Bently Nevada 330854-040-25-05 3300 XL 25 mm Extension Cable

Description

Designed to maintain signal integrity in demanding machinery monitoring environments, the Bently Nevada 330854-040-25-05 connects 3300 XL 25 mm proximity sensors to their corresponding monitoring systems. This 3300 XL 25 mm Extension Cable is engineered to transmit high-frequency eddy current signals with minimal loss, ensuring accurate vibration, position, and speed measurements on critical industrial rotating machinery.

This specific configuration features a 4.0-meter cable length, armored FluidLoc protection for high-temperature fluid-exposed environments, and carries multiple agency approvals for deployment in hazardous industrial locations. The integrated design protects the coaxial core from external mechanical stresses and prevents fluid migration along the cable length.

Features

• FluidLoc Cable Technology: Option 25 provides armored, high-temperature FluidLoc construction, preventing hazardous or corrosive fluids from migrating through the internal cable structure.
• Optimum Shielding: Armored outer casing provides exceptional mechanical protection against crushing, abrasion, and electromagnetic interference (EMI).
• Coaxial Connection Stability: Equipped with secure coaxial connectors designed to maintain constant contact pressure under continuous industrial vibration.
• Hazardous Area Compliance: Option 05 offers multiple agency approvals, certifying the unit for safe installation in classified areas.

Applications

• Steam and gas turbine shaft vibration and axial displacement monitoring.
• Hydroelectric generator air gap and thrust position measurement.
• Large-scale industrial compressor shaft tracking.
• Heavy duty gearbox and pump diagnostic systems in oil, gas, and chemical processing facilities.

Technical Specifications

Connections and Interfaces

Alternative Models & Compatibility

This cable must be paired strictly with 3300 XL 25 mm proximity sensors and Proximitor sensors. It is not electrically compatible with standard 5 mm, 8 mm, or 11 mm 3300 XL series components. Substituting this cable in smaller-scale sensor loops will result in impedance mismatches and catastrophic measurement errors.

Application Pitfalls & Engineering Notes

The FluidLoc configuration (Option 25) prevents process fluids from migrating through the internal conduit in the event of outer sheath compromise. However, avoid bending the armored housing beyond its minimum physical bend limit during installation. Sharp bends can pinch the internal coaxial core, altering the cable's electrical length and calibration coefficients.

Commissioning & Wiring Tips

When connecting Click-Loc coaxial connectors, ensure they are fully seated until they lock securely. Do not use pliers or heavy tools to tighten the connectors; hand tightening is sufficient. In areas with high environmental moisture, always use connection protection kits to prevent moisture intrusion at the connection interfaces.
