Hardware Specifications

Mechanical Monitoring and TSI Integration

The 3300 XL system relies on precise eddy-current probe scaling to ensure linear output relative to target displacement. Proper installation requires gap voltage validation, where the target operational gap typically centers on a -10 VDC setpoint to maintain linearity within the transducer's 2 mm range. Rotor dynamics analysis, such as shaft centerline and orbital vibration monitoring, depends on the phase-coherent signal transmission through the extension cable and Proximitor sensor. Cross-talk suppression is maintained through high-frequency shielding, preventing interference when multiple cables are installed in close proximity on the same machine casing.

Field Installation Guidelines

• Routing: Install within dedicated electrical conduit to protect the coaxial cable from physical damage and electromagnetic interference.

• Bending Radius: Adhere to a minimum bend radius of 25 mm. Sharp bends can permanently deform the coaxial dielectric and alter signal impedance.

• Connections: Tighten connectors firmly; ensure the connector protector is fully engaged to prevent moisture and oil ingress.

• Shielding: Maintain continuous shielding from probe to monitor. Do not create multiple grounds, as this introduces ground loops that degrade vibration data quality.

Frequently Asked Questions

• Can this cable be used with non-XL 3300 series components?

  No. This cable is specifically engineered for the 3300 XL system; impedance mismatches with older 3300 series components will cause signal distortion.

• What is the consequence of cable length mismatch?

  The system is factory-calibrated for a specific total length. A mismatch alters the phase and frequency response, necessitating system re-calibration.

• Does the cable have internal armor?

  The 00 suffix denotes standard construction without internal armor; for harsh environments, use external rigid or flexible conduit.

• Can I splice this cable?

  No. Splicing introduces impedance discontinuities and significantly degrades high-frequency signal integrity. Replace the cable if damaged.

• What does the 05 suffix indicate?

  The 05 indicates the connector includes a factory-installed protector, essential for maintaining signal integrity in oily or humid environments.

• Is the cable compatible with vacuum applications?

  Yes, the materials are rated for vacuum environments, provided the assembly is properly installed and the connectors are sealed.

• How do I test the cable for continuity?

  Use a multimeter to measure the resistance of the center conductor and ensure there is no short to the outer shield.

• Why is 75 ohm impedance specified?

  The system is calibrated for 75 ohm coaxial cable to ensure optimal matching of the high-frequency carrier wave generated by the Proximitor.
