Configured for shaft displacement measurement in 3300 XL 8 mm Proximity Transducer Systems, the Bently Nevada 330905-14-19-10-02-05 (330905-14-19-10-02-05 Proximity Probe) provides direct physical signal acquisition for monitoring rotating machinery interfaces. This hardware component translates proximity to metallic surfaces into proportional voltage signals for downstream signal conditioning and analysis.

Part Number Configuration

The 330905-14-19-10-02-05 part number defines the specific probe tip diameter, case thread length, and connector configuration. The "14" and "19" prefixes delineate probe physical geometry and case length, while subsequent segments specify the cable type and agency approval standards. This part number represents a fixed electrical and mechanical assembly; no internal field modifications are supported, as the transducer system requires factory-matched loop impedance.

Hardware Specifications

Bently Nevada TSI Mechanical Monitoring Characteristics

The probe functions as the primary sensor for eddy-current probe scaling within the TSI monitoring loop. It maintains signal path integrity necessary for -10 VDC gap voltage validation at the associated Proximitor. The probe tip utilizes proprietary materials to ensure linearity in proximity measurement, while the internal coil assembly is engineered for cross-talk suppression in high-frequency monitoring applications. By providing a stable frequency-dependent output, the probe enables the monitoring system to calculate precise rotor dynamics, including vibration amplitude and centerline position.

## Ordering info

• 330905-14-19-10-02-05 Proximity Probe unit.

• Standard regulatory and technical compliance documentation.

• Note: Extension cables and Proximitor sensors are supplied as separate components.

Field Installation Guidelines

• Ensure the probe is mounted in a rigid bracket to prevent mechanical resonance during machine operation.

• Secure the probe at the specified gap distance using the provided locking nuts.

• Route the integrated cable through metallic conduit, ensuring the shield is grounded at the Proximitor end only to avoid ground loops.

• Avoid routing cables in proximity to high-current power conductors to prevent signal noise injection.

• Verify the gap voltage using a digital multimeter at the Proximitor terminals post-installation.

Frequently Asked Questions

• Q: Can this probe be calibrated for non-steel targets?

  A: Probe linearity is calibrated for AISI 4140 steel; using other materials requires a specific scaling factor adjustment in the monitor configuration.

• Q: What happens if the probe case is grounded to the machine?

  A: Grounding the case can introduce ground loops; the probe should be mounted using insulated hardware if necessary to maintain a single-point ground.

• Q: Does the probe require an external power supply?

  A: No, the probe is a passive device powered by the carrier frequency generated by the Proximitor sensor.

• Q: Is the cable length field-adjustable?

  A: No, the cable length is an integral part of the system impedance and cannot be modified without affecting calibration.

• Q: What is the significance of the 14-19-10-02-05 suffix?

  A: These digits dictate the specific physical length, mounting thread, and connector type required for the original machine design.

• Q: Can this probe operate in high-pressure fluid environments?

  A: The probe tip is sealed for such environments, but verify the pressure rating of the mounting installation before operation.

• Q: How does temperature affect the probe output?

  A: The probe maintains linear output across the specified temperature range; large thermal gradients can affect mechanical gap distance.

• Q: Is this probe compatible with standard 3300 XL Proximitors?

  A: Yes, this probe is designed for seamless integration with the 3300 XL 8 mm Proximitor sensor.
