Description

The Bently Nevada 330130-045-02-00 operates as a dedicated hardware component for high-frequency signal transmission within 3300 XL 8mm Proximity Transducer systems. Consequently, the cable connects the proximity probe directly to the Proximitor Sensor, acting as a critical impedance-matched pathway for eddy-current monitoring signals. This configuration ensures precise data transmission for rotor dynamics analysis and machinery protection systems without introducing signal degradation across the connection loop.

Suffix Breakdown & Model Matrix

The specific alphanumeric configuration of the model number determines the physical length and structural specifications as follows:

• 045 (Cable Length Option): Defines a total cable length of 4.5 meters (14.8 feet).
• 02 (Connector and Cable Option): Features miniature coaxial ClickLoc connectors with standard cable insulation.
• 00 (Agency Approval Option): Indicates no specific hazardous area certifications are required for this component.

Hardware Specifications

System Balancing and Cross-Talk Suppression

Because the transducer system relies on a precise electrical resonance loop, engineers must maintain a total system electrical length of exactly 5.0 meters or 9.0 meters. Therefore, deploying this 4.5-meter extension cable requires combining it exclusively with a 0.5-meter proximity probe to achieve the balanced 5.0-meter system. Furthermore, the high-density internal braided shield delivers robust cross-talk suppression. This shielding actively blocks radio frequency interference (RFI) and stray electromagnetic fields, thereby preventing them from compromising the low-voltage eddy-current signals generated near the machine bearings.

Frequently Asked Questions

• Q: Can this extension cable be cut or spliced in the field to match a specific custom length?
  • A: No. Altering the physical length of the coaxial line modifies its electrical impedance and capacitance. This disruption changes the Proximitor calibration, which leads to severe scale factor errors.
• Q: Is an external tool required to mate the ClickLoc connectors?
  • A: No. The ClickLoc system joins finger-tight. Applying mechanical tools like pliers strips the gold plating and warps the internal spring-loaded pin mechanism.

Field Installation Guidelines

• Minimum Bend Radius: Maintain a physical bend radius of no less than 25.4 mm (1.0 in) during routing to prevent internal kinking or separation of the FEP dielectric core.
• Conduit Protection: Run the extension cable inside dedicated, grounded metal conduit or cable trays to guard against mechanical pinch points and environmental fluids.
• Connector Insulation: Utilize the supplied silicone connector protectors or self-sealing tape over the ClickLoc junction to prevent oil ingress and potential grounding paths at the connection point.
• Terminal Isolation: Avoid routing this low-voltage sensor cable parallel to high-current AC motor leads or switching drive cables to preserve baseline signal integrity.
