      Information

      Overview Downloads Applications / Compatibility Product Precautions
      • Bently Nevada 3300/48-01-01-00-00 serves existing 3300 rack installations. A single-inch casing-growth channel requires the display range and DC LVDT sensitivity to remain matched throughout the signal path.
      Full-scale range: 0–1 in.
      Transducer match: 1 in. DC LVDT; 9 mV/mil
      Relay configuration: No relays
      Alarm basis: Differential casing movement
      The 0–1 in. scale and 1 in. dc lvdt; 9 mv/mil input setting define the measurement conversion for this order code. Two DC LVDTs track casing motion at the machine supports relative to the fixed foundation. Direct mode allows the individual channels to be inspected, while Differential mode evaluates unequal movement between the two locations.

      Alert and Danger levels are adjustable over 0–100% of full-scale in Differential mode. Display and setting resolution is within ±1.6% of full-scale; alarm repeatability after adjustment is within ±0.4% of full-scale. No relays is the ordered relay configuration. Delay, reset and energized-state settings remain separate commissioning choices that must match the rack alarm arrangement.

      Recorder outputs can be configured for 4–20 mA, 1–5 Vdc or 0 to -10 Vdc, with two direct channels or one differential measurement. A current output supports 0–600 ohms; a voltage output requires at least 10 kilohms. Buffered transducer connections support signal inspection, while the LCD and OK indicators provide adjustment and diagnostic information.
      Controller platform reference: Bently Nevada 3300 casing-expansion system.
      Technical downloads for Bently Nevada 3300/48-01-01-00-00: a manufacturer technical excerpt and an Apter Power installation and commissioning guide.
      The technical reference preserves selected manufacturer pages. The installation guide is compiled by Apter Power for preparation and review; apply the original operating procedures and site controls during work.
      Measurement context: 3300/48-01-01-00-00 connects two matching DC LVDTs to a 3300 rack for casing movement monitoring. The complete order code selects 0–1 in. and no relays.

      Integration boundary: Coordinate the machine mounting arrangement, recorder scaling and rack alarm logic. A matching family name alone does not establish an interchangeable range, input sensitivity or relay module.
      Keep the complete 3300/48-01-01-00-00 configuration aligned with the machine measurement and existing 3300 rack.
      Match both LVDTs

      Use 1 in. dc lvdt; 9 mv/mil inputs with the 0–1 in. scale.

      Select the alarm mode

      Alert and Danger comparisons are available only in Differential mode.

      Review relay hardware

      The order specifies no relays; verify the actual rear module and downstream contact circuit.

      Prove recorder loading

      Use 0–600 ohms for 4–20 mA or at least 10 kilohms for a voltage output.

      Preserve field settings

      Record delay, reset, energized state, recorder mode and upscale direction before replacement.

      Check diagnostics

      Resolve active error indications and verify both channels before returning the measurement to service.

      Technical notes

      Measurement relationship: The LVDTs measure casing displacement relative to the foundation. This is not a rotor differential-expansion probe measurement.

      Alarm configuration: No relays is the ordered relay option. Alert and Danger comparisons operate only in Differential mode; verify relay wiring, reset behavior and delay before service.

      FAQ View All FAQ

      • Which LVDT range matches 3300/48-01-01-00-00?
        The 01 full-scale option selects 0–1 in., and input option 01 selects a 1 in. DC LVDT with a 9 mV/mil scale factor. Match both channels to this configuration; a 2 in. LVDT requires a different input setting.
      • What does 3300/48-01-01-00-00 measure relative to the machine foundation?
        Two DC LVDTs measure casing movement relative to the foundation. Direct mode displays each channel separately; differential mode displays the difference between their measurements.
      • Can 3300/48-01-01-00-00 generate Alert and Danger alarms in Direct mode?
        No. Alert and Danger setpoints apply only to the differential measurement. Direct readings are available for the individual casing-expansion channels.
      • How does the no-relay option affect 3300/48-01-01-00-00 integration?
        The third 00 option specifies no local alarm relays. The rack alarm architecture must provide the appropriate relay arrangement; the no-relay monitor does not supply local relay contacts by itself.
      • Which recorder signals can be selected on 3300/48-01-01-00-00?
        The recorder circuit can be configured for 4–20 mA, 1–5 Vdc or 0 to -10 Vdc. Its measurement mode can be two direct channels or one differential channel, proportional to the selected full-scale range.
      • What load can the 4–20 mA output of 3300/48-01-01-00-00 drive?
        The specified current-output load range is 0–600 ohms, with 0 to +12 Vdc compliance across the load. Voltage-output configurations instead require at least 10 kilohms.
      • How should a flashing green OK indicator on 3300/48-01-01-00-00 be interpreted?
        A 1 Hz flash indicates a transducer that was previously not OK but has recovered. A 5 Hz flash indicates stored error codes. Diagnose the corresponding status before clearing the indication.
      • Where can 3300/48-01-01-00-00 be installed in a 3300 rack?
        It occupies one monitor position. Positions 1 and 2 are reserved for the power supply and system monitor, respectively; confirm the signal-input and relay arrangement at the selected monitor position.
