Eddy-Current Signal Transmission and Rotor Dynamics Support
The Bently Nevada 330854-080-24-CN extension cable maintains the electrical characteristics required for 3300 XL 25 mm proximity probe systems. The cable transfers probe signals between the sensing element and the monitoring channel while preserving eddy-current probe scaling performance.
In addition, the cable assembly supports gap voltage validation procedures used in TSI applications. The connected monitoring system evaluates probe gap conditions through voltage measurement, with typical setup validation using -10 VDC target gap voltage references.
The FluidLoc cable construction reduces fluid migration risks along the cable path. Therefore, the assembly supports installation conditions where contamination resistance and signal stability are required for rotor dynamics monitoring.

Field Installation Guidelines
Install the extension cable according to the approved 3300 XL proximity system wiring arrangement. Maintain separation from high-voltage power cables and strong electromagnetic interference sources to reduce signal disturbance.
Ensure that cable connectors remain clean and properly secured before commissioning. Avoid excessive bending stress near connector areas because mechanical damage can affect signal transmission quality.
During installation, verify cable routing, shielding continuity, and grounding practices according to the monitoring system installation requirements. Confirm the probe gap voltage after connection to validate correct mechanical positioning and electrical operation.
