Information

Overview Manuals Common Applications Product Precautions
Each channel receives a proximity-transducer signal and a compatible seismic signal, then performs vector combination for continuous machinery protection.
  • Combines relative shaft motion with bearing-housing motion.
  • Provides two independent absolute-vibration channels.
  • Accepts separate proximity and seismic inputs for each channel.
  • Requires correct signal polarity and scale factors for vector calculation.

Use 3300/65 only in the specified monitoring chain and verify the complete signal path after controlled replacement.

Important Notice: Capture the installed 3300/65 interfaces and configuration before removal, then prove the monitored value, status and alarm path after installation.

Before installing Bently Nevada 3300/65, confirm the specified system, interfaces and controlled configuration.
1
Confirm the complete 3300/65 marking and the specified dual probe monitor position.
2
Place the affected machine protection channel in the approved maintenance state.
3
Capture the installed system family, monitor channels and relative input before removal.
4
De-energize the associated monitor, sensor supply or field circuit as the procedure requires.
5
Label every connector, conductor and shield before separation.
6
Inspect mating contacts, mounting hardware and cable condition before installation.
7
Restore the retained configuration and verify signal polarity and proportional response.
8
Function-test the complete alarm, indication and shutdown path before returning the machine to service.

Technical notes

Capture the installed 3300/65 interfaces and configuration before removal, then prove the monitored value, status and alarm path after installation.
