Information

Overview Manuals Common Applications Product Precautions
Bently Nevada 3300/40-03-01-02-00-00 applies proximity measurement of peak-to-peak and direct rotor position to thermal or gravity bow assessment during slow roll, using the exact 0–20 mils pp / ±20 mils scale and the selected interface options.
  • Uses the selected 0–20 mils pp / ±20 mils measurement range.
  • Accepts 3300/7200 Proximitor, 200 mV/mil.
  • Uses hermetically sealed alarm relay hardware.
  • Uses the base range without a multiplication option.

The complete channel must preserve the transducer source, displayed range, relay interface and barrier selection together. A monitor from the same family can produce a plausible indication while applying a different scale or output arrangement.

Important Notice: Match the complete 3300/40-03-01-02-00-00 order code, input source and rear connection assembly before installation; then verify each channel through a controlled response test.

The technical reference, installation guide and complete product information PDF are separate documents with different scopes. All three apply only to the exact model shown.

Thermal Or Gravity Bow Assessment During Slow Roll
Apply the selected 0–20 mils pp / ±20 mils span to the intended machine measurement.
Two-channel condition monitoring
Keep channel identity from the field transducer through indication and alarms.
Controlled maintenance testing
Inject or apply a known change and compare each response stage.
Protection-system integration
Verify the selected relay and barrier interface with the receiving circuit.
Apply these checks to the exact Bently Nevada 3300/40-03-01-02-00-00 configuration before isolation, replacement or return to service.
1
Confirm the full 3300/40-03-01-02-00-00 marking before removing the installed monitor.
2
Record both channel readings and the selected 0–20 mils pp / ±20 mils scale before isolation.
3
Preserve the 3300/7200 Proximitor, 200 mV/mil transducer and sensitivity selection.
4
Retain the hermetically sealed relay arrangement and its contact logic.
5
Do not introduce a safety barrier without reviewing the complete input loop.
6
Do not infer an agency approval from another order-code variant.
7
Verify the base range is used without multiplication.
8
Test each channel, alarm state and downstream response before returning protection to service.

Technical notes

Use a controlled input condition to verify the 0–20 mils pp / ±20 mils scale, 3300/7200 Proximitor, 200 mV/mil conversion, channel identity and selected output behavior. Restore the recorded alarm, delay, reset, multiplier and bypass states only after the complete path responds correctly.

FAQ View All FAQ

  • Why must 3300/40-03-01-02-00-00 retain its 0–20 mils pp / ±20 mils measurement range?
    The selected measurement span is 0–20 mils pp / ±20 mils. Alarm and recorder scaling must be checked against that span rather than copied from a different range option.
  • Why can the wrong transducer make 3300/40-03-01-02-00-00 display a plausible value?
    This configuration uses 3300/7200 Proximitor, 200 mV/mil. Preserve the transducer family, sensitivity and signal polarity as one measurement chain.
  • How is the selected hermetically sealed relay hardware preserved when replacing 3300/40-03-01-02-00-00?
    The selected alarm output uses hermetically sealed relay hardware. Contact logic, energization and downstream wiring still require a functional test.
  • What does the unbarriered input selection require on 3300/40-03-01-02-00-00?
    No safety-barrier option is selected. Do not move field conductors from a barrier-equipped circuit without an engineering review.
  • What approval assumption must be avoided with 3300/40-03-01-02-00-00?
    No agency-approval option is selected in this order code. Do not infer an approval from another unit in the same monitor family.
  • What confirms that 3300/40-03-01-02-00-00 is operating on its unmultiplied scale?
    No range multiplier is selected, so the stated scale is the active base range. A multiplied setting from another monitor must not be transferred.
  • How should technicians prove channel identity on 3300/40-03-01-02-00-00?
    Apply a controlled input change to one identified channel at a time, then compare the local indication, buffered or recorder signal, alarm state and return to normal.
  • Which acceptance results should be retained for 3300/40-03-01-02-00-00?
    Record the complete model, 0–20 mils pp / ±20 mils scale, 3300/7200 Proximitor, 200 mV/mil input, relay and barrier choices, channel assignments, setpoints, delays and the observed acceptance results.
