Overview Manuals Common Applications Product Precautions
Bently Nevada 990-04-50-01-00 is a DIN-rail 990 Vibration Transmitter configured for a 5 m 3300 NSv system and a 0–100 um peak-to-peak range. It sends proportional shaft-vibration data to a control system over a two-wire 4–20 mA loop.
  • Converts proximity-probe vibration into a two-wire 4–20 mA loop
  • Scales peak-to-peak shaft vibration for direct control-system acquisition
  • Provides a diagnostic Prox Out connection and a test input
  • Suppresses the loop below 3.6 mA when the transducer circuit is Not OK

990-04-50-01-00 installs with 3300 NSv proximity probe, 3300 NSv extension cable, 24 Vdc-class loop supply, control-system analog input in an engineered 990 Vibration Transmitter System configuration.

The commissioning workflow covers installed-hardware matching, controlled start-up and functional verification for this 990 vibration transmitter.

Important Notice: Confirm the complete 990-04-50-01-00 marking, installed-system configuration, field connections and controlled functional test before commissioning or replacement.

Read the applicable Bently Nevada installation instructions before work. Verify 990-04-50-01-00 and the installed 990 Vibration Transmitter System configuration.
1Confirm 990-04-50-01-00 and the 0–100 um full-scale range before loop work.
2Isolate the loop supply and process input before removing the DIN-rail transmitter.
3Verify the installed probe and extension cable form the specified 5.0 m NSv system.
4Gap the probe within the documented operating region before zero/span adjustment.
5Keep loop resistance within the limit established by the actual supply voltage.
6Use the signal-isolation adapter when grounded AC-powered equipment is connected to Prox Out.
7Confirm the Not-OK state drives the loop below 3.6 mA and clears after recovery.
8Prove vibration scaling and control-system response before returning the loop to service.

Technical notes

Technical notes

Set zero and span only after the 5 m NSv probe system is correctly gapped, then verify the two-wire loop across the actual load. Use isolated portable equipment at Prox Out when the test instrument is grounded.

FAQS

  • What vibration range does 990-04-50-01-00 transmit?
    Full-scale option 04 represents 0 to 100 micrometres peak-to-peak.
  • Which proximity system length is required by 990-04-50-01-00?
    System-length option 50 requires a 5.0 m 3300 NSv probe and extension-cable combination.
  • How is 990-04-50-01-00 mounted?
    Mounting option 01 supplies 35 mm DIN-rail clips.
  • What loop supply can be used with 990-04-50-01-00?
    The transmitter requires +12 to +35 Vdc at its terminals and drives a two-wire 4–20 mA loop.
  • What indicates a Not-OK condition from 990-04-50-01-00?
    The output drops below 3.6 mA after a detected Not-OK condition and recovers after the fault clears.
  • How should the probe for 990-04-50-01-00 be gapped?
    Set the NSv probe between 0.5 and 1.75 mm from the target so the selected full-scale range remains available.
  • Can grounded test equipment connect directly to the Prox Out of 990-04-50-01-00?
    Use the manufacturer-specified isolation adapter when grounded AC-powered test equipment is connected to Prox Out.
  • What tests are required after replacing 990-04-50-01-00?
    Check loop supply, burden, probe gap, zero/span, Not-OK action, Prox Out response and control-system scaling.
