Product Describe:
Bently Nevada 330780-X1-CN is a 3300 XL 11 mm Proximitor sensor for a matched probe and extension-cable system with country-specific approval selection.
The 11 mm sensor provides the wider linear range used where a standard 8 mm proximity system does not provide enough displacement reach.
Conditions the matched 11 mm probe and extension-cable signal.
Provides a 100 mV/mil scale factor.
Extends linear displacement measurement to 160 mil.
Supports vibration and static position measurements on rotating machinery.
Use 330780-X1-CN only in the specified monitoring chain and verify the complete signal path after controlled replacement.
Important Notice: Capture the installed 330780-X1-CN 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.
Differential expansion
Measures larger rotor-to-casing movement.
Axial position
Tracks shaft position with extended range.
Radial vibration
Measures non-contact shaft motion.
Machine protection
Feeds proportional signals to compatible monitor channels.
Before installing Bently Nevada 330780-X1-CN, confirm the specified system, interfaces and controlled configuration.
1
Confirm the complete 330780-X1-CN marking and the specified 3300 xl 11 mm proximitor sensor position.
2
Place the affected machine protection channel in the approved maintenance state.
3
Capture the installed transducer family, component role and scale factor 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 330780-X1-CN interfaces and configuration before removal, then prove the monitored value, status and alarm path after installation.
