Bently Nevada 330703-010-060-10-01-CN 3300 XL 11 mm Proximity Probe

Product Overview

Bently Nevada 330703-010-060-10-01-CN is a 3300 XL 11 mm proximity probe designed for shaft vibration and position monitoring in turbines, compressors, generators, and heavy industrial rotating machinery. It operates as part of the Bently Nevada 3300 XL eddy-current measurement system and delivers stable displacement signals under high vibration and electrical noise conditions.

This probe configuration is used in medium to heavy-duty machinery where larger target surfaces and higher sensitivity are required compared to standard 8 mm probes. The M14 x 1.5 threaded body ensures secure mechanical mounting in industrial housings with consistent alignment under continuous vibration.

The CN approval option supports region-specific compliance requirements while maintaining full compatibility with global 3300 XL monitoring systems used in critical asset protection.

Configuration Breakdown

Each segment defines mechanical geometry, cable length, connector type, and compliance classification within the 3300 XL probe system architecture.

Technical Specifications

Engineering Interpretation Notes

The 11 mm probe design increases sensitivity and measurement range for larger shaft diameters and heavy-duty rotating equipment. It improves signal stability in environments with higher mechanical vibration amplitude.

The M14 threaded interface provides strong mechanical fixation, reducing installation drift in long-term continuous operation.

Extended case geometry improves mounting flexibility in deeper machine housings where standard probe lengths are insufficient.

Field Application Notes

Where is this probe used?
It is used in turbines, compressors, and large industrial rotating machines requiring higher sensitivity measurement.

Is it compatible with 8 mm systems?
No. 11 mm probes require matched system configuration for correct calibration and scaling.

What is the benefit of 11 mm design?
It provides improved sensitivity and stability for larger shaft applications.

Does CN version affect performance?
No. CN refers only to approval compliance, not electrical characteristics.

Installation & Commissioning Notes

Ensure correct probe gap setting during installation to maintain linear output response in the eddy-current system.

Use torque-controlled tightening on M14 thread to prevent misalignment under vibration conditions.

Maintain separation from high-voltage cables to reduce electromagnetic interference in signal transmission.

Verify connector engagement fully during installation to avoid intermittent signal loss.

Engineering & Operational Guidance

Avoid over-tightening during installation as it may affect probe alignment accuracy.

Maintain clean mounting surfaces to ensure stable mechanical coupling and consistent measurement output.

Route probe cables away from VFD output wiring and high-current conductors to minimize EMI influence.

Inspect installation after initial thermal cycling to confirm mechanical stability under operating conditions.
