Product context

Product Description

3300/55 provides two channels of continuous online machinery vibration monitoring from supported Velomitor, High Temperature Velomitor System or Velocity Seismoprobe inputs. The module conditions casing-velocity signals for display, alarm and recorder use in the 3300 rack.

3300/55 requires the transducer mounting point and frequency band to be chosen as part of the measurement design. Filter corner frequencies are jumper-programmed, and a poor sensor mount can reduce amplitude or create a signal that does not represent actual machine vibration.

02
Fast recognition

Three Selection-Relevant Features

Two velocity channels

Independent inputs support one or two documented velocity transducers.

Direct transducer acceptance

Supported Velomitor, HTVS and Velocity Seismoprobe signals do not require a separate interface module.

Field-programmable filtering

High- and low-pass corner options can be changed with the manufacturer-defined jumper arrangement.

ENGINEERING CHECKPOINT

A convenient mounting point may not transmit useful rotor vibration

Casing protection is effective only when machine vibration reaches the sensor location with adequate amplitude and frequency response. Validate the mount and signal before relying on the alarm channels.

Technical Notes

Installation & Measurement Quality

Use a rigid, documented sensor mount on a location that faithfully transmits machine vibration; confirm orientation and cable restraint before setting alarms.

Diagnostics & Filtering

Compare the buffered sensor signal with the configured filter band to distinguish a field-signal problem from a monitor or alarm-setting problem.

Questions from real maintenance and purchasing tasks

Frequently Asked Questions

Q1

Can the existing velocity sensors be reused with 3300/55 after a module change?

Only if the complete monitor input option supports the installed Velomitor, HTVS or Seismoprobe type. Match the transducer sensitivity, power and wiring before using the old alarm settings.

Q2

Why can the vibration level drop after 3300/55 is installed even though the machine condition has not changed?

Inspect sensor mounting rigidity, orientation, cable restraint and the programmed high-/low-pass corners. A loose mount or wrong filter can attenuate the signal before it reaches the alarm logic.

Q3

What should an engineer verify before changing filter jumpers on 3300/55?

Record the existing jumper map, transducer type, machine running-speed range and required measurement band. Change only the documented option and then compare the buffered signal before and after the adjustment.

Q4

How should a technician investigate one Not OK channel on 3300/55?

Compare the two front buffered outputs, check sensor bias/power, wiring continuity and rear-module seating, and swap only a known-good field signal if the procedure allows. This separates a sensor loop fault from a monitor channel fault.

Q5

Can 3300/55 be moved into any spare position in a 3300 rack?

Use an available monitor position only after confirming the rear input/relay module, slot data map and firmware compatibility. Preserve the original channel wiring and alarm configuration during the move.

Q6

What information should a buyer send for an exact 3300/55 quotation?

Provide the full catalog code, transducer family, measurement range, filter corners, recorder and relay options, approvals and clear front/rear labels. The base number alone does not define those selections.

Official-source basis: Bently Nevada 3300/55 Dual Velocity Monitor Specifications and Ordering Information, document 141516-01 Rev. H, and operation manual 130747-01. Configuration-dependent facts require the complete suffix or installed nameplate before final compatibility is accepted.
