Bently Nevada 3300/55-01-04-12-12-00-00-05-01 applies two seismic or velocity-transducer channels with selectable measurement processing to absolute casing vibration monitoring, using the exact Channel A 0–20 mm/s pk; Channel B 0–20 mm/s pk scale and the selected interface options.
- Uses the selected Channel A 0–20 mm/s pk; Channel B 0–20 mm/s pk measurement range.
- Accepts Velomitor, 100 mV/in/s; peak velocity.
- Uses epoxy-sealed alarm relay hardware.
- Uses 2X range multiplication.
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 3300/55-01-04-12-12-00-00-05-01 order code, input source and rear connection assembly before installation; then verify each channel through a controlled response test.

Bently Nevada 3300/55-01-04-12-12-00-00-05-01 Technical Reference (PDF)Bently Nevada 3300/55-01-04-12-12-00-00-05-01 Installation & Commissioning Guide (PDF)
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.
Absolute Casing Vibration Monitoring
Apply the selected Channel A 0–20 mm/s pk; Channel B 0–20 mm/s pk 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 3300/55-01-04-12-12-00-00-05-01 configuration before isolation, replacement or return to service.
1
Confirm the full 3300/55-01-04-12-12-00-00-05-01 marking before removing the installed monitor.
2
Record both channel readings and the selected Channel A 0–20 mm/s pk; Channel B 0–20 mm/s pk scale before isolation.
3
Preserve the Velomitor, 100 mV/in/s; peak velocity transducer and sensitivity selection.
4
Retain the epoxy-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
Confirm the 2X multiplier during setpoint and recorder checks.
8
Test each channel, alarm state and downstream response before returning protection to service.
Technical notes
Use a controlled input condition to verify the Channel A 0–20 mm/s pk; Channel B 0–20 mm/s pk scale, Velomitor, 100 mV/in/s; peak velocity 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
-
What does the selected Channel A 0–20 mm/s pk; Channel B 0–20 mm/s pk span control in 3300/55-01-04-12-12-00-00-05-01?The selected measurement span is Channel A 0–20 mm/s pk; Channel B 0–20 mm/s pk. Alarm and recorder scaling must be checked against that span rather than copied from a different range option.
-
What input-chain details must be retained for 3300/55-01-04-12-12-00-00-05-01?This configuration uses Velomitor, 100 mV/in/s; peak velocity. Preserve the transducer family, sensitivity and signal polarity as one measurement chain.
-
Which test separates 3300/55-01-04-12-12-00-00-05-01 measurement scaling from relay operation?The selected alarm output uses epoxy-sealed relay hardware. Contact logic, energization and downstream wiring still require a functional test.
-
How should field wiring be traced for the standard input interface of 3300/55-01-04-12-12-00-00-05-01?No safety-barrier option is selected. Do not move field conductors from a barrier-equipped circuit without an engineering review.
-
Should 3300/55-01-04-12-12-00-00-05-01 be treated as an agency-approved order-code variant?No agency-approval option is selected in this order code. Do not infer an approval from another unit in the same monitor family.
-
What must be checked before comparing 3300/55-01-04-12-12-00-00-05-01 with an unmultiplied monitor?The 2X multiplier expands the usable displayed range from the base scale. Confirm the multiplier state before comparing setpoints or recorder values.
-
What sequence verifies the indication and output path of 3300/55-01-04-12-12-00-00-05-01?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.
-
What information prevents a wrong-variant replacement of 3300/55-01-04-12-12-00-00-05-01?Record the complete model, Channel A 0–20 mm/s pk; Channel B 0–20 mm/s pk scale, Velomitor, 100 mV/in/s; peak velocity input, relay and barrier choices, channel assignments, setpoints, delays and the observed acceptance results.
