330930-065-03-00 Bently Nevada 3300 NSv Extension Cable

Product Description

The Bently Nevada 330930-065-03-00, also cataloged as the 330930 3300 NSv Extension Cable, operates as a dedicated hardware component for extending eddy current transducer signal paths within 3300 NSv machinery protection systems.

Hardware Specifications

Eddy-Current Probe Scaling and Gap Voltage Validation

The 330930-065-03-00 supports an average scale factor of 7.87 V/mm (200 mV/mil), which represents the standard output for eddy current transducers. Furthermore, this extension cable interfaces directly with proximity probes that require precise gap voltage validation. Technicians routinely target -10 VDC gap voltage during initial probe installation to ensure linear measurement range. In addition, the EP insulation provides stable dielectric performance across the full operating temperature range, thereby minimizing signal drift. Consequently, the assembly maintains measurement integrity for radial vibration, radial position, axial thrust position, tachometer, zero speed, and Keyphasor phase reference measurements on fluid-film bearing machines.

Frequently Asked Questions

Q: Can the 330930-065-03-00 be hot-swapped while the 3300 NSv monitoring system remains energized?

A: No. The system must be de-energized before connecting or disconnecting the extension cable. Hot-swapping can induce transient voltages that damage the probe tip or signal conditioning electronics.

Q: What is the minimum bend radius for this coaxial extension cable during installation?

A: Maintain a minimum bend radius of 25.4 mm (1 inch) to prevent deformation of the coaxial dielectric and subsequent impedance changes that degrade signal accuracy.

Q: Is the 330930-065-03-00 interchangeable with the previous 3300RAM extension cable?

A: Yes. The 330930-065-03-00 is mechanically and electrically compatible and interchangeable with the Bently Nevada 3300RAM proximity probe and extension cable assembly.

Field Installation Guidelines

Installers must route the extension cable separately from power conductors and rotating machinery wiring to prevent electromagnetic interference. Moreover, the cable shield should be grounded at the monitoring system end only, following Bently Nevada grounding practices. Additionally, the patented CableLoc design provides 220 N (50 lbf) of pull strength; however, installers should still secure the cable with clamps every 300 mm (12 inches) to avoid strain on the ClickLoc connectors. Finally, the TipLoc molding method creates a robust bond between the probe tip and body, so avoid applying solvents such as ketones or aromatic hydrocarbons near the probe tip, as the FEP jacket resists many chemicals but not all. After installation, verify the gap voltage at -10 VDC targets before final commissioning.
