Hardware Specifications

Mechanical Monitoring and TSI Integration

The 3300 XL system relies on precise eddy-current probe scaling to convert target displacement into a proportional voltage signal. Operators must ensure gap voltage validation, targeting a -10 VDC setpoint to maintain linearity within the transducer's 2 mm range. Rotor dynamics analysis, specifically orbital vibration and shaft centerline monitoring, depends on the phase-coherent signal transmission through the extension cable to the Proximitor sensor. Cross-talk suppression is achieved by observing strict conduit routing standards to prevent interference on the high-frequency carrier wave.

Field Installation Guidelines

• Routing: Install within dedicated electrical conduit. Maintain separation from high-voltage lines to minimize electromagnetic noise injection into the coaxial path.

• Bend Radius: Maintain a minimum bend radius of 25 mm. Sharp bends deform the internal coaxial dielectric and alter signal impedance.

• Connector Integrity: Tighten connectors to manufacturer specifications. Use the supplied connector protector to ensure an environmental seal against moisture and oil.

• Grounding: Maintain shield continuity from the probe to the monitor. Do not create ground loops by grounding the shield at multiple points.

Frequently Asked Questions

• Can this cable be trimmed to match a specific installation length?

  No. The system is factory-calibrated for specific total lengths. Altering the cable length changes the phase and impedance, leading to measurement inaccuracy.

• What is the consequence of high-frequency interference?

  Interference manifests as spurious vibration data and baseline drift. Use dedicated conduit and proper shielding to maintain signal-to-noise ratio.

• Is this cable compatible with 3300 series Proximitor sensors?

  It is optimized for 3300 XL systems; impedance mismatches with legacy 3300 series components will degrade measurement linearity.

• How do I verify a successful installation?

  Perform a gap voltage check at the monitor rack; the reading should match the factory calibration curve for the specific probe and cable combination.

• Why is 75 ohm impedance specified?

  The 3300 XL architecture is matched to 75 ohm to ensure maximum fidelity and minimal signal reflection of the high-frequency carrier wave.

• Does the cable require specific environmental protection?

  While rated for harsh environments, use external conduit for physical protection and ensure all connector protectors are fully seated.

• How should I test for continuity?

  Use a high-impedance multimeter to verify the center conductor and outer shield continuity; ensure no shorts exist between the conductor and shield.

• Can the cable be used in vacuum environments?

  Yes, the materials are rated for high-temperature and vacuum applications, provided the assembly is properly installed and sealed.
