Description

Bently Nevada 330930-040-01-001

  • Technical Specifications:
    • Cable Length: 4.0 meters (13.1 feet)
    • Cable Type: Low-noise coaxial with stainless steel armor
    • Connector Type: ClickLoc miniature coaxial connectors
    • Capacitance: 69.9 pF/m (21.3 pF/ft) typical
    • DC Resistance (Center Conductor): 0.220 Ω/m (0.067 Ω/ft)
    • DC Resistance (Shield): 0.066 Ω/m (0.020 Ω/ft)
    • Operating Temperature: -51°C to +177°C (-60°F to +351°F)
    • Compatibility: 3300 XL NSv proximity probes and 330980 NSv Proximitor sensors
  • Functional Features:
    • Stainless steel armor provides crush resistance and protection against mechanical damage
    • ClickLoc locking connectors prevent accidental disconnection
    • Low-noise coaxial construction shields eddy current signals from EMI
    • Fully interchangeable within the 3300 XL NSv system without individual calibration
    • Suitable for harsh environments with oil, coolant, or chemical exposure
  • Application Scenarios:
    • Industrial compressors in oil and gas processing facilities
    • Chemical plant rotating equipment where cable exposure to corrosive substances is a concern
    • Power generation auxiliary machinery (feedwater pumps, condensate pumps)
    • Steel mill and metallurgical plant rotating equipment
  • Performance Parameters:
    • System sensitivity (when paired with NSv probe and Proximitor): 7.87 mV/μm (200 mV/mil) ± 6.5%
    • Linear range (system dependent): 0.5 to 1.75 mm (20 to 55 mil)
    • Frequency response: 0 to 10 kHz
    • Signal attenuation at 1 kHz: less than 1%
    • Signal attenuation at 10 kHz: less than 5%
  • Material Composition:
    • Low-noise coaxial cable with stainless steel braided armor
    • ClickLoc miniature coaxial connectors with gold-plated contacts
    • Industrial-grade outer jacket over armor layer
  • Structural Features:
    • Stainless steel armored construction for mechanical protection
    • Factory-terminated connectors on both ends
    • Retains compact diameter despite armor layer for routing in confined spaces
  • Working Principle:
    • Identical to the non-armored variant — the extension cable carries the high-frequency eddy current excitation signal from the Proximitor to the NSv probe and returns the gap-proportional modulated signal. The armor layer provides mechanical protection without affecting the electrical characteristics of the inner coaxial structure.
  • Installation Requirements:
    • Route armored cable through conduit or cable tray where additional protection is needed
    • Maintain minimum bending radius of 45 mm
    • Ground the armor shield at one end only to prevent ground loops
    • Ensure connector connections are fully seated and locked
    • Total system length must match the Proximitor configuration
  • Usage Notes:
    • The armored variant is heavier than the non-armored version — account for this in cable support calculations
    • Do not use the armor as a substitute for proper grounding — follow Bently Nevada grounding practices
    • Verify that the armor option is required for the installation environment; non-armored cables are sufficient for clean, protected installations
