Information

Overview Manuals Common Applications Product Precautions
Bently Nevada 990-05-XX-03-CN 104M1359-01 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 104M1359-01 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 104M1359-01 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 104M1359-01 Technical Reference (PDF)Bently Nevada 990-05-XX-03-CN 104M1359-01 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.

OEM compressor channels
The 990 family supports overall shaft-vibration inputs to centrifugal-air-compressor control systems; confirm this execution against the machine channel.
Small pump monitoring
Use the transmitter family where the pump design specifies a proximity-based overall-vibration loop and documented companion components.
Motor and fan trending
Provide a current-loop trend input in a suitable OEM design after checking the full special identifier and receiving-controller scale.
Service diagnostic access
Inspect the separate dynamic output with suitable isolated equipment; the current-loop trend does not capture the diagnostic waveform.
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
Retain the complete 104M1359-01 identifier; do not replace it with another 990 special number when selecting or recording a unit.
2
Resolve XX from the equipment configuration and component markings before selecting the probe, extension cable or replacement transmitter.
3
Compare the actual mounting hardware with the standard 03 reference for DIN clips and bulkhead screws; secure the arrangement specified for the installed unit.
4
Check terminal voltage, receiving load and actual approval conditions before energizing; the general series power range does not establish a hazardous-area circuit.
5
Use the 122115-01 isolation adapter with grounded AC-powered diagnostic equipment; the series PROX OUT connection is not isolated from the current loop.
6
Keep the series diagnostic BNC cable within its documented 3 m limit and distinguish instrument loading from the controller-loop load.
7
Investigate a persistent below-3.6 mA indication after the series startup interval; do not interpret a Not OK signal as zero measured vibration.
8
Complete both loop-path and installed probe/target checks using the confirmed special configuration before returning the channel to service.

Technical notes

990-05-XX-03-CN 104M1359-01 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.
