The monitor measures two independent radial vibration channels while simultaneously displaying average shaft gap.
4. Product Introduction
The Bently Nevada 3300/16-02-01-00-00-00-00 is a dual-channel vibration monitor designed for continuous machinery protection in the 3300 Monitoring System. It accepts two proximity probe inputs and continuously measures radial shaft vibration together with average shaft position (Gap).
Many facilities continue operating this monitor in turbines, compressors, pumps, and large motors because it integrates directly into existing 3300 racks without modifying field wiring. The 0–19 VDC recorder output allows straightforward integration with legacy DCS and plant data recording systems. Before installation, verify transducer compatibility and rack power supply configuration.
5. Installation & Configuration Guide
Stage 1 – Pre-Installation Preparation (10 Minutes)
⚠️ Safety First
- Notify operations of the planned outage.
- Perform Lock-Out/Tag-Out.
- Remove rack power.
- Wait at least five minutes for power supply discharge.
Tools Required
- Grounded ESD wrist strap
- PH1 screwdriver
- Fluke 115 multimeter
- Wire markers
- Smartphone for documentation
Data Backup
- Record monitor configuration.
- Photograph front panel settings.
- Photograph rear wiring.
- Record channel assignments.
- Verify probe type before removal.
Stage 2 – Removing the Existing Module (5 Minutes)
- Remove the monitor from the rack using the extractor handles.
- Disconnect external recorder wiring if installed.
- Inspect rack connectors.
- Clean dust from the backplane if necessary.
⚠️ Do not discard the old module until commissioning has been completed successfully.
Stage 3 – Installing the Replacement (10 Minutes)
- Wear an ESD wrist strap.
- Confirm the replacement is 3300/16-02-01-00-00-00-00.
- Verify option codes match the original module.
- Slide the monitor fully into the rack.
- Tighten retaining screws evenly.
- Reconnect recorder outputs and field wiring.
Configuration Checklist
- ☑ Correct model number
- ☑ Correct full-scale option
- ☑ Correct transducer type
- ☑ Recorder output verified
- ☑ Rack seating confirmed
Stage 4 – Power-Up & Functional Testing (10–15 Minutes)
Pre-Power Checks
- Measure rack supply voltage.
- Check for wiring shorts.
- Verify connector engagement.
Power-Up Procedure
- Energize the rack.
- Observe OK indicators.
- Verify probe gap voltage.
- Inject a vibration simulator if available.
- Confirm the 0–19 VDC output tracks vibration level.
- Verify DCS receives the analog signal.
- Check alarm functions if applicable.
⚠️ Troubleshooting
- No output signal usually indicates an incorrect transducer selection or rack configuration.
- Incorrect vibration readings frequently result from using a probe sensitivity that does not match the configured monitor option.
- If the recorder output saturates near 19 VDC, verify the measurement range matches the machine operating conditions.

Common Replacement Pitfalls
❗ Firmware and System Configuration
Although the 3300 Series is primarily analog, mismatched rack configuration or monitor options can produce unexpected readings. Always document the original option code before ordering.
❗ Wrong Probe Type
This is one of the most common field mistakes. Option 01 is intended for 7200 or compatible 200 mV/mil Proximitor systems. Installing a different probe sensitivity produces inaccurate vibration measurements.
❗ Recorder Output Wiring
Many older plants use the 0–19 VDC recorder output directly into DCS analog input cards. Verify the receiving input accepts voltage rather than current before energizing.
❗ Rack Connector Damage
I’ve seen technicians force a monitor into a rack with bent guide rails. The monitor survived, but the backplane connector required replacement. If insertion isn’t smooth, stop and inspect the guides.
❗ ESD Damage
These monitors contain sensitive analog circuitry. Always use an ESD strap and avoid handling connector pins directly.
Keep these checks in mind and you’ll eliminate most commissioning problems before startup.
6. Frequently Asked Questions (FAQ)
Q1. Can this monitor be replaced while the rack is energized?
No. The 3300 System was not designed for hot swapping. Remove rack power before replacing the module to prevent connector damage and incorrect machine trips.
Q2. What does the 0–19 VDC output do?
It provides a proportional analog voltage representing the measured vibration or shaft position. Many legacy DCS and recorder systems use this voltage signal for trending and historical data logging.
Q3. Is this model obsolete?
Yes. The 3300 Monitoring System has been discontinued. New Original (New Surplus) inventory is still available from independent suppliers, but stock is limited.
Q4. Will replacing this monitor erase machine settings?
Normally no. The module configuration depends on its hardware option code and rack setup. However, always document alarm setpoints and system configuration before maintenance.
Q5. What equipment is compatible with this monitor?
This configuration is designed for Bently Nevada 3300 Monitoring System racks and accepts compatible 7200 200 mV/mil Proximitor® systems as defined by its option code.
Q6. Why is New Surplus inventory priced below OEM replacement costs?
Most New Surplus units originate from canceled projects, plant modernization programs, or distributor excess inventory. They have not been placed into service but are no longer in current production. Reputable suppliers should provide serial number verification, functional testing, and a documented QC report before shipment.
Q7. What quality inspections should be completed before shipment?
A professional inspection process should include:
- OEM serial number verification
- Anti-counterfeit inspection
- Visual inspection for corrosion, scratches, or repair marks
- Power-up testing in a genuine Bently Nevada 3300 rack
- Functional verification of both vibration channels
- Verification of the 0–19 VDC recorder output
- Electrical insulation testing where applicable
- QC documentation and inspector sign-off
- ESD-safe packaging with heavy-duty export protection
Test reports, startup photographs, and power-up videos should be available upon request.
