Product Overview

The 330103-00-13-05-02-05 is a high-precision 8mm proximity transducer from the Bently Nevada 3300 XL series, specifically configured for non-contacting displacement and vibration measurements. This sensor utilizes eddy current technology to track the position of rotating shafts in critical machinery such as turbines and high-speed compressors. Designed with a focus on streamlined mechanical integration, this model features a 130mm overall case length and a short-reach 0.5-meter lead. It serves as a fundamental component for Turbine Supervisory Instrumentation (TSI), providing the high-fidelity data required for predictive maintenance and machine protection systems.

Industrial Deployment and Operational Roles

Radial Vibration Monitoring

In centrifugal pumps and motors, this probe measures the dynamic motion of the shaft relative to the bearing housing. By providing real-time vibration data, it allows operators to detect early signs of imbalance, misalignment, or bearing degradation.

Axial Thrust Position Detection

The 330103-00-13-05-02-05 is frequently used to monitor the longitudinal (axial) movement of a shaft. This is vital in preventing catastrophic contact between rotating and stationary components within a turbine casing.

Condition-Based Maintenance

By integrating this sensor into a 3500 Monitoring System, plants can transition from reactive repairs to a data-driven maintenance schedule. The high sensitivity of the 8mm tip ensures that even sub-micron changes in shaft position are recorded.

Space-Constrained Installations

The 0.5-meter lead length is specifically chosen for applications where the junction box or Proximitor sensor is mounted in immediate proximity to the probe installation point. This reduces excess cable management and minimizes potential signal interference in high-density machinery decks.

FAQ

Q: Does this model carry ATEX or CSA hazardous area certifications?

A: No. The "00" option in the 330103-00-13-05-02-05 part number indicates the standard version without specific third-party hazardous location approvals. It is intended for general industrial use.

Q: Is the 0.5-meter cable enough for a standard 3300 XL installation?

A: This probe acts as a "probe lead." To reach a Proximitor sensor, it must be connected to a 3300 XL extension cable. You must ensure the combined length of this lead and the extension cable matches the calibration of your Proximitor (typically 5.0m or 9.0m total).

Q: Can this probe be used to measure shaft speed?

A: Yes. When positioned to observe a notch or keyway on a rotating shaft, this probe functions as a Keyphasor or tachometer sensor, providing precise RPM and phase reference data.

Q: What is the benefit of the ClickLoc connector system?

A: The ClickLoc system provides a secure, positive-locking connection that prevents the probe from disconnecting due to machine vibration. The gold plating ensures high conductivity and resists corrosion.

Q: Is it necessary to calibrate the probe to the extension cable?

A: No. The 3300 XL 8mm series features complete interchangeability. Any 3300 XL probe can be paired with any 3300 XL extension cable and Proximitor without manual bench calibration, provided the total system length is correct.
