330854-040-24-05 is a Bently Nevada extension cable for the 3300 XL 25 mm proximity transducer family. Option 040 defines 4.0 m length, option 24 defines high-temperature FluidLoc cable without armor, and option 05 selects the multiple-approval execution.

The cable supports long-range proximity measurements such as turbine differential expansion when it is combined with the exact compatible probe and Proximitor Sensor. Its approvals apply to the documented loop and installation, not to the cable as an isolated generic item.

• Preserves the calibrated electrical path of a 25 mm proximity channel.
• Uses a high-temperature FluidLoc design for demanding turbine-area routing.
• Retains the non-armored option where flexibility and the installed protection method require it.
• Supports approved systems when the associated probe, Proximitor, barriers and wiring follow the applicable documentation.

• Steam-turbine differential expansion measurement.
• Large axial displacement channels using the 3300 XL 25 mm family.
• Replacement of a damaged 4 m cable in an existing high-temperature approved loop.

• Confirm option 24 rather than the visually similar armored option 25.
• Review hot-surface clearance, conduit or tray protection and minimum bend radius before routing.
• Retain certificate and barrier records with the full loop bill of materials.
• Validate zero, direction, usable travel and monitor scaling over the required mechanical movement after service.
