      • 3300 XL 25 mm signal conditioning
      • DIN-rail mounting option
      • Differential-expansion measurement
      • Controlled CN suffix identity

      Apply 330850-51-CN only to a documented 3300 XL 25 mm transducer chain and compatible differential-expansion channel.

      Important Notice: Confirm 330850-51-CN, DIN mounting, CN marking, probe chain, target and monitor scaling before release.

      The first document presents model-specific technical and system data. The second provides a separate installation, connection, commissioning and acceptance workflow.

      Differential expansion
      Measures rotor-to-casing axial movement through the matched 25 mm system.
      Large-range position
      Provides conditioned shaft-position output for compatible monitoring channels.
      Turbine protection
      Supports documented differential-expansion alarm and trip logic.
      Channel restoration
      Restores a controlled 330850 DIN-mounted signal-conditioning position.
      Read the applicable Bently Nevada instructions before work. Verify Bently Nevada 330850-51-CN and the installed system configuration before commissioning.
      1
      Verify the complete 330850-51-CN marking.
      2
      Retain and verify the CN suffix.
      3
      Use only a compatible 25 mm probe and extension cable.
      4
      Confirm DIN-rail mounting and electrical isolation.
      5
      Preserve the documented target geometry and material.
      6
      Provide the correct negative DC supply.
      7
      Set the static gap with the current manufacturer procedure.
      8
      Verify polarity, scale factor, travel and alarm action before release.

      Technical notes

      Technical notes

      Publication 163236 defines the 330850 family and DIN mounting option but does not decode CN. Match the sensor only with the approved 25 mm probe and extension cable, then verify supply, target, gap and channel scaling.
