Configured for shaft displacement measurement in 3300 NSv Proximity Transducer Systems, the Bently Nevada 330910-10-22-10-01-CN (330910-10-22-10-01-CN 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.

Suffix Breakdown & Model Matrix

The 330910-10-22-10-01-CN part number defines the specific probe tip diameter, case thread length, and connector configuration. The "10" prefix denotes the probe physical geometry, while the following segments delineate the cable length, connector type, and regional compliance 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 serves 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

• 330910-10-22-10-01-CN Proximity Probe unit.

• Standard regulatory and technical 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.

• Use provided jam nuts to secure the probe at the specified gap distance.

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

• 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 after 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.

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

  A: Grounding the probe 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 signal carrier frequency generated by the Proximitor.

• Q: Is the cable length field-adjustable?

  A: No, the cable length is an integral part of the system impedance and cannot be modified.

• Q: What is the significance of the 10-22-10-01-CN suffix?

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

• Q: Can this probe survive high-pressure environments?

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

• Q: How does temperature affect the probe?

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

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

  A: The 330910 NSv probe must be paired with an NSv-compatible Proximitor to ensure correct impedance matching.
