Description

Configured for cross-talk suppression and signal transmission in machinery monitoring systems, the Bently Nevada 330130-080-12-05 (330130 Proximity Extension Cable) provides direct physical/electrical execution. This hardware component connects a 3300 XL 8 mm proximity probe to a 3300 XL Proximitor Sensor, forming a complete eddy-current transducer loop. The cable structure features matched impedance characteristics to eliminate radio frequency attenuation during high-speed rotor dynamics tracking.

Hardware Specifications

Machinery Monitoring and Eddy-Current Probe Scaling

The internal electrical parameters of this extension cable are designed to sustain precise eddy-current probe scaling across the transducer assembly. Maintaining proper loop capacitance is necessary for gap voltage validation (-10 VDC targets), preventing linear displacement scale errors during operational changes. The heavy physical layering resists environmental degradation, while the integrated armor minimizes mechanical deflection. Furthermore, the cable geometry optimizes cross-talk suppression inside crowded wire trays, allowing clean vibration and position signals to reach the diagnostic framework without distortion.

Frequently Asked Questions

Q: How does the stainless steel armor with FEP jacket (Option 12) affect physical installation?

A: The armor provides mechanical defense against crushing, abrasive friction, and sharp bends, while the outer FEP jacket acts as a barrier against moisture and chemical corrosion in extreme environments.

Q: Can this 8.0-meter cable be used with a 5-meter system Proximitor Sensor?

A: No. The total electrical length of the probe and extension cable must match the specific tuning of the Proximitor Sensor (typically 5.0 meters or 9.0 meters total). Using an 8.0-meter cable requires a 9.0-meter Proximitor combined with a 1.0-meter probe to maintain correct eddy-current probe scaling.

Field Installation Guidelines

• Minimum Bend Radius: Do not exceed a minimum bend radius of 25.4 mm (1.0 in) for unarmored cables or 50.8 mm (2.0 in) for this armored variant to prevent structural core distortion.
• Connector Integrity: Clean the ClickLoc coaxial surfaces with a lint-free wipe before joining; ensure they click tightly together to prevent high-resistance contact points.
• Silicone Boot Insulation: Slide the silicone connector boots completely over the joined connection interface to prevent fluid intrusion and shield the shell from grounding against metal conduits.
• Terminal Clearance: Route cables with adequate slack near the machine casing to allow for thermal expansion and mechanical displacement without straining the connection points.
