Hardware Specifications

Cross-Talk Suppression and Signal Integrity

The 3300 XL system requires precise impedance matching to maintain accuracy in rotor dynamics monitoring. The 330173 cable assembly is constructed to ensure minimal signal attenuation over the specified length. Proper installation requires verification of the total system length to match the calibration requirements of the Proximitor sensor. In environments with high electromagnetic interference, the cable shield must be grounded at the monitor end to prevent noise injection and ensure effective cross-talk suppression between adjacent sensor channels.

Field Installation Guidelines

• Connection Integrity: Ensure all ClickLoc connectors are fully seated and hand-tightened. Do not use tools, as over-tightening can compromise the connector seal or internal contact pins.

• Bend Radius: Adhere to a minimum static bend radius of 25 mm. Exceeding this limit will cause changes to cable impedance and degrade the measurement signal.

• Shielding: The cable shield must be continuous. Avoid clamping the cable in areas with high vibration that could induce fretting corrosion on the shield or center conductor.

• Routing: Route signal cables away from AC power lines and high-current motor leads to prevent induced noise on the vibration signal.

Frequently Asked Questions

• Q: Can this cable be shortened in the field?

  A: No. The 3300 XL system is impedance-matched. Trimming or splicing the cable will alter the system scaling and cause measurement errors.

• Q: Is this cable compatible with 3300 series (non-XL) probes?

  A: No. The 3300 XL system requires specific impedance matching and connector types incompatible with legacy 3300 series hardware.

• Q: What is the maximum total system length allowed?

  A: The system is calibrated for a total length of 5 meters or 9 meters. Ensure the cable configuration aligns with the Proximitor sensor's calibrated length.

• Q: Why is the connector protector used?

  A: It provides environmental sealing and prevents the connection from loosening due to machine vibration, ensuring a stable electrical path.

• Q: Does this cable carry DC voltage?

  A: Yes, it transmits the DC bias voltage and the high-frequency AC carrier signal required for eddy-current proximity sensing.

• Q: How do I test the cable for continuity?

  A: Use a high-impedance ohmmeter to check the center conductor and the shield. Ensure there is no short-circuit between the two.

• Q: Can I use this cable in sub-zero environments?

  A: Yes, the cable materials are rated for operation down to -51 deg C. Avoid manipulating the cable at these temperatures to prevent jacket cracking.

• Q: What does the 'CN' suffix indicate?

  A: The 'CN' suffix designates compliance with specific regional agency approval standards for hardware installation.
