The Bently Nevada 330190-045-00-00, also cataloged as the 330190 Extension Cable, operates as a dedicated hardware component for proximity signal transmission within the Bently Nevada 3300 XL Transducer System.
Passive cable component, no external power consumption
Eddy-Current Signal Transmission and Rotor Monitoring Characteristics
The 330190-045-00-00 extension cable maintains the electrical connection between Bently Nevada proximity probes and monitoring instrumentation. Therefore, it supports eddy-current probe scaling by preserving signal characteristics required for shaft displacement and vibration measurement.
The cable construction uses a 75 Ohm triaxial design with FEP insulation. Additionally, the controlled capacitance value supports stable high-frequency signal transmission across the 3300 XL proximity measurement chain.
For rotor dynamics applications, the extension cable provides a controlled impedance path between the probe and signal conditioner. The installation arrangement helps maintain accurate gap voltage validation, including typical Bently Nevada proximity system requirements around -10 VDC target gap conditions.
The triaxial shielding structure reduces electrical interference and supports cross-talk suppression between adjacent monitoring channels. As a result, the cable maintains signal integrity in machinery monitoring installations where multiple proximity channels operate together.

Field Installation Guidelines
Install the 330190-045-00-00 cable according to the Bently Nevada 3300 XL system wiring requirements.
Route the cable away from high-current power conductors, variable frequency drive outputs, and strong electromagnetic interference sources.
Maintain proper separation between multiple proximity signal cables to reduce possible signal coupling.
Connect shielding according to the monitoring system grounding practice and avoid creating unwanted ground loops.
Verify cable connectors, probe connections, and monitor terminals before system commissioning.
Confirm the proximity system gap voltage after installation to validate correct probe positioning and signal chain operation.
Avoid excessive bending, mechanical stress, or damage to the FEP insulated cable surface.
