Configured for non-contact displacement measurement in 3300 XL transducer systems, the Bently Nevada 330910-014-19-10-02-00 (330910-014-19-10-02-00 Proximity Probe) provides direct physical signal execution for shaft position and vibration monitoring platforms.

Physical Identification & Configuration

The 330910-014-19-10-02-00 functions as an 8 mm eddy-current probe. It is designed to interface with the 3300 XL Proximitor sensor, providing a linear voltage output proportional to the gap distance between the probe tip and the observed ferromagnetic target.

Hardware Specifications

Eddy-Current Probe Scaling & Rotor Dynamics

System accuracy is dependent on maintaining consistent eddy-current probe scaling. The transducer output must be validated against a standard target material to ensure the millivolt-per-mil (mV/mil) conversion ratio remains within documented linearity specifications. Proper gap voltage validation is performed by ensuring the static output rests at the -10 VDC target when set at the middle of the linear operating range. Furthermore, cross-talk suppression requires that adjacent probes observing the same rotor be spaced according to the manufacturer’s minimum distance requirements to prevent high-frequency interference within the inductive field.

Field Installation Guidelines

• Mounting: Ensure the probe is mounted in a rigid bracket to prevent mechanical vibration from introducing false displacement signals.

• Gap Adjustment: Thread the probe to the specified gap distance; verify the gap voltage using a digital multimeter at the Proximitor output terminals.

• Shielding: Route the probe coaxial cable through grounded conduit and ensure the connector remains free from moisture or contaminants to prevent signal drift.

• Alignment: Confirm the probe tip is centered over the target surface to avoid non-linear output response caused by edge effects.

Frequently Asked Questions

• What is the probe's primary frequency response?

  The probe system provides a frequency response from DC to 10 kHz, capturing both static shaft position and dynamic vibration signals.

• Is the probe tip material replaceable?

  The tip is an integral part of the probe assembly; damage to the tip or cable necessitates replacement of the entire probe unit.

• What defines a "Not OK" signal?

  A "Not OK" condition occurs if the probe cable is open or shorted, or if the bias voltage deviates outside the operating window of the Proximitor.

• Can this probe be used in high-pressure environments?

  The probe body is pressure-rated for the specific application; consult technical documentation to verify compatibility with the expected vessel pressure.

• Does cable length affect calibration?

  Yes, the system is calibrated as a matched set (Probe, Cable, Proximitor); changing the total cable length will invalidate the system calibration.

• How is the probe protected from ground loops?

  The probe tip is electrically isolated from the sensor housing, and the cable shield is terminated at the Proximitor to minimize ground loop pathways.

• Is the probe polarity sensitive?

  The proximity system output is a negative voltage proportional to gap distance; observe correct wiring polarity at the Proximitor terminal block.

• How often should probe alignment be checked?

  Alignment should be verified during scheduled maintenance cycles or if system vibration readings exhibit unexplained deviations or instability.
