Product Describe:
Bently Nevada 3300/65 is a two-channel Dual Probe Monitor that combines relative shaft and seismic housing signals for absolute shaft-vibration measurement.
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.
The first PDF covers the product function, system role and technical selection. The installation guide covers identification, connection checks, commissioning and the acceptance test results.
Absolute shaft vibration
Derives rotor motion relative to an inertial reference.
Flexible rotor trains
Separates shaft and casing movement contributions.
Bearing evaluation
Combines probe and seismic measurements at one location.
Legacy monitor replacement
Restores two configured dual-probe channels.
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.
