Configured for high-frequency signal transmission in 3300 XL monitoring systems, the Bently Nevada 330130-080-00-00 (330130-080-00-00 Extension Cable) provides direct physical electrical continuity between the proximity probe and the Proximitor sensor.

Model Suffix Decomposition

The 330130-080-00-00 part number indicates the following hardware configuration:

• 330130: 3300 XL Extension Cable assembly.

• 080: 8.0 meters total system length requirement.

• 00: Standard connector type without protective housing options.

• 00: Standard agency approval configuration.

Technical Hardware Specifications

Rotor Dynamics and Impedance Matching

The 3300 XL system performance is predicated on maintaining a precise 75 Ohm impedance path across the entire probe-cable-Proximitor loop. The 330130-080-00-00 cable is calibrated to compensate for signal attenuation and phase shift over its length. Eddy-current probe scaling is sensitive to the total length of the coaxial run; thus, the system must be calibrated as a matched set. Cross-talk suppression is achieved through the use of high-quality internal shielding, which must remain intact to prevent inductive interference from surrounding high-voltage conduits or motor leads.

Field Installation Protocols

• Mechanical Securing: Utilize cable ties or clamps at 500 mm intervals to prevent cable whipping, which causes mechanical stress at the connector interface.

• Bend Radius: Adhere to a minimum static bend radius of 25 mm. Exceeding this will cause permanent deformation of the dielectric, altering signal impedance.

• Connector Care: Inspect the ClickLoc contacts for debris or moisture prior to mating. Ensure the connection is fully latched to maintain environmental sealing.

• Shield Continuity: Do not ground the cable shield at both ends if ground potential differences exist between the probe mount and the monitor rack, as this induces ground loops.

Technical Inquiry Clarifications

• Q: Can I use this cable with a 5-meter system?

  A: No. The 330130-080-00-00 is impedance-matched for an 8-meter system. Mixing lengths will invalidate the system linearity and monitoring accuracy.

• Q: What is the purpose of the ClickLoc connector?

  A: It provides a secure, repeatable electrical contact that maintains 75 Ohm impedance and prevents accidental disconnection due to machine-induced vibration.

• Q: Is this cable repairable?

  A: No. Repairing or splicing the coaxial cable introduces impedance discontinuities, which manifest as signal noise or gain errors.

• Q: How do I measure the cable for a short circuit?

  A: Disconnect both ends and use an ohmmeter to verify infinite resistance between the center conductor and the shield.

• Q: Can this be used in high-temperature zones?

  A: The cable is rated for up to 177 deg C. Ensure the cable is not in direct contact with hot exhaust piping or steam lines that exceed this limit.

• Q: Does this cable require shielding from EMI?

  A: While the cable is shielded, it should be routed through metallic conduit when passing near variable frequency drives or high-power switching equipment.

• Q: Can the cable be pulled through conduit with force?

  A: No. Excessive pulling force will stretch the center conductor or compress the dielectric, resulting in impedance degradation.

• Q: Why is the weight 0.42 kg?

  A: The weight reflects the total mass of the 8-meter cable, the protective jacket, and the heavy-duty ClickLoc connector assemblies.
