Minimum Target Footprint: Ensure the target shaft surface has a diameter at least 3 times greater than the 8mm tip diameter to avoid edge-effect magnetic field truncation.
Avoid Cross-Talk: When running multiple adjacent sensors, maintain a minimum physical distance of 40 mm (1.6 inches) between probe centers to prevent overlapping electromagnetic fields.
