      Overview Manuals Common Applications Product Precautions
      Bently Nevada 991-01-XX-01-01 MOD:284318-01 is a loop-powered 991 thrust transmitter that converts a compatible NSv proximity input to a proportional 4 to 20 mA axial-displacement signal. Its 01, XX and MOD blocks remain nameplate-controlled.
      • Two-wire loop-powered thrust transmitter
      • Proportional 4 to 20 mA output
      • Dynamic and gap outputs
      • DIN mounting with CSA Division 2 option

      Use 991-01-XX-01-01 MOD:284318-01 only with the documented NSv probe chain and plant control input under the approved loop-power and scaling arrangement.

      Important Notice: Confirm 991-01-XX-01-01 MOD:284318-01, its custom identity, NSv input, loop power, outputs, mounting and approval before release.

      The first document presents model-specific technical and system data. The second provides a separate installation, connection, commissioning and acceptance workflow.

      Axial position trending
      Provides a proportional thrust-position signal to a control or monitoring system.
      Compact thrust loops
      Uses an integrated NSv Proximitor interface in a field transmitter.
      Diagnostic access
      Provides dynamic and gap outputs for controlled verification.
      Legacy loop replacement
      Preserves the documented custom identity and approval marking.
      Read the applicable Bently Nevada instructions before work. Verify Bently Nevada 991-01-XX-01-01 MOD:284318-01 and the installed system configuration before commissioning.
      1
      Verify the complete 991-01-XX-01-01 MOD:284318-01 marking.
      2
      Retain the leading 01 and XX blocks without interpretation.
      3
      Retain MOD 284318-01 without interpretation.
      4
      Use only a compatible NSv probe system.
      5
      Confirm loop polarity before energizing.
      6
      Set zero and span only with the approved procedure.
      7
      Verify the CSA Division 2 marking against site requirements.
      8
      Prove the 4 to 20 mA, dynamic, gap and inhibit behavior before release.

      Technical notes

      Technical notes

      Publication 141618 defines the 991 family, DIN mounting, CSA Division 2 option and output behavior but does not decode the supplied leading 01, XX or MOD 284318-01. Preserve the full identity and verify the installed NSv chain before substitution.

      FAQS

      • What is Bently Nevada 991-01-XX-01-01 MOD:284318-01?
        It is a two-wire, loop-powered 991 thrust transmitter with an integrated NSv Proximitor interface.
      • How should the 01 range block be handled for Bently Nevada 991-01-XX-01-01 MOD:284318-01?
        Retain the supplied 01 block; the current public standard table lists different range codes and does not decode 01.
      • How should XX be handled for Bently Nevada 991-01-XX-01-01 MOD:284318-01?
        Retain XX exactly and resolve the system configuration from the physical nameplate and controlled order record.
      • Which mounting option applies to Bently Nevada 991-01-XX-01-01 MOD:284318-01?
        The later 01 block specifies DIN-rail mounting clips in the standard ordering table.
      • Which approval applies to Bently Nevada 991-01-XX-01-01 MOD:284318-01?
        The final 01 block identifies the CSA Division 2 approval option in the standard table.
      • What output does Bently Nevada 991-01-XX-01-01 MOD:284318-01 provide?
        It provides a proportional 4 to 20 mA axial-displacement signal plus dynamic and gap outputs.
      • How should MOD 284318-01 be handled on Bently Nevada 991-01-XX-01-01 MOD:284318-01?
        Publication 141618 does not decode this MOD, so retain it as a controlled nameplate identity.
      • What confirms commissioning of Bently Nevada 991-01-XX-01-01 MOD:284318-01?
        Verify the complete marking, NSv input, loop power, zero and span, dynamic and gap outputs, power-up inhibit and final channel response.
