Description

The Bently Nevada 330101-00-12-10-02-CN is a high-performance 3300 XL 8 mm proximity probe designed for use in eddy current proximity transducer systems. This non-contacting sensor is engineered to measure both static and dynamic shaft parameters, including radial vibration, axial position, and speed, on critical rotating machinery such as steam and gas turbines, compressors, pumps, and large motors.

The 3300 XL 8 mm system is designed for full backward compatibility and interchangeability with other 3300 series 5 mm and 8 mm transducer components. This design eliminates the need for individual component matching or bench calibration, simplifying maintenance and replacement procedures in the field.

Features

• Non-Contacting Measurement: Provides reliable data on shaft position and vibration without mechanical wear.
• System Interchangeability: Fully compatible with 3300 XL Proximitor sensors and extension cables without requiring system-wide recalibration.
• Robust Design: 3/8-24 UNF thread with a 1.2-inch case length, suitable for standard industrial mounting configurations.
• Regional Compliance: The -CN suffix indicates specific certification compliance for projects located in China.

Applications

• Turbines: Monitoring shaft vibration and axial thrust in gas and steam turbines.
• Compressors: Tracking internal shaft movement and dynamic vibration for centrifugal and axial compressors.
• Motors and Generators: Assessing bearing health and shaft stability.
• Pumps: Measuring shaft position and dynamic vibration in high-energy pumping systems.
• Gearboxes: Monitoring internal shaft movement for wear detection.

Installation Guidelines

• Handling: Proximity probes are precision instruments. Avoid impacts to the probe tip, as damage to the ceramic or coil assembly will affect measurement accuracy.
• Mounting: Ensure the probe is mounted in a rigid bracket to prevent mechanical resonance. Use the provided lock nuts to secure the probe at the required gap distance.
• Cable Routing: Route coaxial cables away from high-voltage lines and sources of electromagnetic interference (EMI). Use protective conduit where mechanical protection is required.
• Grounding: Ensure the Proximitor sensor and the probe installation follow the standard Bently Nevada grounding practices to prevent ground loops.
• System Power: Always disconnect power to the Proximitor sensor before connecting or disconnecting the probe cable to prevent potential electrical damage.

FAQ

What is the primary function of this probe?

It is a non-contacting sensor used in a Proximity Transducer System to measure both static (position) and dynamic (vibration) values by detecting the distance between the probe tip and a conductive surface, such as a machine shaft.

Is this probe interchangeable with other 3300 XL components?

Yes. Probes, extension cables, and Proximitor sensors within the 3300 XL 8 mm system are fully interchangeable without needing individual bench calibration.

Does this model come with armor?

No. The 330101 base model is designated as without armor. It is intended for installations where the cable is routed through a protective conduit.
