The Bently Nevada 330930-060-00-00, also cataloged as the 330930-060-00-00 standard extension cable, operates as a signal transmission interface for eddy-current proximity probe systems within the 3300 NSv measurement chain. The 330930-060-00-00 provides controlled impedance conduction between probe and monitoring electronics for vibration and displacement signal routing.

Hardware Specifications

Eddy-Current Signal Transmission Integrity

Within the Bently Nevada 3300 NSv measurement architecture, extension cable capacitance and impedance stability directly affect eddy-current probe scaling accuracy. The 69.9 pF/m capacitance characteristic defines the transfer function between probe tip and proximitor input stage, influencing gap voltage linearity and calibration reference stability under rotor dynamic measurement conditions.

Cross-talk suppression is maintained through coaxial shielding geometry and controlled dielectric spacing. Absence of stainless steel armor reduces mechanical rigidity but does not alter electrical transmission parameters when installed within protected conduit routing.

Field Installation Guidelines

• Maintain continuous shielding continuity from probe connector to monitoring input terminal

• Avoid sharp bending radius below cable manufacturer mechanical tolerance to prevent impedance distortion

• Ensure proper ground termination at system designated single-point earth reference

• Route cable separately from high-voltage VFD output and switching power conductors

• Verify connector seating torque to prevent micro-disconnection under vibration exposure

• Do not install with mechanical tension exceeding allowable pull force during routing

Frequently Asked Questions

Q: Does cable length affect proximity probe calibration output?
A: Yes. Total capacitance and length introduce scaling factors in the eddy-current signal loop.

Q: Is the 330930-060-00-00 electrically active?
A: No. It is a passive transmission medium with no internal excitation circuitry.

Q: Can it be mixed with armored versions in the same system?
A: Electrically yes, but mechanical routing protection levels may differ across segments.

Q: Does impedance remain constant over operating temperature range?
A: Nominal impedance is stable; minor dielectric variation may occur under temperature drift.

Delivery Information

Delivery time: 2–7 days after payment confirmation via DHL / FEDEX / UPS. Anti-static sealed packaging with moisture barrier and coil-stabilized winding to prevent deformation during transport.

Frequently Asked Questions

Q: What is the function of the 50 ohm specification?
A: It defines controlled impedance matching for signal integrity between probe and monitor input.

Q: Does capacitance affect vibration amplitude accuracy?
A: Yes. Cable capacitance contributes to attenuation and phase shift in high-frequency components.

Q: Can this cable be used outside 3300 NSv systems?
A: No. It is matched to Bently Nevada 3300 NSv probe/monitor impedance requirements.
