General

  • Manufacturer GE / Bently Nevada
  • Model 330354-040-24-05
  • Condition New Original ready stock
  • Product Family 330854-040-25-CN,330354-040-25-05,330354-080-24-05
Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
  • Continuity Check: Use a multimeter to measure the center conductor and shield. An open circuit usually indicates that the cable has been overstretched or that the connector is internally broken.
  • Insulation Resistance: Check the impedance between the shield and the armor. A reading below 10 MΩ may indicate damage to the cable sheath and internal moisture.
  • Connector Inspection: Inspect the ClickLoc gold-plated connectors for corrosion, grease, or metal shavings. Dirt can cause signal attenuation or produce spurious noise.
  • Physical Inspection: Focus on inspecting the armor for severe indentations, kinks, or excessive bending. These physical damages can change the cable impedance (75 Ω), causing system linearity deviations.
  • Clean Connectors: Before connecting, always clean the connectors with anhydrous alcohol swabs to ensure they are free of dust and grease.
  • Tighten to Spec: Tighten only with your fingers; a "click" sound should be heard when locked. Never use pliers or adjustable wrenches to force tighten, as this may damage the seal.
  • Connector Protectors: In humid or oily environments, transparent connector protectors must be installed at the connection points to prevent oil seepage.
  • Bend Radius Required: Maintain a minimum bending radius of 25.4 mm (1.0 in). Never bend at right angles, as this may damage the internal insulation.
  • Armor Grounding: The armor of the extension cable is typically grounded at a single point at the Proximitor sensor end to avoid ground loops.
  • Differential Expansion in Steam Turbines: The most critical application scenario, used to measure the relative thermal expansion between the rotor and casing of large steam turbines.
  • Long Stroke Position Monitoring: With a linear range of 12.7 mm, the 25mm system is commonly used for monitoring the position of turbine guide vanes or the stroke of industrial valves.
  • High Oil Contamination Environments (FluidLoc Performance): This model, suffixed -24, features FluidLoc sealing technology, specifically designed for scenarios where cables may come into contact with oil and to prevent oil seepage along the cable's interior.
  • Harsh Environments: The stainless steel (SST) armor and PFA sheath make it suitable for locations such as chemical plants and power plants with weak acid or alkali corrosion or continuous vibration.
Description
The Bently Nevada 330354-040-24-05 is an essential accessory of the 3300 XL 25mm Proximity Transducer System, engineered to maintain signal integrity in high-temperature, industrial environments.
