Description

Configured for RF signal transmission in Bently Nevada 3500 and 3300 Proximity Transducer Systems, the Bently Nevada 330130-040-00-CN (330130 Standard Extension Cable) provides direct physical/electrical execution.

Suffix Breakdown & Model Matrix

Hardware Specifications

Machinery Monitoring and TSI Characteristics

The Bently Nevada 330130-040-00-CN maintains precise electrical impedance matching to ensure accurate eddy-current probe scaling across the entire system loop. During installation and routine verification, calibrated physical routing is necessary to prevent impedance shifts that skew the required gap voltage validation (-10 VDC targets) critical for accurate rotor dynamics assessment. Integrated shielding within the cable core provides robust cross-talk suppression and external electromagnetic interference mitigation, preventing false vibration spikes in the machinery protection system monitor.

Frequently Asked Questions

Q: What is the specific operational difference between the standard -00 suffix and the -CN suffix version?

A: The electrical performance, physical length, and temperature limits remain identical. The -CN suffix denotes regional industrial compliance and specific hazardous area certifications required for deployment within China.

Q: Can this 4.0-meter extension cable be paired with a 1-meter proximity probe without a Proximitor sensor?

A: No. The extension cable acts as a passive transmission link. It must connect a 1-meter proximity probe directly to a compatible 3300 XL Proximitor Sensor to complete the required 5-meter tuned resonant circuit.

Field Installation Guidelines

• Minimum Bend Radius: Ensure the cable routing adheres to a minimum physical bend radius of 25.4 mm (1.0 inch) for unarmored variants to prevent internal dielectric damage.
• Connector Torque and Insulation: Tighten the miniature coaxial connectors using appropriate finger torque. Apply the required silicone self-locking tape or connector protectors around the junctions to prevent fluid ingress and ground loops.
• Isolation from High-Voltage Lines: Route the extension cable in dedicated, grounded metal conduits separated from high-voltage AC or variable frequency drive (VFD) motor cables to ensure signal integrity.
