Bently Nevada 330104-00-10-10-02-CN 3300 XL 8 mm Proximity Probe

The Bently Nevada 330104-00-10-10-02-CN is a 3300 XL 8 mm proximity probe used as part of a non-contact eddy current transducer system for shaft vibration, axial position, speed, and phase reference measurements. This configuration combines a 100 mm probe body, 1.0 m integral cable, armored construction, and a ClickLoc connector, making it suitable for machinery protection and condition monitoring systems that require API 670-compliant proximity measurement.

Model Configuration

The ordering code identifies several mechanical and connection characteristics that are important when selecting replacement probes and matching system components.

• 330104: 3300 XL 8 mm Proximity Probe

• 00: 0 mm unthreaded length

• 10: 100 mm probe case length

• 10: 1.0 m (3.3 ft) integral cable length

• 02-CN: Armored version with miniature coaxial ClickLoc connector and CN suffix designation

Correct probe configuration is important because mechanical dimensions and cable lengths affect installation compatibility within a complete 3300 XL transducer system.

Measurement Function

The probe operates on the eddy current principle and measures the distance between the probe tip and a conductive target surface without physical contact. In rotating machinery applications, the signal is commonly used for:

• Radial shaft vibration measurement

• Axial position (thrust) monitoring

• Differential expansion measurement

• Speed measurement

• Keyphasor phase reference applications

These measurements provide dynamic shaft information for machinery protection and condition monitoring systems.

Electrical Performance

The 3300 XL 8 mm transducer system provides a linear measurement range of 2 mm (80 mils). Within the calibrated range, the system delivers a scale factor of 7.87 V/mm (200 mV/mil), enabling accurate displacement measurements when used with the corresponding extension cable and Proximitor sensor.

The specified frequency response extends from 0 Hz to 10 kHz, allowing both static position measurements and dynamic vibration signals to be monitored through the same sensing technology.

Environmental and Compliance Characteristics

Standard 3300 XL 8 mm probes are rated for operation from -52 deg C to +177 deg C. This temperature capability supports installation near bearings, seals, and other machinery locations where elevated temperatures may be present.

The 3300 XL transducer system is designed to meet API 670 requirements and is suitable for use in functional safety architectures supporting SIL 2 and SIL 3 applications when implemented within approved system configurations.

Technical Specifications

Application Considerations

The probe is only one element of a complete 3300 XL transducer system. System performance specifications are achieved when the probe is matched with the appropriate extension cable and Proximitor sensor specified for the 3300 XL platform.

When replacing an existing probe, the full ordering code should be verified to ensure identical probe length, cable length, connector style, and mechanical construction.

Frequently Asked Questions

Q: What does the 02-CN suffix indicate on this probe?
A: The 02-CN configuration identifies an armored probe version equipped with a miniature coaxial ClickLoc connector. The CN suffix is a designated ordering suffix associated with this probe configuration.

Q: Can this probe be used by itself for vibration monitoring?
A: No. The probe is intended to operate as part of a complete 3300 XL transducer system that includes the matching extension cable and Proximitor sensor.

Q: What measurements can this probe support?
A: Depending on system configuration, it can be used for shaft vibration, axial position, differential expansion, rotational speed measurement, and Keyphasor phase reference applications.
