      Information

      Overview Manuals Common Applications Product Precautions
      Bently Nevada 330930-065-00-CN is a 6.5 m unarmored NSv extension cable. It joins a 0.5 m NSv probe to a matched 7 m Proximitor measurement chain, with the CN approval selection retained.
      • Completes the extension portion of a matched NSv sensing chain.
      • Retains an unarmored execution for supported cable routing.
      • Connects the probe to the separate Proximitor conditioning stage.
      • Keeps the CN marking distinct from electrical-length selection.

      The cable carries the proximity-probe signal to the NSv Proximitor. In a complete 7 m channel, this 6.5 m extension is paired with a 0.5 m NSv probe. The coaxial sensing chain and the Proximitor-to-monitor shielded field circuit are different paths with different installation checks.

      Important Notice: Verify the complete 7 m NSv chain and actual CN marking before fitting. Do not substitute an XL 8 mm extension or assume armor or a protector from the 330930 base family alone; choose connection protection for the installed environment.

      330930-065-00-CN Technical Reference (PDF)330930-065-00-CN Installation & Commissioning Guide (PDF)

      The technical reference covers configuration, signal characteristics and performance conditions. The installation guide organizes system pairing, connection checks and channel commissioning.

      Seven-metre NSv sensing paths
      Join a short NSv probe to the selected conditioner when the documented probe-plus-extension length is 7 m.
      Restricted-clearance machinery
      Route the extension from a compact NSv measurement point on a small compressor, pump or fluid-film-bearing machine.
      Remote conditioning locations
      Place the Proximitor separately from the probe while keeping electrical length and the cable route under the channel design.
      Vibration and position maintenance
      Replace the exact extension execution during service of a matched radial-vibration, thrust-position or phase-reference channel.
      Bently Nevada 330930-065-00-CN installation checks: inspect the 6.5 m unarmored route, pair it with a 0.5 m NSv probe and verify the matched 7 m channel before release.
      1
      Read the complete 330930-065-00-CN identifier: 6.5 m extension, unarmored execution and the retained CN option.
      2
      Pair this extension with a 0.5 m NSv probe and a 7 m NSv Proximitor; keep monitor field wiring outside this sum.
      3
      Support the cable route and maintain the 25.4 mm minimum bend radius; avoid crushing or persistent pull on connectors.
      4
      Join clean mating connectors finger tight; the 0.56 N m maximum is a limit, not a tightening target.
      5
      Select suitable connector protection and insulate exposed probe-to-extension connections from ground under the installed circuit practice.
      6
      Keep the extension within -52 to +177 deg C and assess the separate conditioner temperature at its actual mounting location.
      7
      After restoring the chain, verify target calibration, static gap and the intended monitor response through the machine commissioning procedure.
      8
      Check the actual CN marking, certificate and companion-component circuit conditions before assigning an approval to the completed channel.

      Technical notes

      065 selects 6.5 m and BB00 selects cable without stainless steel armor. Probe-plus-extension electrical length must match the 7 m NSv Proximitor; the sensor-to-monitor field wire is a separate circuit.

      FAQ View All FAQ

      • Which probe length completes the channel with 330930-065-00-CN?
        A 0.5 m NSv probe plus this 6.5 m extension forms the 7 m electrical system. The Proximitor selection must also be 7 m.
      • What does the middle 00 option mean in 330930-065-00-CN?
        BB00 selects cable without stainless steel armor. A connector protector is separately selected under other BB options; it must not be assumed from the base number.
      • Does the monitor field cable count toward 7 m when using 330930-065-00-CN?
        No. The 7 m total is the probe plus extension. The Proximitor-to-monitor shielded field circuit is separate and has its own conductor and frequency-response requirements.
      • Which resistance values apply to checks on 330930-065-00-CN?
        The NSv extension rates are 0.220 ohm/m for the center conductor and 0.066 ohm/m for the shield. Measure the isolated conductor paths separately; do not use probe resistance as the extension reading.
      • How tightly should the connectors on 330930-065-00-CN be joined?
        The recommended connector-to-connector practice is finger tight, with 0.56 N m as the maximum. Inspect seating and clean contacts before reconnecting the chain.
      • Can the conditioner share the upper cable temperature limit of 330930-065-00-CN?
        The extension operates and stores from -52 to +177 deg C. The Proximitor operates to +100 deg C and stores to +105 deg C, so check their separate locations.
      • How does the complete NSv channel using 330930-065-00-CN differ from an XL 8 mm channel?
        The matched NSv system has a 1.5 mm linear range and a recommended 1.0 mm gap. It must use its documented NSv component chain rather than an XL 8 mm cable substitution.
      • Does the CN suffix on 330930-065-00-CN certify every companion component?
        It identifies the selected country-specific execution. Verify each installed component marking and the applicable circuit certificate before assigning an approval to the whole measurement channel.
