Information

Overview Manuals Common Applications Product Precautions
Bently Nevada 990-05-XX-03-CN 104M6732-01 is a vibration transmitter that supplies overall vibration input to a machinery control system through two-wire, loop-powered 4-20 ma. Its integrated signal conditioning supports a direct connection to machinery control and monitoring channels.
  • Measurement Role: Overall vibration input to a machinery control system.
  • Series Output Architecture: Two-wire, loop-powered 4-20 mA.
  • Series Conditioning: Integrated Proximitor.
  • Complete configuration: 990-05-XX-03-CN 104M6732-01 identifies this vibration transmitter.

During installation, check supply polarity, loop resistance, probe-chain condition and the receiving channel before applying the measurement to protection or control logic. Verify the live output at the machine operating point after zero, span and cable routing have been confirmed.

Important Notice: The supplied 141612 Rev. Y datasheet is a series reference. It does not identify 104M6732-01 or resolve XX and CN for this execution. Standard ordering meanings and series ratings do not independently confirm special-execution calibration, component compatibility or certification.

Bently Nevada 990-05-XX-03-CN 104M6732-01 Technical Reference (PDF)Bently Nevada 990-05-XX-03-CN 104M6732-01 Installation & Commissioning Guide (PDF)

The technical reference covers 990-series loop, diagnostic and environmental reference data with special-execution boundaries. The installation guide covers identity review, mounting, circuit and diagnostic checks, and functional acceptance.

Compressor control integration
Use 990-family reference data when reviewing an OEM centrifugal-compressor vibration loop, then reconcile the 104M6732-01 configuration with the installed sensing chain.
Pump-channel service
Review the current-loop and target-response checks separately during service of a small-pump channel specified for this complete execution.
Motor or fan vibration trends
Support an OEM overall-vibration trend input where the machine documents define this transmitter, its companion transducer and controller scale.
Instrumented troubleshooting
Use the separate diagnostic interface with suitable isolation when investigating a channel; record the connected instrument and its loading.
Apply the following checks to the exact installed execution; numerical values identified as series references are not a substitute for its special configuration record.
1
Match 104M6732-01 against the machine record and actual unit marking; a different 104M identifier does not establish an equivalent execution.
2
Do not infer XX length from the cable routing distance; confirm the electrical system length and the specified probe/extension combination.
3
Review the actual supplied DIN clips or bulkhead hardware against the standard 03 mounting reference and the cabinet design.
4
Confirm the special calibration and receiving-controller scale before treating a current reading as a vibration amplitude.
5
For a TEST-input check, record the input and loop load; repeat the separate installed probe/target test required by the machine procedure.
6
Isolate grounded AC-powered diagnostic instruments through the 122115-01 adapter and keep the BNC diagnostic cable within the series 3 m limit.
7
Apply environmental limits to the transmitter location and protect coaxial connectors; approval-specific conditions can be narrower than the general family ratings.
8
Investigate persistent Not OK behavior, then document recovery and the intended measurement response before the channel is returned to service.

Technical notes

990-05-XX-03-CN 104M6732-01 should be matched by its complete identifier, installed position and mating components. Before this vibration transmitter returns to service, inspect its mechanical fit and connections and confirm normal operation at the actual monitoring point.
