Information

Overview Manuals Common Applications Product Precautions
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.

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.
