The Bently Nevada 330910-14-19-10-02-00, also cataloged as the 330910-14-19-10-02-00 NSv Proximity Probe, operates as a dedicated hardware component for eddy-current displacement measurement within TSI monitoring platforms.

Model Matrix Specifications

The part number 330910-14-19-10-02-00 encodes physical probe configuration, including thread size, total length, and connector termination type specific to the 3300 XL NSv system.

Hardware Specifications

Mechanical Monitoring and Eddy-Current Dynamics

The NSv probe utilizes an 8 MHz carrier frequency, distinct from standard 3300 XL probes, to provide measurement capability for small-target applications. Accurate operation requires validation of the probe gap voltage to ensure the signal remains within the linear dynamic range of the proximitor (nominally centered at -10 VDC). In rotor dynamics applications, maintain at least 4 diameters of clearance between adjacent probes to suppress cross-talk and prevent induced signal bias.

Field Installation Guidelines

• Mechanical Engagement: Ensure thread engagement does not exceed housing depth limits to prevent contact with the shaft target.

• Torque Verification: Apply manufacturer-specified torque to locknuts to prevent vibration-induced movement and maintain reference position.

• Signal Grounding: Maintain continuity of the coaxial shield to the monitoring system common ground at the proximitor terminal only.

• Cable Protection: Use metallic conduit for outdoor or harsh environments; minimize bend radius to prevent internal coax damage.

Frequently Asked Questions

• Q: Does this probe support RS-485 communication?

  A: No. The probe is a passive eddy-current transducer; RS-485 is an interface feature of associated digital monitors, not the probe itself.

• Q: What is the maximum linear range?

  A: The linear range is approximately 2.0 mm; operation outside this range results in non-linear output voltage.

• Q: Is this probe interchangeable with 3300 XL 8mm probes?

  A: No. NSv probes are designed for a different carrier frequency (8 MHz) and require specific NSv proximitors for operation.

• Q: How do I check for a broken cable?

  A: Check for an open circuit using a multimeter on the coax connector. A reading near supply voltage at the monitor indicates a disconnection.

• Q: Can I use this in high-pressure environments?

  A: Ensure the probe is mounted with a suitable pressure seal/bushing if penetrating a pressurized casing to prevent leakage.

• Q: What is the recommended gap setting?

  A: The gap is typically set to 1.27 mm (50 mils) to center the signal within the linear range.

• Q: How does temperature affect the output?

  A: The probe is thermally compensated, but extreme temperature shifts can cause small offsets in the gap voltage reading.

• Q: Can the probe be painted?

  A: No. Paint, epoxy, or any conductive/dielectric coating on the tip alters the probe's inductance and invalidates calibration.
